BSM50GX120DN2 概要
An IGBT (Insulated-Gate Bipolar Transistor) is a voltage-controlled power semiconductor that merges the high input impedance of a MOSFET gate with the low conduction loss of a bipolar transistor. It sits in the silicon hierarchy below MOSFET and above BJT, and together with its freewheeling diode forms a switching pole. The IGBT is the workhorse of medium-power conversion between roughly 600V and 6500V, where MOSFETs become conduction-loss-limited and thyristors cannot be pulse-width modulated, and where it functions as a power-management building block inside motor drives, UPS, solar inverters, and induction-heating converters.
Key features include a 1200V collector-emitter rating (Vces), 50A continuous collector current (Ic), a square RBSOA (Reverse Bias Safe Operating Area) rated for hard-switched operation at full current and voltage, an integrated NTC thermistor for junction-temperature monitoring, and an isolated ceramic baseplate for direct heatsink mounting without additional insulation. The ECONOPACK 2 housing provides a low-inductance, low-thermal-resistance mechanical platform that simplifies busbar layout and reduces stray inductance at the switching node.
The module uses Infineon's trench-field-stop IGBT3 generation technology with soft-switching-optimized freewheeling diodes, balancing low Vce(sat), low turn-off losses (Eoff), and a robust short-circuit withstand of typically 10 microseconds at 600V/2x rated current. The three-phase bridge is partitioned as a six-pack plus NTC, allowing direct paralleling for higher-current stacks only after derating and thermal validation. Gate drive is normally supplied by a bootstrap- or isolated-supply-based driver IC such as the IR2136 or 2ED020I12-F2.
Typical applications include AC inverter drives for industrial motors, solar string and central inverters, three-phase UPS rectifier-inverter stages, and welding-machine power stages. The 50A/1200V rating maps cleanly onto 400V class AC mains-fed inverter outputs up to roughly 22 kW when properly heatsunk.
When designing with this device, observe the SOA: hard-switched IGBTs must stay within Vce(sat) and reverse-bias limits at DC-link voltages up to 1200V with controlled dV/dt and adequate dead-time. Always consult the manufacturer datasheet for RBSOA curves, isolation voltage, and minimum heatsink torque values before substituting alternate modules.

主な用途
BSM50GX120DN2 の用途: 6 件s: Industrial AC Inverter Drives, Solar String Inverters, Uninterruptible Power Supplies (UPS), Induction Heating Power Stages, Welding Machine Power Converters, Servo Drive and Robotics.
Industrial AC Inverter Drives
The BSM50GX120DN2 fits three-phase industrial AC drives in the 15-22 kW range where a pre-assembled 1200V/50A IGBT bridge is required. Its 1200V Vces rating handles DC-link voltages generated from 400V/480V mains via a passive or active rectifier, while the 50A Ic allows continuous phase current delivery to induction and permanent-magnet motors. Compared with discrete IGBTs, it removes the burden of busbar design, isolation thermal stacks, and gate-driver tracing. Place the module on a forced-air-cooled heatsink with the integrated NTC tied to a comparator or microcontroller ADC for derating or trip protection.
おすすめ
Solar String Inverters
In three-phase solar string inverters, the BSM50GX120DN2 acts as the inverter-stage IGBT bridge, converting high-voltage DC bus (up to 1000V) into 400V AC grid output. Its 1200V rating provides margin for overshoot and grid transients, while the 50A continuous current supports string combiner boxes for commercial-scale arrays. The integrated NTC simplifies thermal monitoring in outdoor enclosures, and the isolated ECONOPACK baseplate allows direct cold-plate mounting. Designers pair it with Infineon EconoPIM variants for PFC + inverter combos in compact designs targeting 10-20 kW output.
おすすめ
Uninterruptible Power Supplies (UPS)
Online double-conversion UPS systems in the 15-30 kVA range use the BSM50GX120DN2 in the inverter stage that feeds critical loads after battery boost. The 1200V/50A rating ensures the bridge can transfer battery-bus voltages up to ~800V with full sinusoidal current up to 50A per phase without saturating. The integrated freewheeling diodes support bidirectional current flow during UPS transitions between grid and battery modes, and the NTC informs load-dependent cooling. Carefully designed L-C filters downstream smooth the PWM output to THD-compliant sine wave for sensitive IT/medical loads.
