T707043074BY

Overview

The T707043074BY is a Silicon Controlled Rectifier (SCR) manufactured by Powerex Inc. It features a single element configuration housed in a T70 package with three pins. The device supports a maximum repetitive peak reverse voltage of 400V and a maximum DC gate trigger current of 500 mA. Its rated RMS on-state current is 475A, with a corresponding on-state current rating of 475,000mA. The component utilizes a stud mount form factor.

Feature Summary

High-current handling capability suitable for industrial power applications
Fast switching performance with a circuit commutated turn-off time of 10 µs
Robust metal encapsulation designed for high-power thermal management

Applications

Industrial motor drives
Power supply systems
Inverter circuits

Procurement Notes

Verify the specific datasheet version to confirm electrical tolerances and thermal characteristics before integration. Ensure that the mounting interface matches the T70 post/stud specification. Cross-reference the pinout diagram with the target PCB or busbar design to guarantee correct polarity and connection integrity during assembly.

Selection Notes

Select this component when a 400V blocking voltage and 475A continuous current capacity are required. The T70 package provides a standardized mechanical footprint for high-power modules. Consider the 10 µs turn-off time for applications demanding rapid commutation cycles within the specified voltage and current limits.

Part Context

This SCR belongs to the T70 series from Powerex Inc., designed for high-power thyristor applications. The series typically offers robust construction for demanding environments. The T70 package is widely used in industrial settings requiring reliable high-current switching solutions with standardized mounting interfaces.

Replacement Considerations

Consult official cross-reference lists for compatible substitutes. Verify that any replacement maintains the 400V V(RRM), 475A I(T)RMS, and T70 package dimensions to ensure mechanical and electrical compatibility without redesigning the host system.
