AES1H-HF

Overview

The AES1H-HF is a general-purpose super fast recovery rectifier manufactured by Comchip Technology. It features a 500 V repetitive peak reverse voltage and a 1 A average forward current rating. The device utilizes the DO-214AC (SMA) surface-mount package for compact circuit integration. Key electrical characteristics include a maximum forward voltage of 1.3 V at rated current, a low reverse leakage current of 5 µA, and a fast recovery time of 35 ns. It supports a surge current of 30 A and operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

• Super fast recovery technology ensures minimal switching losses in high-frequency applications.
• Automotive-grade reliability with AEC-Q101 qualification for harsh environment stability.
• Low forward voltage drop contributes to improved system efficiency and reduced heat generation.

Applications

• Automotive power supply circuits
• DC-DC converter output rectification
• High-frequency switching power supplies

Procurement Notes

Verify the specific suffix and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Confirm that the component meets all required automotive qualification standards for your specific application environment. Ensure the ordering documentation explicitly references the AES1H-HF part number to avoid substitution errors with similar generic rectifiers.

Selection Notes

Select this component when a 500 V reverse voltage rating and 1 A continuous current capacity are required in an SMA package. It is suitable for designs prioritizing fast switching speeds and automotive durability over ultra-low cost alternatives. Consider thermal management requirements based on the 1.3 V forward voltage drop under load conditions.
