Single Diodes Procurement Notes

Verify the specific suffix or variant code against official Powerex documentation to ensure compatibility with required voltage and current ratings. Confirm RoHS compliance status if restricted substances are mandated. Check datasheet revisions for any updates to mechanical dimensions or thermal resistance values before finalizing procurement specifications.

Single Diodes Selection Notes

Select this component when a 100A continuous current rating and 1400V blocking voltage are required in a stud-mount configuration. Ensure the cooling system can maintain the junction temperature below 200°C under worst-case operating conditions. Compare thermal impedance characteristics with alternative packages if space constraints exist.

Single Diodes Part Context

The A170M belongs to the A170 series of high-power rectifiers from Powerex. This series is engineered for demanding industrial environments where reliability and high current handling are critical. The DO-205AA package provides a standardized mounting interface for integration into larger power modules or discrete assemblies.

Single Diodes Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure replacement devices match the 100A current, 1400V voltage, and DO-205AA mechanical footprint.