おすすめ
Induction Heating Power Stages
In industrial induction-heating inverters, the BSM50GX120DN2 acts as the resonant switching pole that drives a high-frequency tank circuit (typically 20-100 kHz). The trench-field-stop IGBT3 technology inside the module offers competitive switching losses versus older PT/NPT IGBTs at the typical 20-50 kHz operating frequency of these power stages. The 1200V/50A envelope accommodates the resonant overshoot common in un-loaded tank operation. Pair with a soft-resonant ZCS/ZVS controller and a water-cooled or forced-air heatsink rated for the continuous conduction duty cycle.
おすすめ
Welding Machine Power Converters
Welding-machine power converters in the 10-20 kW class leverage the BSM50GX120DN2 as the primary switching bridge for the inverter stage that feeds the high-frequency transformer and rectifier to the welding output. The 50A continuous current handles transient arc-load spikes when the welding arc strikes, while the 1200V Vces provides margin for primary-side resonance and flyback-induced overshoots. The module's rugged ECONOPACK 2K packaging is designed to withstand mechanical vibration typical of portable welding units, and the integrated NTC enables over-temperature protection during duty-cycle-rated continuous operation.
おすすめ
Servo Drive and Robotics
Industrial servo drives and robotics arms in the 15-22 kW range use the BSM50GX120DN2 as the three-phase bridge that drives permanent-magnet servo motors with high dynamic current demand. The 50A rating supports peak torques needed for acceleration, while the 1200V Vces isolates the high-voltage DC bus (typically 600-800V) cleanly from the gate driver and control circuits. The fast switching frequency (typically 8-16 kHz for servo operation) is supported by the IGBT3 generation inside the module, and the integrated NTC feed enables real-time thermal monitoring during high-acceleration duty cycles.

設計ノート
Estimated: At full 50A Ic and 1200V Vces in the ECONOPACK 2K package, total module dissipation depends heavily on switching frequency and duty cycle. At 8 kHz PWM with hard switching, calculate P_total = (Vce(sat) x Ic x duty) + (Eon + Eoff) x fsw; ensure heatsink theta_sa < (150 - T_ambient) / P_total. Use thermal interface material rated for the full isolation voltage and mount with the manufacturer-specified torque to avoid uneven thermal contact. Always monitor the integrated NTC for derating or shutdown well before the junction rating is exceeded.
Keep DC-link capacitor loop area to the absolute minimum by placing bulk capacitors physically adjacent to the DC+ and DC- power terminals of the module. Stray inductance in this loop creates Ldi/dt overshoot during turn-off that can exceed Vces and destroy the IGBT. Use laminated or sandwich busbars for the DC-link on higher-power designs, and route gate-driver traces with a tight gate-emitter return path to avoid Miller-induced false triggering during high dV/dt events.
Do not operate the module without proper gate drive - the IGBT gates must be held at defined emitter-referenced potentials (typically +15V on, -8V off) for reliable switching. Do not exceed Vge = +/- 20V; over-voltage on the gate-emitter junction can permanently damage the oxide. Verify the short-circuit withstand time (SCSOA) when sizing the protection time constant - the BSM50GX120DN2 family is typically rated for 10 us at the test conditions, so set DESAT protection slightly below that value with margin.
Estimated: For a 22 kW three-phase inverter application (400V AC mains, DC-link ~700V), the per-phase RMS current is roughly 32A, well within the 50A Ic rating of the BSM50GX120DN2. Verify that the switching frequency selected (typically 4-8 kHz for industrial drives, up to 20 kHz for servo) keeps switching losses within the heatsink capability by checking the Eon/Eoff curves in the manufacturer datasheet. Remember that at high DC-link voltages (toward 1200V), switching losses grow non-linearly and may force derating at higher fsw.
