C781PM

SCRs - Modules Overview

The C781PM is a Phase Control Silicon Controlled Rectifier (SCR) manufactured by Powerex. It features an average on-state current rating of 2500 Amperes and supports repetitive peak reverse voltage ratings ranging from 1600 Volts to 2100 Volts. This high-power semiconductor device is designed for robust industrial applications requiring precise phase control capabilities.

SCRs - Modules Feature Summary

• High current handling capability with a 2500 Ampere average rating
• Flexible voltage blocking options across the 1600V to 2100V range
• Engineered specifically for phase control circuit topologies

SCRs - Modules Applications

• Industrial motor drives
• High-power rectification systems
• Static power switching applications

SCRs - Modules Procurement Notes

Verify the specific voltage suffix or variant against the official Powerex datasheet, as the C781PM series encompasses multiple voltage ratings between 1600V and 2100V. Confirm package dimensions and thermal characteristics match the target heatsink design before procurement.

SCRs - Modules Selection Notes

Select this component based on the required average current of 2500A and the specific system voltage needs within the 1600V-2100V window. Ensure gate drive requirements align with SCR triggering specifications and verify thermal management solutions can handle the associated power dissipation.

SCRs - Modules Part Context

The C781PM belongs to the C781 family of Phase Control SCRs produced by Powerex. This series includes variants such as C781L and C781LA, which share the same 2500A current rating but may differ in specific voltage breakdown thresholds or minor packaging details.

SCRs - Modules Replacement Considerations

Direct substitutes include other models within the Powerex C781 series, such as the C781L or C781LA, provided the voltage rating matches the application requirement. Cross-manufacturer replacements require careful verification of current, voltage, and thermal parameters.
