Overview
The AS1PM-M3/84A is a Super Barrier Rectifier (SBR) diode manufactured by Vishay General Semiconductor - Diodes Division. It features a peak repetitive reverse voltage of 1000 V and an average forward rectified current of 1.5 A. The device utilizes the SBR technology, which offers low forward voltage drop and fast switching characteristics without the high leakage currents associated with traditional Schottky diodes at elevated temperatures. It is housed in a surface-mount DO-220AA (SMP) package.
Feature Summary
- Super Barrier Rectifier technology for improved efficiency
- High voltage rating suitable for demanding applications
- Low thermal resistance for reliable operation
Applications
- High-frequency power supplies
- DC-DC converters
- Free-wheeling diodes in bridge circuits
Procurement Notes
Verify the specific suffix /84A corresponds to the required tape and reel packaging configuration. Confirm RoHS compliance status as indicated by the M3 suffix. Ensure the DO-220AA footprint matches the design layout. Check for any recent product change notices or lifecycle status updates from the manufacturer before finalizing procurement plans.
Selection Notes
Select this component when high voltage blocking capability is required alongside efficient rectification. The Super Barrier technology provides a compromise between the speed of Schottky diodes and the robustness of standard silicon rectifiers. Consider the thermal management requirements given the 1.5 A current rating and the specific forward voltage characteristics at operating temperatures.
Part Context
This part belongs to the AS1PD series of Super Barrier Rectifiers from Vishay. These devices are designed to replace traditional Schottky diodes in applications where higher reverse voltage ratings are needed while maintaining low forward voltage drops. The series includes various voltage ratings within the same package family.
Replacement Considerations
Direct replacements may include other Vishay SBR diodes in the AS1PD series with similar voltage and current ratings. Cross-brand equivalents should be verified against the specific forward voltage and reverse leakage specifications to ensure circuit compatibility.
