C380N

Scrs Overview

The Powerex C380N is a single-phase control silicon-controlled rectifier (SCR) designed for high-power industrial applications. It features a TO-200AB disk button package with ceramic metal-sealed cofired construction. The device supports an average on-state current of 250 A and withstands repetitive peak voltages up to 1.2 kV. Key electrical characteristics include a maximum non-repetitive surge current of 3,500 A, a circuit commutated turn-off time of 200 µs, and a critical rate of rise of off-state voltage of 200 V/µs. It operates within a temperature range of -40 °C to 125 °C.

Scrs Feature Summary

• Robust thermal management via disk button package design
• High surge current capability for demanding load conditions
• Fast circuit commutated turn-off timing

Scrs Applications

• Industrial phase control systems
• High-power motor drives
• Resistive heating controllers

Scrs Procurement Notes

Verify the specific suffix or variant against official Powerex documentation to ensure correct voltage and current ratings. Confirm package compatibility and mounting requirements before integration. Request manufacturer datasheets for detailed thermal resistance and derating curves. Validate component authenticity through authorized distribution channels.

Scrs Selection Notes

Select based on required blocking voltage levels and continuous current demands. Ensure the gate trigger parameters align with available drive circuitry capabilities. Consider thermal dissipation constraints and heatsinking solutions for the operating environment. Verify that the turn-off time meets the frequency requirements of the application circuit.

Scrs Part Context

This component belongs to the Powerex C380 series of high-power thyristors. The series includes variants with different voltage ratings such as the C380AX500 and C380CX500. These devices share similar physical packaging and general performance profiles tailored for heavy-duty power electronics.

Scrs Replacement Considerations

Direct substitutes may include other 250A, 1200V SCRs in TO-200AB packages from manufacturers like Littelfuse or Semikron. Verify pinout compatibility and thermal interface dimensions. Cross-reference gate trigger specifications to ensure driver circuit compatibility without modification.
