AU2PGHM3/87A

Overview

The AU2PGHM3/87A is a surface-mount avalanche diode manufactured by Vishay General Semiconductor - Diodes Division. It features a TO-277A (SMPC) package and belongs to the eSMP series. The device is rated for a maximum DC reverse voltage of 400 V and an average forward current of 1.6 A. It exhibits a forward voltage of 1.9 V at 2 A. The component is RoHS compliant and lead-free.

Feature Summary

• Engineered with avalanche breakdown characteristics for robust transient protection applications
• Utilizes the eSMP surface-mount technology for compact circuit board integration
• Constructed with lead-free materials ensuring compliance with environmental directives

Applications

• Transient voltage suppression in electronic circuits
• Protection against electrostatic discharge events
• Overvoltage protection in power supply inputs

Procurement Notes

Verify the specific suffix /87A corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the 400 V rating aligns with the system's peak inverse voltage requirements. Ensure the TO-277A footprint matches the designated PCB land pattern. Check for any updated environmental declarations or material composition statements from the manufacturer before finalizing procurement specifications.

Selection Notes

Select this component when a surface-mount avalanche diode with a 400 V blocking capability is required. The 1.6 A current rating suits moderate power dissipation needs. The TO-277A package offers a balance between thermal performance and space efficiency. Consider the forward voltage drop of 1.9 V for efficiency calculations in low-voltage systems. Verify compatibility with standard reflow soldering profiles for the SMPC package.

Part Context

This part belongs to Vishay's eSMP series of surface-mount diodes. The AU2P prefix typically denotes avalanche-rated devices within the product line. The /87A suffix indicates specific packaging and ordering information, often relating to reel quantities. These components are designed for general-purpose protection roles in consumer and industrial electronics where reliable transient handling is critical.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 400 V reverse voltage, 1.6 A current rating, and TO-277A package dimensions. Verify electrical characteristics and pinout compatibility with alternative avalanche diodes from other manufacturers.
