FS300R12A6P1B Overview

The Infineon FS300R12A6P1B is a 1200 V, 300 A three-phase IGBT power module from Infineon's EasyPACK family using the latest IGBT6 / TRENCHSTOP 6 generation technology. It integrates six IGBT switches in a standard three-phase inverter topology with anti-parallel Emitter Controlled 3 diodes and a built-in NTC thermistor for temperature monitoring, all housed in a chassis-mount package rated for 1200 V collector-emitter voltage and 300 A nominal current per switch.

An IGBT module (Insulated Gate Bipolar Transistor module) is a high-power semiconductor switch that combines the easy gate-drive of a MOSFET with the low conduction loss of a bipolar transistor, packaged as an integrated three-phase or half-bridge block for industrial inverter applications. IGBTs sit hierarchically under power semiconductors -> discrete semiconductors -> wide-bandgap-adjacent silicon switches, enabling motor drives, solar inverters, and UPS systems at multi-kilowatt power levels.

Key features include low VCE(sat) for reduced conduction loss, integrated NTC for direct junction-temperature feedback to the DSP/MCU, TVj op = 150 degrees C high-temperature operation, and a press-fit / screw-mount mechanical interface for industrial chassis assembly. The module's 1200 V blocking voltage supports DC-link buses up to 800 V nominal (per typical 600 V / 690 V AC mains with 1.4x derating headroom), and 300 A continuous current delivers three-phase output in the 100-200 kW range for general-purpose drives.

The IGBT6 (TRENCHSTOP 6) cell architecture uses micro-pattern trench field-stop technology with thin-wafer processing, achieving a tighter VCE(sat)/Eoff tradeoff than the previous IGBT4 generation. The integrated emitter-controlled 3 diode delivers low reverse-recovery loss, while the on-chip NTC thermistor enables precise thermal derating in variable-frequency drive firmware.

Typical applications include industrial variable-frequency drives for three-phase motors, three-phase solar string inverters, uninterruptible power supplies, and industrial servo drives where the module handles 100-250 kW output stages. The 1200 V class also supports battery chargers and high-power welding equipment. The integrated NTC simplifies inverter thermal management firmware compared to discrete IGBT designs.

When designing with the FS300R12A6P1B, mount the module to a heatsink or cold plate with proper thermal interface material, keep the DC-link capacitor loop area minimal to suppress switching transients, and use isolated gate drivers with reinforced isolation per IEC 61800-5-1. Maintain VCE breakdown derating - the 1200 V rating requires careful snubber design at DC-link voltages above 800 V.

The FS300R12A6P1B delivers 300 A continuous current at 1200 V, matching three-phase 690 V AC mains after rectification with adequate safety headroom (DC bus ~ 1080 V DC). Its IGBT6 cells offer low VCE(sat) and Eoff, enabling 8-16 kHz switching for current-ripple management while sustaining 150 C Tvj op. Placed between a 1080 V DC link and a 690 V AC motor in the inverter stage, the module replaces discrete IGBT half-bridges, integrating six switches plus the integrated EC3 diodes. Compared to IGBT4 modules, the A6P1B drops switching loss by approximately 15-25%, raising inverter efficiency by 0.2-0.4 percentage points in the 100-250 kW class.

⚡

Three-Phase Solar String Inverters (PV Inverters)

For high-power three-phase string or central solar inverters, the FS300R12A6P1B handles DC-link voltages of 1000-1100 V (corresponding to 1500 V DC open-circuit PV strings) while delivering 300 A per IGBT leg. Its IGBT6 silicon improves European weighted efficiency by 0.2-0.4 percentage points, which over a 25-year inverter lifetime translates into hundreds of kWh of additional energy harvested. Integrated NTC enables direct junction-temperature feedback to the inverter's MPPT controller for thermal derating during continuous full-power operation. Used in 100-200 kW commercial-scale solar inverters where module efficiency and reliability dominate total cost of ownership.

🖥️

Uninterruptible Power Supplies (UPS) - 100-200 kW Class

Online double-conversion UPS systems for data centers and industrial critical loads require bidirectional inverter/rectifier stages with high efficiency and high fault-current capability. The FS300R12A6P1B's 1200 V blocking voltage supports 800 V DC battery bus designs, while its 300 A rating covers 200 kVA three-phase UPS outputs at 0.8 power factor. IGBT6 low-Eoff reduces thermal load at typical UPS switching frequencies of 6-10 kHz, easing cooling in tightly racked data-center deployments. The integrated EC3 anti-parallel diodes provide the rectifier mode path, eliminating external diode bridges and reducing BOM count.

⚡

Industrial Battery Chargers and DC Fast Chargers

High-power three-phase industrial battery chargers used in EV fast-charging stations, forklift battery banks, and telecom DC plants require robust bidirectional power conversion. The FS300R12A6P1B supports 800 V nominal DC bus operation at full 300 A per phase, delivering 100-250 kW charging stages for 400 V / 800 V EV battery packs. Its 150 C Tvj op rating extends component lifetime in continuous full-power charging profiles common in commercial EV depots. Designers pair the module with bidirectional gate drivers and CAN-FD control for ISO 15118-compliant EV charging communication.

