Overview
The AU3PJ-M3/86A is an ultrafast avalanche surface mount rectifier manufactured by Vishay General Semiconductor. It features a maximum repetitive peak reverse voltage of 600 V and a maximum DC forward current of 3.0 A. The device utilizes a glass passivated pellet chip junction within an SMPC (TO-277A) package. Key electrical parameters include a typical reverse recovery time of 75 ns, a peak forward surge current rating of 45 A, and a non-repetitive avalanche energy capability of 20 mJ at 2.5 A. The component operates within a temperature range of -55 °C to +175 °C.
Feature Summary
- Ultrafast reverse recovery characteristics with controlled avalanche capabilities
- Glass passivated pellet chip junction for enhanced reliability
- Low leakage current and high forward surge capability
- Designed for automated placement with a very low profile
Applications
- High frequency rectification in switching mode converters
- Freewheeling applications in inverters
- Lighting circuits
- Consumer, computer, automotive, and telecommunication equipment
Procurement Notes
Verify the specific ordering code against the datasheet to ensure correct packaging and revision levels. Confirm that the base part number suffix matches the required halogen-free and RoHS-compliant specifications. Check for AEC-Q101 qualification requirements if the application demands automotive-grade components, which utilize a distinct HM3 suffix. Validate terminal solderability standards prior to integration.
Selection Notes
Select this component when high-frequency operation and avalanche ruggedness are required. The 600 V rating suits medium-voltage rectification tasks. Ensure thermal management aligns with the specified junction-to-ambient resistance. Consider the single circuit configuration and TO-277A footprint for PCB layout compatibility. Verify that the 75 ns reverse recovery time meets the system's switching speed requirements.
Part Context
This device belongs to the eSMP series of ultrafast rectifiers from Vishay. It shares the SMPC (TO-277A) mechanical outline with other variants in the family, such as the AU3PD and AU3PG, which differ primarily in their voltage ratings. The AU3PJ specifically addresses the 600 V requirement within this standardized surface-mount form factor.
Replacement Considerations
Direct substitutes within the same voltage class include the AU3PD (200 V) and AU3PG (400 V) if lower voltage ratings are acceptable. Cross-brand replacements must match the 3.0 A current, 600 V reverse voltage, and TO-277A package dimensions. Verify equivalent reverse recovery times and avalanche energy ratings before substitution.
FAQ
What is the maximum non-repetitive avalanche energy rating?
The AU3PJ is rated for 20 mJ of non-repetitive avalanche energy at a test current of 2.5 A.
Does the component meet automotive qualification standards?
Yes, AEC-Q101 qualified versions are available, identified by the HM3 suffix in the ordering code.
What is the typical reverse recovery time?
The typical reverse recovery time is 75 ns under standard test conditions.
