Overview
The AU1PKHM3/84A is a surface-mount rectifier manufactured by Vishay General Semiconductor - Diodes Division. It belongs to the AU1PK series and utilizes the eSMP package, which corresponds to the DO-220AA (SMP) footprint. The device is designed for high-speed switching applications with an ultrafast recovery characteristic. It features a maximum repetitive peak reverse voltage of 800 V and supports a continuous forward current of 1.0 A. The component is qualified under the AEC-Q101 standard for automotive electronics reliability.
Feature Summary
- Ultrafast recovery speed suitable for high-frequency switching circuits
- Glass passivation for junction protection and environmental stability
- Automotive grade qualification ensuring reliability in demanding environments
Applications
- High-frequency power supply rectification
- Automotive electronic control unit power management
- DC-DC converter output stages
Procurement Notes
Verify the exact part number against official Vishay documentation to confirm the suffix /84A indicates the specific tape and reel packaging configuration. Ensure compatibility with automated pick-and-place equipment regarding the SMP package dimensions. Cross-reference the AEC-Q101 qualification status if the application requires strict automotive compliance standards.
Selection Notes
Select this component when an ultrafast rectifier with 800 V blocking capability is required in a compact surface-mount form factor. The AU1PKHM3/84A offers a balance of low reverse recovery charge and high thermal stability. Consider the DO-220AA footprint constraints and verify that the 1.0 A current rating meets the circuit's peak and average load requirements without exceeding thermal limits.
Part Context
This component is part of Vishay's eSMP family of ultrafast rectifiers. The AU1PK series is engineered for efficiency in modern power conversion topologies. The HM3 designation typically indicates lead-free construction compliant with RoHS directives. The /84A suffix specifies the specific bulk packaging or reel type provided by the manufacturer for industrial distribution.
