ACPL-P340-560E Présentation
A gate drive optocoupler is a type of optoelectronic isolator that combines an LED input with a high-current CMOS/BCDMOS output stage to provide galvanic isolation between low-voltage control circuitry and high-voltage power switches such as IGBTs and power MOSFETs. The gate drive optocoupler sits hierarchically under optocoupler -> isolator -> semiconductor, providing reinforced isolation that protects logic-level microcontrollers and gate-driver controllers from the high dV/dt transients and high DC bus voltages typical of motor drives, solar inverters, and industrial power conversion equipment.
Key features include rail-to-rail output voltage swing (VCC to VEE), 1.0 A minimum peak output current, 200 ns maximum propagation delay, and 50 ns maximum pulse-width distortion. Based on Broadcom BCDMOS process technology, the device delivers approximately twice the speed of previous-generation gate drive optocouplers, while consuming only 3.5 mA typical supply current and supporting a wide 15 V to 30 V supply range that directly drives the gate-emitter capacitance of standard 600 V/1200 V class IGBT modules.
Typical applications include motor control inverter gate drives for industrial servo drives and variable-frequency drives (VFDs), solar photovoltaic (PV) inverter power stages, induction-heating resonant converters, and uninterruptible power supply (UPS) systems. The 50 kV/µs common-mode transient immunity (CMTI) ensures reliable switching in noisy high-side bootstrap configurations where IGBTs switch at 10-20 kHz with 600-1200 V DC bus rails.
When designing with this device, place a 0.1 µF bypass capacitor directly across VCC and VEE pins, use a minimum 1 µF bulk capacitor at the gate of the driven IGBT, and verify creepage/clearance distances satisfy end-equipment IEC 61800-5-1 reinforced insulation at the working voltage. The ACPL-P340-560E is the tape-and-reel, IEC/EN/DIN EN 60747-5-5 approved version of the family; choose ACPL-P340-000E for tube packaging without IEC approval.

Industrial Motor Drive (VFD/AC Servo) IGBT Gate Drive
The ACPL-P340-560E delivers 1.0 A peak gate-drive current to switch IGBT modules rated up to 50 A and 1200 V in three-phase variable-frequency drives (VFDs) and AC servo drives. Its 3750 Vrms reinforced insulation meets IEC 61800-5-1 for inverter safety, while the 50 kV/µs CMTI prevents false triggering from high-side bootstrap noise at 10-20 kHz switching. The rail-to-rail output (VCC to VEE) directly drives +15 V/-5 V or 0/-15 V gate-bias rails on standard 600 V/1200 V IGBT modules from Infineon, Mitsubishi, and Fuji without an external buffer.

Solar PV Inverter IGBT/MOSFET Driver
The ACPL-P340-560E provides reinforced isolation between the low-voltage control FPGA/MCU and the high-voltage DC bus in solar photovoltaic string and central inverters. Its 200 ns maximum propagation delay supports switching frequencies up to 50 kHz in three-level NPC and H6 bridge topologies, while the 50 kV/µs CMTI tolerates the dV/dt at the IGBT switching node. The Stretched SO-6 surface-mount package simplifies automated PCB assembly and reduces parasitic inductance versus through-hole DIP alternatives, improving switching loss in high-density string inverter designs.
Recommandé
Uninterruptible Power Supply (UPS) IGBT Driver
In online double-conversion UPS systems, the ACPL-P340-560E drives the IGBT half-bridge stages in the rectifier and inverter power sections. The 3750 Vrms isolation separates the 384 VDC battery bus and 230/480 VAC grid from the DSP-based digital controller, satisfying IEC 62040-1 reinforced insulation. The 1.0 A peak output current switches 50 A/600 V IGBT modules at 16-25 kHz with low switching loss, while the 3.5 mA typical ICC keeps quiescent losses low in standby bypass mode for energy-efficiency compliance.
Recommandé
Induction Heating Resonant Inverter
The ACPL-P340-560E drives IGBT half-bridge modules in series-resonant induction-heating inverters operating at 20-100 kHz. Its 200 ns maximum propagation delay and 50 ns pulse-width distortion preserve the timing accuracy required for zero-voltage-switching (ZVS) and phase-shift PWM control of the resonant tank. The rail-to-rail output voltage swing ensures full enhancement of the IGBT gate at high switching frequencies where gate-charge losses dominate efficiency. Reinforced 3750 Vrms isolation protects the resonant controller from the high-frequency tank voltage at the induction coil.
Recommandé
Welding Machine Inverter
The ACPL-P340-560E is used in MMA/TIG/MIG welding inverter power stages to drive primary-side IGBT modules in the resonant full-bridge topology. The 1.0 A gate-drive current handles 50 A/1200 V IGBTs operating at 20-50 kHz switching frequency, while the 3750 Vrms reinforced isolation protects the welding control PCB from the high dv/dt at the switching transformer secondary. The wide 15 V to 30 V VCC range accommodates the variable gate-bias requirements of different IGBT generations from multiple vendors.
Recommandé
EV Charging Station (DC Fast Charger) PFC Stage
In 50-350 kW electric-vehicle DC fast chargers, the ACPL-P340-560E drives the IGBT modules in the totem-pole or bridgeless PFC rectifier front end. The 50 kV/µs minimum CMTI tolerates the 100 kV/µs transients of SiC MOSFET co-existence in mixed semiconductor power stacks. The Stretched SO-6 footprint allows PCB layout reuse between the ACPL-P340 family and higher-current ACPL-P341/ACPL-P343 variants when scaling charger power from 50 kW to 350 kW without redoing the gate-driver schematic.

Principaux différenciateurs
- Higher peak gate-drive current at lower cost than ACPL-P341 (vs ACPL-P341-000E)
- Wider creepage / 8 mm clearance than competing gate-drive optos (vs VO3150A)
- Surface-mount Stretched SO-6 vs through-hole DIP alternatives (vs HCPL-3120)
Notes de conception
Place a 0.1 µF low-ESR ceramic bypass capacitor directly across VCC (pin 5) and VEE (pin 3), within 2 mm of the package pads. Add a 1 µF bulk electrolytic or ceramic capacitor in parallel for high-frequency gate-charge delivery. Keep the gate-drive trace from VOUT (pin 4) to the IGBT gate shorter than 25 mm to minimize parasitic inductance, which can cause gate-voltage ringing above the IGBT VGE(max) rating during fast switching.
Maintain minimum 8 mm creepage and clearance between input-side (LED anode/cathode) and output-side (VCC/VEE/VOUT) copper pours to satisfy IEC 60747-160002 reinforced insulation at the working voltage of the end equipment. For 1200 V DC bus applications, increase creepage to 10 mm minimum per IEC 61800-5-1. Do not route any primary-side signals or ground plane beneath the optocoupler to preserve isolation barrier integrity.
Do not connect pin 6 (NC) to any signal, ground, or supply rail - leaving it floating prevents internal coupling that could degrade CMTI performance. The LED forward current IF must be set between 7 mA and 16 mA for reliable operation; below 7 mA the output stage may not switch fully, while above 16 mA the LED lifetime shortens. Use a current-limiting resistor in series with the LED to set IF based on the controller supply voltage.
The Stretched SO-6 package has a typical theta_JA of 150 C/W. At the 3.5 mA typical supply current and 30 V VCC, internal power dissipation is approximately 105 mW, giving a junction temperature rise of 16 C above ambient. At maximum supply (30 V, 5.5 mA) dissipation reaches 165 mW (25 C rise) - well within the 110 C maximum junction rating. No heatsink is required for typical IGBT gate-drive duty cycles.
