ACEFC304-HF

Overview

The ACEFC304-HF is a standard recovery rectifier manufactured by Comchip Technology, designed for surface mount applications. It features a maximum DC reverse voltage of 200 V and an average forward current rating of 3 A. The device utilizes a DO-214AB (SMC) package and operates within a junction temperature range of -55°C to +150°C. Key electrical characteristics include a maximum forward voltage of 900 mV at 3 A and a low reverse leakage current of 10 µA at 200 V. The component holds AEC-Q101 qualification for automotive reliability and exhibits a fast recovery time of 20 ns.

Feature Summary

• Automotive-grade reliability certified under the AEC-Q101 standard
• Fast recovery performance with a 20 ns reverse recovery time
• High thermal stability supporting operation up to 150°C junction temperature

Applications

• Automotive power supply circuits requiring high reliability
• General purpose rectification in industrial electronics
• DC-DC converter output stages

Procurement Notes

Verify the specific ordering suffix and packaging configuration against the manufacturer's latest documentation before procurement. Confirm that the requested quantity aligns with the standard manufacturing pack size to avoid unnecessary handling fees or partial reel charges. Ensure compliance with RoHS3 directives as specified in the environmental classification data provided by Comchip Technology.

Selection Notes

Select this component when a surface mount rectifier with 3 A continuous current capability and 200 V blocking voltage is required. The DO-214AB package offers robust soldering capabilities for automated assembly processes. Consider the 20 ns recovery time suitability for higher frequency switching applications compared to standard general-purpose diodes.
