The GT20J341 is a silicon N-channel IGBT from Toshiba Semiconductor and Storage, designed for motor driver applications. It features a TO-220SIS package with an integrated FRD between the emitter and collector. Key electrical parameters include a collector-emitter voltage of 600 V and a DC collector current rating of 20 A at Tc = 25°C. The typical saturation voltage is 1.5 V at IC = 20 A. Thermal characteristics specify a junction-to-case thermal resistance of 2.78 °C/W for the IGBT and 4.23 °C/W for the diode. The device supports a short-circuit withstand time of 5 µs and operates within a junction temperature range up to 150°C.
Verify component authenticity by checking markings against official datasheet specifications. Confirm RoHS compatibility status directly with Toshiba sales representatives as indicated in documentation. Review the Toshiba Semiconductor Reliability Handbook for derating concepts and handling precautions before integration into designs.
Evaluate thermal management requirements based on specified junction-to-case thermal resistance values. Ensure gate drive voltages remain within the ±25 V absolute maximum rating. Consider the 5 µs short-circuit withstand capability when designing protection circuits for high-power switching scenarios.
This discrete IGBT belongs to Toshiba's sixth-generation product line aimed at improving efficiency in power conversion systems. The inclusion of a built-in FRD simplifies circuit design for inductive loads commonly found in motor control applications.
Consult official Toshiba documentation for verified substitute part numbers. Cross-referencing with other models requires careful comparison of pinouts, voltage ratings, and thermal characteristics to ensure functional compatibility.
The device can withstand a short circuit for 5 µs under specified conditions (VCC = 300 V, VGG = +15 V/0 V, Tj ≤ 125°C).
Yes, the GT20J341 includes a Fast Recovery Diode (FRD) connected between the emitter and collector.
The typical collector-emitter saturation voltage (VCE(sat)) is 1.5 V when the collector current is 20 A.
