The GT40QR21 is a silicon N-channel IGBT from Toshiba Semiconductor and Storage, designed for voltage-resonant inverter switching applications. It features a monolithically integrated freewheeling diode (RC-IGBT) within the chip. The device supports a collector-emitter voltage of 1200 V and a continuous collector current of 40 A. Key electrical parameters include a typical saturation voltage of 1.9 V at 40 A and a maximum junction temperature of 175°C. Switching performance includes a fall time of 0.20 µs and a reverse recovery time of 0.60 µs. It is housed in a TO-3P(N) package with a thermal resistance of 0.65 °C/W.
Verify component authenticity by checking markings against official datasheet specifications. Confirm RoHS compatibility status directly with Toshiba sales representatives as indicated in documentation. Ensure handling procedures account for electrostatic discharge sensitivity during installation and storage.
Select this component specifically for voltage-resonant inverter designs where its integrated freewheeling diode functionality is required. Evaluate thermal management requirements based on the specified junction-to-case thermal resistance and power dissipation limits under expected operating conditions.
This discrete IGBT belongs to Toshiba's 6.5th generation product line. It utilizes RC-IGBT technology to optimize switching speed and conduction losses. The device was commercially produced starting in December 2010.
No public confirmed substitute part numbers are available in the provided documentation.
The product is dedicated exclusively to voltage-resonant inverter switching applications.
It consists of an enhancement mode IGBT with a freewheeling diode monolithically integrated into the same chip.
The DC collector current is rated at 40 A, while the pulsed collector current (1 ms) is rated at 80 A.
