- Controlled avalanche characteristics for robust transient handling
- Very low profile design suitable for automated placement
- High forward surge capability with fast reverse recovery
Applications
- Lighting circuits
- High frequency rectification
- Freewheeling applications in switching mode converters
- Inverter systems for consumer, computer, automotive, and telecommunication equipment
Procurement Notes
Verify the specific ordering code against the datasheet to ensure correct packaging and qualification levels. The /87A suffix indicates a 6500-unit reel in a 13-inch plastic tape. Confirm that the base part number matches the required voltage rating and that the M3 suffix aligns with halogen-free and RoHS compliance requirements for the intended manufacturing process.
Selection Notes
Select this component when a high-voltage ultrafast rectifier with avalanche capability is required in a compact surface-mount form factor. The TO-277A package offers a low profile ideal for space-constrained designs. Ensure the application demands a 600 V reverse voltage rating and can accommodate the specified thermal resistance values for proper heat dissipation during operation.
Part Context
This device belongs to the AU3PD, AU3PG, and AU3PJ family of ultrafast avalanche rectifiers. All variants share identical mechanical dimensions and electrical characteristics except for the maximum repetitive peak reverse voltage, which varies by model. The AU3PJ specifically provides the highest voltage rating within this three-part series.
Replacement Considerations
Direct substitutes include AU3PD-M3/87A and AU3PG-M3/87A from the same manufacturer, provided the lower voltage ratings are acceptable for the circuit design. Verify pinout compatibility and thermal performance before substitution.
