Overview
The AR1FJHM3/I is a surface-mount fast avalanche rectifier manufactured by Vishay General Semiconductor. It features a glass passivated pellet chip junction and operates in the SMF (DO-219AB) package. The device supports a maximum repetitive peak reverse voltage of 600 V and an average forward current of 1.0 A. Key electrical parameters include a maximum reverse recovery time of 140 ns, a typical junction capacitance of 12.6 pF at 4 V and 1 MHz, and a non-repetitive avalanche energy rating of 20 mJ at IAS = 1.0 A. It is qualified to AEC-Q101 standards for automotive applications.
Feature Summary
- Fast switching capability designed for high-frequency operation
- Avalanche rated for robust performance under transient conditions
- Glass passivated junction ensures low reverse leakage current
- Low profile package optimized for automated placement
Applications
- General purpose rectification in power supplies
- Freewheeling diodes in inverters and converters
- Automotive electronic systems
- Telecommunication equipment
Procurement Notes
Verify that the ordering suffix /I corresponds to the 13-inch diameter plastic tape and reel packaging configuration as specified in the datasheet. Confirm the base part number AR1FJ aligns with the required 600 V reverse voltage rating. Ensure the HM3 suffix indicates compliance with halogen-free and RoHS requirements alongside AEC-Q101 qualification for automotive use cases.
Selection Notes
Select this component when a 600 V blocking capability is required in a compact surface-mount form factor. The 140 ns reverse recovery time makes it suitable for high-frequency switching applications. Consider the 20 mJ avalanche energy rating if the circuit design involves potential inductive load switching or transient voltage spikes exceeding standard ratings.
Part Context
This device belongs to the AR1FD, AR1FG, AR1FJ, AR1FK, and AR1FM series of surface-mount fast avalanche rectifiers. All variants share the same SMF (DO-219AB) package and general mechanical characteristics but differ in their maximum repetitive peak reverse voltage ratings, which range from 200 V to 1000 V across the family.
Replacement Considerations
Direct substitutes within the same Vishay series include AR1FKHM3/I (800 V) and AR1FGHM3/I (400 V), provided the voltage ratings accommodate the specific circuit requirements. Verify that any replacement maintains the DO-219AB footprint and similar thermal resistance characteristics.
