V8P8HM3_A/H

Single Diodes Overview

The V8P8HM3_A/H is an AEC-Q101 qualified high current density surface mount TMBS rectifier from Vishay. It features a single circuit configuration in an SMPC (TO-277A) package. Key electrical parameters include a maximum repetitive peak reverse voltage of 80 V and a maximum average forward rectified current of 8.0 A. The device exhibits ultra-low forward voltage characteristics, with a typical value of 0.42 V at 4 A and 0.54 V at 8 A when the junction temperature is 125 °C. Peak forward surge current capability is rated at 140 A.

Single Diodes Feature Summary

• Utilizes Trench MOS Schottky technology to achieve very low forward voltage drop and reduced power losses for high efficiency operation.
• Features a compact mechanical profile with a typical height of 1.1 mm, making it ideal for automated placement processes.
• Complies with automotive reliability standards through AEC-Q101 qualification and meets JESD 201 class 2 whisker test requirements.

Single Diodes Applications

Single Diodes Procurement Notes

Verify that the specific ordering code matches the required automotive grade and revision suffix. Confirm compliance with halogen-free and RoHS directives as specified for the HM3 variant. Ensure thermal management designs account for the stated junction-to-ambient resistance values under free air or PCB mounting conditions.

Single Diodes Selection Notes

Select this component for designs requiring robust performance in demanding power-conversion environments. The low forward voltage minimizes conduction losses, while the high surge current rating provides resilience against transient loads. Verify that the operating junction temperature remains within the -40 °C to +150 °C range during application.

Single Diodes Part Context