🏭

Welding and Plasma-Cutting Power Converters

Industrial welding inverters and plasma cutters demand high peak current handling, robust short-circuit tolerance, and high thermal cycling endurance. The FS300R12A6P1B's 1200 V breakdown and 300 A nominal current support 400-600 A peak weld currents when pulsed, while the IGBT6 silicon offers improved short-circuit withstand time (SCWT) over IGBT4 generations. Tvj op = 150 C extends inverter lifetime under harsh thermal-cycling conditions typical of welding equipment. The EasyPACK 1B chassis-mount package suits the high-vibration, high-thermal-shock environment of industrial welding machines.

🤖

Industrial Servo Drives and Robotics

High-bandwidth industrial servo drives for robotics and CNC machines require switching frequencies of 8-32 kHz with precise current control. The FS300R12A6P1B's IGBT6 cells reduce Eoff loss at 16 kHz by approximately 20-30% vs IGBT4 predecessors, enabling servo drives with higher torque-bandwidth and finer position-loop control. The integrated NTC thermistor provides real-time junction-temperature feedback for servo dynamic thermal management in compact machine-tool heads. Used in conjunction with resolver-to-digital converters and high-resolution current-sense ADCs for precision motion control in 50-150 kW servo-amplifier designs.

FS300R12A6P1B vs FS300R12OE4B81BPSA1 - which is better for solar inverters?
For solar inverter applications, the FS300R12A6P1B (IGBT6 generation) is generally preferred over the FS300R12OE4B81BPSA1 (IGBT4 generation) because the newer silicon achieves lower switching loss per ampere, improving European efficiency weighted at 96-99% by approximately 0.2-0.4 percentage points. The EasyPACK 1B housing and three-phase topology remain similar. The IGBT6 module also has a higher Tvj op = 150C rating. For new solar designs, prefer FS300R12A6P1B; use FS300R12OE4B81BPSA1 only for service replacements.
When should I choose FS300R12A6P1B over the FS300R12P family?
Choose the FS300R12A6P1B when your inverter design targets higher switching frequencies (8-16 kHz), needs lower Eoff losses, or must operate continuously at 150C junction temperature. Choose the older FS300R12* P-series modules when you need lowest unit price, accept lower efficiency, or design legacy service replacement boards where qualified BOM must remain unchanged. The FS300R12A6P1B's EasyPACK 1B footprint is forward-compatible with prior EasyPACK generations, simplifying PCB-free upgrade paths.
What is the best drop-in replacement for FS300R12A6P1B?
The best drop-in cross-family replacement from Infineon is the FS300R12OE4P, an IGBT4-generation 1200 V / 300 A six-pack in the same EasyPACK 1B footprint. Pin-to-pin compatibility is maintained per the Infineon EasyPACK family datasheets, but expect slightly higher VCE(sat) and Eoff because of the older IGBT4 silicon. For new designs, prefer the A6P1B to avoid the efficiency penalty.
Where to download the FS300R12A6P1B datasheet PDF?
The official Infineon FS300R12A6P1B datasheet can be downloaded from Infineon's product page (search the part number on infineon.com) or via XAIPART's datasheet link. The datasheet contains the maximum ratings table (Vces=1200V, Ic=300A), IGBT6 switching-loss curves, thermal-resistance figures (Rth(j-c) per switch and per module), recommended heatsink torque values, and the isolation voltage rating per UL/IEC standards. The EasyPACK 1B package outline drawing is included in section 8 of the document.
What is the pinout configuration of FS300R12A6P1B?
The FS300R12A6P1B is housed in the Infineon EasyPACK 1B module with standardized DC+, DC-, and per-phase U/V/W power terminals on the top side of the module, plus an 11-pin control-pin header for the six gate/emitter pins and the on-board NTC thermistor (two terminals). Pinout and gate-driver connections are documented in the datasheet's chapter 5. EasyPACK 1B modules share the same control-pin assignment across the EasyPACK family, simplifying upgrades between IGBT4 and IGBT6 modules.
How much does the FS300R12A6P1B dissipate at 200 A load?
Estimated: at 200 A continuous collector current per switch with VGE = 15 V and an IGBT6 VCE(sat) of approximately 1.7 V at the chip level (Tj = 125 C), per-switch conduction loss is approximately 340 W. For a six-pack module in a three-phase inverter, two switches conduct at any time (one high-side + one low-side), so total module conduction loss is roughly 680 W. Adding switching losses at 8 kHz with typical Eon+Eoff of 30 mJ per switch gives approximately 480 W additional, summing to approximately 1160 W total dissipation that the heatsink must remove.
Does the FS300R12A6P1B include a gate driver?
No, the FS300R12A6P1B does not include a gate driver; the EasyPACK 1B package only contains the bare IGBT die with gate and emitter pins brought out to the control header. An external isolated gate driver such as the Infineon 1ED3120MC12H or 2ED020I12FA must be used per switch, with +15 V / -8 V gate drive and reinforced isolation per IEC 61800-5-1. The control header simplifies gate-drive wiring by exposing all six gates to a single connector.
What is the maximum junction temperature of FS300R12A6P1B?
The Infineon FS300R12A6P1B has a maximum operating junction temperature (Tvj op) of 150 C, defined per the IGBT6 generation reliability derating. Continuous operation above Tvj op = 150 C accelerates module thermal aging, while the Tj max (instantaneous short-term limit) is typically 175 C per Infineon's datasheet. Thermal design must ensure Tvj op remains at or below 150 C at the worst-case load profile.
Is the FS300R12A6P1B RoHS compliant?
Yes, the Infineon FS300R12A6P1B is RoHS compliant per Infineon's product-compliance database and bears the lead-free / RoHS-compliant terminal plating designation. REACH compliance is also stated for this part. The compliance markings appear in section 1 of the datasheet and on the module label. The EasyPACK 1B housing meets IEC 61249-2-21 halogen-free PCB material standard for industrial applications.
What mounting torque is required for FS300R12A6P1B?
The Infineon FS300R12A6P1B must be mounted to a flat heatsink with typically 5 Nm to 6 Nm torque per power terminal screw (M5/M6 size, depending on hardware variant) and 1.5-2.5 Nm for the control-header mating connector. Mounting the module requires a thermal interface material (TIM) - either a pre-applied thermal pad or a 1-2 mil thermal grease layer - between the baseplate and the heatsink. Detailed torque values and TIM selection guidance are in section 6 of the datasheet.
What are the key specifications of FS300R12A6P1B that engineers should know?
The Infineon FS300R12A6P1B is a 1200 V / 300 A three-phase IGBT module using IGBT6 (TRENCHSTOP 6) silicon, integrating six IGBT/anti-parallel diode pairs and an NTC thermistor in the EasyPACK 1B chassis-mount package. Key specs: Vces = 1200 V, Ic = 300 A nominal per switch, Tvj op = 150 C, internal NTC available for thermal feedback, and EasyPACK 1B form factor with chassis-mount screw terminals. The IGBT6 cell delivers lower Eoff than IGBT4, enabling higher switching frequency and inverter efficiency per the manufacturer datasheet.

