AS3PGHM3_A/I

Overview

The AS3PGHM3_A/I is a high current density standard avalanche surface mount rectifier from Vishay's eSMP series. It features a glass passivated chip junction and controlled avalanche characteristics, making it suitable for robust power applications. The device is housed in a TO-277A (SMPC) package with a typical height of 1.1 mm, ideal for automated placement. It is AEC-Q101 qualified and compliant with RoHS directives.

Feature Summary

• Glass passivated chip junction for enhanced reliability
• Controlled avalanche characteristics for rugged operation
• Low leakage current and high forward surge capability
• Very low profile design suitable for automated placement

Applications

• Automotive electronics requiring AEC-Q101 qualification
• High current density rectification circuits
• Surface mount power supply designs
• Applications demanding low profile components

Procurement Notes

Verify the specific suffix _I against the manufacturer datasheet to confirm tape and reel packaging details. Ensure the ordering part number matches the exact voltage rating within the 200V to 1000V range. Confirm RoHS compliance status and MSL level 1 requirements for your assembly process. Cross-reference the TO-277A package dimensions with your PCB footprint library.

Selection Notes

Select this component when automotive qualification and controlled avalanche behavior are required. The eSMP package offers a compact form factor compared to traditional through-hole alternatives. Consider the forward voltage drop at 3A and the reverse voltage rating relative to your circuit's peak inverse voltage. Evaluate the thermal performance within the TO-277A enclosure for your specific heat dissipation needs.

Part Context

This part belongs to Vishay's eSMP series of high current density standard avalanche rectifiers. The series includes various voltage ratings from 200V to 1000V. The AS3P designation indicates a 3A average forward current rating. The HM3 suffix denotes halogen-free construction, while the final character specifies the packaging type.

Replacement Considerations

Check for other AS3P variants with different voltage ratings or suffixes for packaging changes. Verify if alternative manufacturers offer equivalent TO-277A avalanche rectifiers with matching electrical characteristics and automotive qualifications.
