T700123504BY

Overview

The T700123504BY is a standard recovery Silicon Controlled Rectifier (SCR) manufactured by Powerex Inc. It features a TO-209 variant package designed for stud mounting applications. Key electrical specifications include a maximum on-state average current of 250 A and a blocking voltage rating of 400 V. The device requires a maximum gate trigger current of 150 mA and a maximum gate trigger voltage of 3 V to initiate conduction.

Feature Summary

• Standard recovery type construction suitable for general power control applications
• Robust mechanical design utilizing a TO-209 variant stud mount package
• Capable of handling high continuous on-state currents up to 250 A

Applications

• Industrial motor drive systems
• High-power rectification circuits
• Static power switching units

Procurement Notes

Verify the specific suffix BY against official Powerex documentation to confirm exact thermal and mechanical tolerances. Ensure compatibility with existing heatsinking infrastructure due to the stud mount configuration. Cross-reference datasheet parameters for gate sensitivity requirements before integration into driver circuits.

Selection Notes

Select this component when a 400 V blocking capability and 250 A RMS current handling are required in a stud-mount form factor. Evaluate thermal management needs based on the TO-209 package constraints. Confirm that the 150 mA gate trigger requirement aligns with available drive circuitry capabilities.

Part Context

This SCR belongs to Powerex's lineup of high-current thyristors designed for robust industrial environments. The TO-209 variant package provides a standardized interface for secure mechanical attachment and efficient heat dissipation through the base plate, distinguishing it from leaded or surface-mount alternatives.

Replacement Considerations

Consult official substitution guides for equivalent 400 V, 250 A stud-mount SCRs. Verify pinout compatibility and thermal resistance values before replacing existing units in assembly.
