Overview
The Vishay AR4PJHM3/86A is a fast switching avalanche surface-mount rectifier in the eSMP series. It features a single diode configuration within an SMPC (TO-277A) package. The device supports a maximum repetitive peak reverse voltage of 600 V and a maximum DC forward current of 4.0 A. Key electrical characteristics include a typical reverse recovery time of 140 ns, a non-repetitive avalanche energy rating of 20 mJ, and a peak forward surge current capability of 65 A. The component operates across a junction temperature range of -55 °C to +175 °C.
Feature Summary
- Features controlled avalanche characteristics for robust performance under transient conditions.
- Utilizes glass passivated pellet chip junction technology for enhanced reliability.
- Designed with a very low profile to facilitate automated placement processes.
- Complies with JESD 201 class 2 whisker test requirements.
Applications
- Fast switching rectification in power supplies
- Freewheeling diodes for consumer electronics
- Inverter and converter circuits
- Automotive lighting systems
Procurement Notes
Verify that the ordering code includes the HM3 suffix to confirm AEC-Q101 automotive qualification status. Ensure the base part number matches the specific voltage rating required for the application. Confirm the packaging code corresponds to the desired reel size and delivery mode before finalizing procurement specifications.
Selection Notes
Select this component when high-frequency switching and avalanche ruggedness are required in a compact surface-mount form factor. The 600 V rating distinguishes it from lower voltage variants like the AR4PD or AR4PG. Consider the thermal resistance values and derating curves for proper heat dissipation design in high ambient temperature environments.
Part Context
This device belongs to the AR4P family of fast switching avalanche rectifiers manufactured by Vishay General Semiconductor. It shares the same mechanical SMPC (TO-277A) footprint as other members of the series, allowing for standardized board layouts across different voltage ratings within the product line.
