AR1FJ-M3/H

Overview

The AR1FJ-M3/H is a surface-mount fast avalanche rectifier manufactured by 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 utilizes a glass-passivated pellet chip junction for high reliability and low leakage current. Key electrical parameters include a maximum reverse recovery time of 140 ns, a typical junction capacitance of 12.6 pF at 4.0 V and 1 MHz, and a non-repetitive avalanche energy capability of 20 mJ at 1.0 A. It operates within a temperature range of -55 °C to +175 °C.

Feature Summary

• Fast switching characteristics suitable for high-frequency applications
• Avalanche-rated capability for inductive load switching
• Glass passivated junction structure for enhanced reliability
• Low profile SMF (DO-219AB) package ideal for automated placement

Applications

• General purpose rectification in power supplies
• Freewheeling diodes for consumer electronics
• Inverter and converter circuits
• Automotive electronic systems

Procurement Notes

Verify the specific ordering suffix to confirm qualification status. The base part number without the 'HM3' suffix indicates standard compliance. Confirm that the 'M3' suffix denotes halogen-free and RoHS-compliant materials. Ensure the delivery mode matches the required packaging quantity, such as tape and reel options. Cross-reference the document revision date with the manufacturing batch to ensure data currency.

Selection Notes

Select this component when a 600 V blocking voltage is required for single-phase rectification. The 140 ns reverse recovery time makes it suitable for higher frequency switching compared to standard recovery diodes. Consider the thermal resistance values for heat dissipation planning in free-air or mounted conditions. Verify that the operating junction temperature will not exceed the maximum rated limit during peak load scenarios.

Part Context

This device belongs to the eSMP series of surface-mount fast avalanche rectifiers from Vishay. It shares the same mechanical outline and general feature set with other variants in the AR1F family, differentiated primarily by their voltage ratings. The AR1FJ variant specifically targets the 600 V application segment within this product line.

Replacement Considerations

Compatible substitutes within the same Vishay family include AR1FK-M3/H (800 V) and AR1FM-M3/H (1000 V), provided the voltage margin allows. Other manufacturers offering DO-219AB packaged fast recovery rectifiers may serve as alternatives if pin compatibility and electrical ratings are matched.
