C390M

Scrs Overview

The C390M is a Silicon Controlled Rectifier (SCR) manufactured by Powerex Inc. It features a maximum repetitive peak reverse voltage of 1400V and an RMS on-state current rating of 700A. The device utilizes a POW-R-DISC-3 package, providing a disk button form factor with three terminals. Key electrical characteristics include a maximum non-repetitive surge current of 8000A and a gate trigger voltage maximum of 5V. The component operates within a temperature range of -40°C to 125°C and incorporates a ceramic metal-sealed cofired encapsulation for durability in high-power applications.

Scrs Feature Summary

• High current handling capability with 700A RMS on-state rating
• Robust mechanical design using POW-R-DISC-3 disk button packaging
• Electrically isolated construction suitable for common heatsink mounting

Scrs Applications

• Industrial motor drives and control systems
• High-power DC-to-AC inversion circuits
• Static power switching in heavy machinery

Scrs Procurement Notes

Verify the specific suffix against official Powerex documentation to confirm exact voltage and current ratings, as variations exist within the C390 series. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Ensure ordering specifications match the required thermal and electrical parameters for the target application environment.

Scrs Selection Notes

Select this component based on its 1400V blocking capability and 700A continuous current capacity. Evaluate the thermal impedance requirements associated with the POW-R-DISC-3 package to ensure adequate heatsinking. Compare against similar Powerex models like the C390PD or C391PN if different voltage or current thresholds are necessary for the circuit design.

Scrs Part Context

The C390M belongs to the Powerex C390 series of high-power silicon controlled rectifiers. This series is characterized by robust disk-style packaging designed for industrial-grade reliability. These components are engineered for demanding power electronics environments requiring high surge withstand capabilities and stable performance under varying thermal conditions.

Scrs Replacement Considerations

Direct substitutes may include other Powerex models within the C390 family, such as the C390PD, provided voltage and current ratings align. Verify pinout compatibility and thermal interface dimensions when considering cross-brand alternatives. Consult manufacturer datasheets to ensure equivalent switching speeds and gate trigger characteristics.
