A430P

Single Diodes Overview

The A430P is a general-purpose rectifier diode manufactured by Powerex Inc. It features a single-phase, one-element silicon construction housed in the DO-200AB (B-PUK) clamp-on package. The device is rated for a maximum repetitive peak reverse voltage of 1000V and an average forward rectified current of 1000A. This component is designed for high-current industrial applications requiring robust clamping capabilities.

Single Diodes Feature Summary

Single Diodes Procurement Notes

Verify the specific suffix designation against official Powerex documentation to confirm exact electrical tolerances and thermal characteristics. Ensure the procurement channel provides valid manufacturer traceability. Confirm that the DO-200AB package dimensions match the intended mechanical assembly requirements before finalizing orders.

Single Diodes Selection Notes

Select this component when high current capacity and reliable reverse blocking are required in a compact clamp-on form factor. Consider the thermal management needs associated with 1000A operation. Verify compatibility with existing busbar or clamp mounting structures. Evaluate the 1000V rating against system transient voltages to ensure adequate safety margins.

Single Diodes Part Context

This part belongs to the A430 series of general-purpose rectifiers from Powerex Inc., which offers various voltage ratings within the same current class. The series utilizes standardized DO-200AB packages to facilitate integration into high-power industrial systems. The A430P specifically denotes the 1000V variant within this lineup.

Single Diodes Replacement Considerations

Consult official cross-reference lists for verified substitutes such as other A430 series variants with matching current ratings. Ensure any replacement maintains the DO-200AB footprint and clamp-on interface. Verify equivalent thermal resistance and reverse voltage specifications.
