AU3PDHM3/86A

Overview

The AU3PDHM3/86A is a surface-mount Avalanche diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum DC reverse voltage of 200 V and an average forward current rating of 1.7 A. The device utilizes the TO-277A (SMPC) package with a junction temperature range of -55°C to 150°C. It is RoHS compliant and classified under the eSMP® series, designed for robust transient protection applications.

Feature Summary

• Utilizes Avalanche technology for high-reliability transient suppression
• Designed in a compact surface-mount TO-277A (SMPC) package
• Capable of handling peak pulse currents up to 31 A

Applications

• General circuit protection
• Transient voltage suppression
• Electronic component safeguarding

Procurement Notes

Verify the specific suffix /86A corresponds to the required tape-and-reel packaging configuration. Confirm that the 200V reverse voltage and 1.7A current ratings align with the target circuit's operational requirements. Ensure compatibility with the TO-277A footprint during PCB layout validation.

Selection Notes

Select this component when a surface-mount Avalanche diode is required for circuits operating up to 200V reverse bias. The TO-277A package offers a balance between thermal performance and board space efficiency. Consider the 1.7A average current limit and 31A peak pulse capability when sizing for expected transient events.

Part Context

This part belongs to Vishay's eSMP® series of surface-mount power diodes. It shares the TO-277A (SMPC) form factor with other devices in the lineup, such as the SS3P6L-M3/86A and VS-6ESH02HM3/86A, facilitating standardized footprint design across different diode technologies within the same product family.
