BT152-500RT,127

Scrs Overview

The BT152-500RT,127 is a planar passivated Silicon Controlled Rectifier (SCR) manufactured by WeEn Semiconductors. It is housed in a SOT78 (TO-220AB) plastic package designed for through-hole mounting. The device features a rated repetitive off-state voltage of 500 V and an RMS on-state current capability of 20 A. Key electrical parameters include a maximum gate trigger current of 32 mA, a non-repetitive peak on-state current of 200 A, and a maximum junction temperature of 150°C.

Scrs Feature Summary

• Planar passivated silicon construction for high thermal cycling performance
• High surge current capability suitable for demanding applications
• Designed for high junction temperature operation up to 150°C

Scrs Applications

• Industrial control systems requiring high inrush current handling
• Power regulation circuits with high thermal cycling demands
• Applications necessitating robust bidirectional blocking voltage capabilities

Scrs Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct packaging configuration. Confirm that the requested variant matches the required industrial qualification standards. Cross-reference the component marking with the datasheet to validate authenticity. Ensure the procurement channel provides valid traceability records for quality assurance purposes.

Scrs Selection Notes

Select this component when the application requires a TO-220AB packaged SCR with a 500 V rating and 20 A continuous current capacity. Consider its 150°C maximum junction temperature for environments with elevated thermal loads. Evaluate the 200 A surge current rating against potential inrush requirements. Verify compatibility with existing gate drive circuitry given the 32 mA maximum trigger current specification.

Scrs Part Context

This part belongs to the BT152 series of Silicon Controlled Rectifiers from WeEn Semiconductors. The series is characterized by planar passivation technology, offering improved reliability compared to standard structures. The BT152-500RT variant specifically targets applications needing high thermal stability and robust performance in industrial power electronics environments.

Scrs Replacement Considerations

Direct substitutes within the same family include the BT152-500R,127, which shares identical electrical characteristics but may differ in packaging orientation or reel specifications. Verify pinout compatibility and thermal resistance values before substitution.
