Procurement Notes

Verify the specific suffix VAO against official Microchip documentation to confirm RoHS compliance and material composition details. Ensure the procurement channel provides valid traceability for automotive or industrial grade requirements. Cross-reference the datasheet revision date to confirm parameter consistency before integration into final designs.

Selection Notes

Select this component when a single-phase rectification application requires high voltage blocking capability combined with fast switching speeds. The 40 A current rating suits moderate to high-power converters. Consider the TO-247-2 footprint for board layout constraints and verify that the 1000 V rating exceeds the circuit's peak inverse voltage demands.

Part Context

This part belongs to Microchip’s Fast Recovery Epitaxial Diode (FRED) portfolio, specifically the APT series. These devices are engineered for efficiency in power conversion.
