C430PC

Scrs Overview

The Powerex C430PC is a Phase Control Silicon Controlled Rectifier (SCR) designed for high-power industrial applications. It features a disk button package with four terminals and ceramic metal-sealed cofired construction. The device supports an average on-state current of 680 Amperes and offers a repetitive peak reverse voltage range from 500 to 1300 Volts. Key electrical characteristics include a circuit turn-off time of 125 µs, a maximum DC gate trigger current of 125 mA, and a maximum DC gate trigger voltage of 5 V. It withstands a critical rate of rise of off-state voltage of 200 V/µs and has a maximum RMS on-state current of 1070 A.

Scrs Feature Summary

• High thermal stability enabled by ceramic metal-sealed cofired packaging
• Capable of handling significant non-repetitive peak surge currents
• Designed for phase control applications requiring fast circuit commutation

Scrs Applications

• Industrial motor drives
• High-power rectification systems
• Phase-controlled AC power regulation

Scrs Procurement Notes

Verify the specific voltage rating suffix required for the application, as the base model covers a range up to 1300 Volts. Confirm the package type matches the SC-4 disk button specification. Ensure the gate trigger parameters align with the driving circuit capabilities before procurement.

Scrs Selection Notes

Select based on the required blocking voltage level within the 500-1300 V range. Consider the RMS current requirements against the 1070 A limit. Evaluate the thermal management needs given the 680 A average current capability and the 125 °C maximum operating temperature.

Scrs Part Context

This component belongs to the Powerex Phase Control SCR series, which utilizes robust disk button packages for high-current handling. These devices are engineered for reliability in demanding environments, featuring ceramic sealing to protect the silicon junction from moisture and contaminants.

Scrs Replacement Considerations

Direct cross-compatibility depends on matching the exact voltage rating and pin configuration. Verify that substitute components meet or exceed the 125 µs turn-off time and 200 V/µs dv/dt ratings. Consult manufacturer substitution guides for equivalent disk button SCRs.
