AU1FJHM3/H

Overview

The AU1FJHM3/H is a single standard recovery rectifier manufactured by Vishay Semiconductors. It features a maximum repetitive peak reverse voltage of 600 V and an average forward current rating of 1 A. The device utilizes the eSMP trademark and is housed in a DO-219AB-2 surface-mount package. Key electrical characteristics include a forward voltage of 850 mV, a maximum surge current of 35 A, and a reverse current of 5 uA. The component supports a wide operating temperature range from -55 C to +125 C.

Feature Summary

• Engineered for robust performance in demanding power conversion applications
• Features avalanche capability for enhanced reliability under transient conditions
• Utilizes glass passivation for protection against mechanical stress

Applications

• General-purpose rectification in power supplies
• Freewheeling diode applications in inductive loads
• DC-DC converter circuits requiring high voltage blocking

Procurement Notes

Verify the specific suffix and marking codes on the physical component against the official Vishay datasheet to confirm authenticity. Ensure the ordering part number matches the exact electrical specifications required for the design. Check for RoHS compliance status as indicated in the manufacturer's documentation before finalizing procurement orders.

Selection Notes

Select this component when a 600 V rated standard recovery rectifier with 1 A continuous current capacity is required in a compact surface-mount form factor. Consider the 850 mV forward voltage drop for thermal management calculations. Verify that the DO-219AB-2 footprint aligns with the PCB layout constraints and that the 125 C maximum junction temperature meets the application's thermal environment requirements.

Part Context

This device belongs to the SE20FJ series of surface-mount rectifiers designed for general-purpose use. It shares the same DO-219AB-2 package profile as other members in the family but is distinguished by its specific 600 V voltage rating and 1 A current handling capability. The series emphasizes reliability through glass passivation techniques suitable for industrial environments.

Replacement Considerations

Cross-reference with other Vishay parts in the SE20FJ series for pin-compatible alternatives. Verify that any substitute maintains the 600 V reverse voltage and 1 A forward current ratings. Ensure the replacement device supports the required avalanche ruggedness if present in the original circuit design.
