Overview
The AR1PJHM3/84A is a surface mount fast avalanche rectifier from Vishay General Semiconductor. It features a maximum repetitive peak reverse voltage of 600 V and an average forward current rating of 1.0 A. The device supports a peak forward surge current of 25 A and exhibits a maximum reverse recovery time of 120 ns. Operating junction temperatures range from -55 °C to +175 °C, with a typical thermal resistance of 15 °C/W from junction to mount.
Feature Summary
- Fast switching capability for high efficiency applications
- Glass passivated pellet chip junction construction
- Qualified for automotive grade environments per AEC-Q101 standards
- Low profile design suitable for automated placement
Applications
- Freewheeling diodes in consumer electronics
- Power supply rectification circuits
- Inverter and converter systems
- Telecommunication equipment power stages
Procurement Notes
Verify the specific suffix HM3 indicates automotive grade compliance and halogen-free composition. Confirm the package code matches SMP (DO-220AA) requirements. Ensure ordering quantities align with standard reel sizes. Validate RoHS and REACH compliance status against current regulatory updates before finalizing procurement specifications.
Selection Notes
Select this component when high-speed rectification is required alongside avalanche energy handling capabilities. The 600 V rating suits medium-voltage DC-DC conversion tasks. Verify that the 1.0 A continuous current meets system load demands. Consider the low thermal resistance for efficient heat dissipation in compact PCB layouts without excessive copper pad areas.
Part Context
This part belongs to the eSMP series of surface mount fast avalanche rectifiers. It shares the SMP package form factor with other variants like AR1PD and AR1PM but offers distinct voltage ratings. The HM3 designation differentiates it as an automotive-grade product compared to commercial M3 versions within the same family.
Replacement Considerations
AR1PJ-M3/84A serves as the commercial grade equivalent. AR1PKHM3/84A provides higher voltage tolerance at 800 V. AR1PGHM3/84A offers lower voltage at 400 V. All share identical packaging and pin configurations.
