C152A

Scrs Overview

The Powerex Inc. C152A is a standard recovery Silicon Controlled Rectifier (SCR) designed for high-power industrial applications. It features a TO-83 (TO-208AD) leaded package with stud mounting capability. The device supports a repetitive peak off-state voltage of 1100 V and an RMS on-state current of 100 A. Key electrical characteristics include a maximum gate trigger current of 150 mA, a holding current of 500 mA, and a non-repetitive surge current rating of 1400 A to 1500 A at 50/60 Hz. It operates within a junction temperature range of -40°C to 125°C.

Scrs Feature Summary

• Standard recovery type construction optimized for general-purpose rectification and inversion circuits.
• Robust mechanical design utilizing a TO-83 stud mount configuration for efficient thermal dissipation.
• High surge current handling capacity suitable for demanding power electronics environments.

Scrs Applications

• Industrial motor drives and variable frequency drives
• High-voltage DC power supplies
• Inverter circuits in renewable energy systems

Scrs Procurement Notes

Verify the specific suffix or variant against official datasheets, as generic part numbers may obscure critical differences in thermal resistance or pinout configurations. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as regulatory requirements vary by region and production batch. Ensure that the ordering documentation explicitly references the correct Powerex Inc. catalog number to avoid substitution errors with similar SCR families.

Scrs Selection Notes

Select this component based on its 1100 V blocking voltage and 100 A continuous current ratings to ensure adequate margin for the target circuit's peak loads. Evaluate the thermal management requirements carefully, as the TO-83 package relies on proper mounting torque and heatsink interface for effective heat transfer. Verify that the gate drive circuit can supply the required 150 mA trigger current reliably under all operating conditions.

Scrs Part Context

The C152A belongs to the broader C150 series of high-power SCRs manufactured by Powerex Inc., now part of Semikron Danfoss. This series is widely recognized in heavy industry for its reliability in converting AC to DC or controlling AC power. The C152A specifically represents a standard recovery variant within this lineup, distinct from fast-recovery models used in high-frequency switching applications.

Scrs Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Engineers must consult official cross-reference guides from Powerex/Semikron Danfoss or perform detailed parameter matching with equivalent TO-83 SCRs from other manufacturers before implementation.
