AS1PD-M3/84A

Overview

The AS1PD-M3/84A is a Vishay Schottky barrier rectifier in the AS1PD series, housed in a surface-mount DO-220AA (SMP) package. It features a peak repetitive reverse voltage of 200 V and a maximum average forward rectified current of 1.5 A. The device exhibits a low forward voltage drop of 1.15 V at rated current and a peak reverse leakage current of 100 μA. Its non-repetitive peak forward surge current capacity is 30 A, with a peak reverse recovery time of 1.5 μs. Operating temperatures range from -55°C to +175°C junction temperature.

Feature Summary

• Schottky barrier technology for high switching efficiency
• Low forward voltage drop for improved system efficiency
• High thermal stability with extended operating temperature range
• Plastic material compliant with flammability standards

Applications

• DC-DC converters
• Free-wheeling diodes
• Polarity protection circuits
• Power supply output rectification

Procurement Notes

Verify the specific suffix /84A corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm RoHS compliance status via the manufacturer datasheet, as environmental declarations may vary by production batch or region. Ensure the ordering quantity aligns with standard reel sizes to avoid partial reel handling fees or inventory discrepancies during procurement.

Selection Notes

Select this component when a low-loss rectification solution is required for moderate voltage applications up to 200 V. The 1.5 A current rating suits compact power stages where space is limited. Consider the 1.5 μs recovery time against faster alternatives if switching frequencies exceed typical ranges. Verify that the DO-220AA footprint matches the PCB layout constraints and thermal management requirements of the target design.

Part Context

This part belongs to Vishay’s AS1PD series of surface-mount Schottky rectifiers. The series offers various voltage ratings within the same mechanical form factor, allowing designers to standardize footprints across different power supply designs. The M3 suffix indicates lead-free termination and RoHS compliance, aligning with modern environmental regulations for electronic components manufactured by Vishay General Semiconductor.

Replacement Considerations

Cross-reference with other Vishay AS1PD variants for different voltage ratings. Check competitor equivalents in the DO-220AA package with matching 1.5 A and 200 V specifications. Verify pinout compatibility and thermal characteristics before substituting.
