Scrs datasheet and documents for C154B

C154B

Scrs Overview

The Powerex C154B is a single-element Silicon Controlled Rectifier (SCR) designed for high-power industrial applications. It features a T50 stud mount package with three terminals and supports an RMS on-state current of 109.9 A, equivalent to 110,000 mA. The device withstands repetitive peak reverse voltages and direct gate blocking voltages up to 200 V. Key electrical characteristics include a maximum non-repetitive surge current of 1800 A, a holding current of 500 mA, and a circuit turn-off time of 10 µs. It operates at temperatures up to 125 °C.

Scrs Feature Summary

Fast switching capability with a nominal circuit turn-off time of 10 µs
Robust thermal management via T50 stud mount construction
High surge current tolerance for demanding power environments

Scrs Applications

Industrial motor drives requiring fast commutation
High-current DC power supply circuits
Resistive load control systems

Scrs Procurement Notes

Verify the specific manufacturer origin, as the C154B designation appears in databases associated with both New Jersey Semiconductor and Powerex Inc. Confirm that the selected unit matches the required 200 V rating and T50 package dimensions. Ensure compliance with RoHS3 standards if applicable to the specific production batch.

Scrs Selection Notes

Select this component when a 200 V SCR with approximately 110 A continuous current capacity is required. The 10 µs turn-off time makes it suitable for faster commutation scenarios compared to standard recovery devices. Verify that the mounting hardware accommodates the T50 stud configuration and that the gate drive can supply the necessary 150 mA trigger current.

Scrs Part Context

The C154B belongs to the family of high-power silicon controlled rectifiers manufactured by Powerex Inc. These components are engineered for robust performance in heavy-duty power electronics. The T50 package provides a standardized mechanical interface for efficient heat dissipation and secure installation in high-current modules.

Scrs Replacement Considerations

The C152PA is a related Powerex SCR but operates at a significantly higher voltage rating of 1.1 kV. Substitution requires verifying that the lower 200 V rating of the C154B is sufficient for the application's peak reverse voltage requirements.