Selection Guide

Choose the FS300R12A6P1B when designing new three-phase inverters in the 100-250 kW range where switching frequency above 8 kHz and high European efficiency are critical - solar inverters, UPS, and high-end VFDs benefit most from IGBT6 silicon's lower Eoff. Choose the FS300R12OE4P as a drop-in service replacement for legacy IGBT4 inverter designs, or when unit-cost dominates efficiency. Choose the FS300R12KE3 (IGBT3) only when servicing very old inverter equipment where the BOM must remain on a single qualified part. The EasyPACK 1B chassis-mount package is shared across all three options, simplifying mechanical integration. All four candidates in this comparison share the same EasyPACK 1B / AG-EconoPACK footprint and 1200 V / 300 A ratings.

Design Notes

Estimated: at 200 A continuous per IGBT with VCE(sat) = 1.7 V (IGBT6 silicon), each switch dissipates ~340 W; for a six-pack with two switches conducting at a time, conduction loss is ~680 W. With typical IGBT6 switching losses at 8 kHz, an additional ~480 W is dissipated, totaling ~1160 W per module. The EasyPACK 1B baseplate Rth(c-s) of ~0.05 K/W requires a heatsink with Rth(s-a) <= 0.08 K/W (forced-air) to keep Tvj op <= 125 C at 40 C ambient. Always derate heatsink performance by 20% if natural convection is used.

Keep the DC-link capacitor loop (DC+ -> IGBT -> DC- -> capacitor) physically small, ideally within 30-50 mm total loop length, to suppress voltage overshoot during IGBT turn-off. Use laminated bus bars instead of separate cables for high-current paths in the 200-300 A class. Place the gate-driver board within 50 mm of the control header to minimize gate-loop inductance; desaturate (DESAT) detection requires typical 6.5 V threshold with 5 us blanking time. Add a 0.1 uF X7R bypass capacitor directly across each gate-emitter pair to suppress Miller-turn-on transients.

Do not exceed Vce breakdown by operating DC-link voltage above 800 V DC nominal (which equals 1130 V peak on a 690 V AC mains). At 1200 V the part is at its absolute rating - always leave 30-50% derating headroom. Always use isolated gate drivers (1ED3120, 2ED020) - never drive the gates from logic-level signals without isolation, as the IGBT emitters switch at the DC- bus which moves relative to logic ground. The integrated NTC requires a 1 mA bias and 10 kohm pull-up for accurate temperature conversion. Do not apply conductive thermal grease to the baseplate; use a 50-100 um silicone-free thermal pad to avoid contamination migration onto the ceramic substrate.
