AU3PDHM3_A/I

Overview

The AU3PDHM3_A/I is a surface mount transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor. It features a maximum DC reverse standoff voltage of 200V and is designed to protect sensitive electronic circuits from voltage transients up to this level. The component utilizes the TO-277A (SMPC) package, providing a compact form factor suitable for automated assembly processes in modern electronics manufacturing.

Feature Summary

• Provides robust protection against voltage transients up to 200 volts
• Utilizes compact surface mount TO-277A packaging for space-constrained designs

Applications

• Protection of sensitive electronics from voltage spikes in industrial devices
• Transient suppression in consumer electronic equipment
• Circuit safeguarding in automotive applications

Procurement Notes

Verify the specific datasheet version for the AU3PDHM3_A/I to confirm exact clamping voltages and pulse current ratings, as these parameters are critical for circuit design. Ensure that the TO-277A footprint matches the PCB layout requirements. Cross-reference with official Vishay documentation to validate RoHS compliance status and thermal characteristics before finalizing procurement specifications.

Selection Notes

Select this component when a 200V standoff voltage rating is required for transient protection in surface mount applications. The TO-277A package offers a balance between power handling capability and board space efficiency. Consider the peak pulse current capacity relative to the expected transient energy levels in the target application environment to ensure adequate protection margins.

Part Context

This device belongs to Vishay's general semiconductor diode division portfolio, specifically within the TVS diode category. It is part of a series designed for high-reliability transient suppression in various electronic systems. The SMPC package variant provides standardized mounting options compatible with industry-standard surface mount technology assembly lines.

Replacement Considerations

Check for parameter-equivalent alternatives such as the AU3PDHM3/87A if supply constraints exist. Verify that any substitute maintains the same 200V reverse voltage rating and compatible TO-277A or equivalent package dimensions to ensure mechanical and electrical interchangeability without redesigning the host circuit.
