C430M

Scrs Overview

The C430M is a Phase Control Silicon Controlled Rectifier (SCR) manufactured by Powerex Inc. It features a standard recovery type with a maximum repetitive peak off-state voltage of 600 V and an average on-state current of 1070 A. The device utilizes a clamp-on Press-Pak (Pow-R-Disc) package, specifically TO-200AB/A-PUK, designed for high-current industrial applications. Key electrical parameters include a maximum non-repetitive surge current of 1480 A at 50 Hz and 1600 A at 60 Hz, a maximum gate trigger voltage of 3 V, and a maximum gate trigger current of 150 mA. The on-state voltage drop is limited to 2.6 V, ensuring efficient power handling within the specified operating temperature range.

Scrs Procurement Notes

Verify that the specific order matches the C430M part number exactly, as Powerex offers variants with different voltage or current ratings within the same family. Confirm the requirement for the clamp-on Press-Pak mounting style, as this dictates the necessary hardware for installation. Ensure the application circuit supports the 600 V blocking voltage and 1070 A continuous current limits. Check for any specific datasheet revisions that may affect gate trigger parameters. Always reference the official manufacturer datasheet for final electrical validation before integration.

Scrs Selection Notes

Select the C430M when designing systems requiring high average current handling in a compact press-pack form factor. This component is suitable for applications where low on-state voltage drop and high surge capability are critical. Consider the 600 V voltage rating to ensure adequate margin against line transients. Evaluate the thermal management requirements associated with the clamp-on interface to maintain junction temperatures within the specified -40°C to 125°C range. Compare against other phase control SCRs if higher voltage blocking is needed.

Scrs Part Context

The C430M belongs to the C350 series of Phase Control SCRs from Powerex Inc., which are designed for demanding industrial power conversion tasks. This series utilizes the Pow-R-Disc technology, combining high electrical performance with reliable mechanical clamping. The C430M specifically addresses the need for high current density in phase control applications, distinguishing itself from lower-rated models like the C350M through its significantly higher average on-state current capacity while maintaining similar package dimensions.

Scrs Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other Powerex phase control SCRs only if electrical parameters such as voltage, current, and package type are identical.
