SS1P4-E3/84A

Single Diodes Overview

The SS1P4-E3/84A is a Schottky rectifier manufactured by Vishay Semiconductors, designed for surface mount applications. It features a single diode configuration within the DO-220AA (SMA) package. The device supports an average forward current of 1.0 A and a repetitive peak reverse voltage of 40 V. Key electrical parameters include a maximum forward voltage of 500 mV at rated current, a surge forward current capability of 50 A, and a low reverse leakage current of 150 uA. It operates reliably across a junction temperature range from -55°C to +150°C.

Single Diodes Feature Summary

• Utilizes silicon Schottky barrier technology for high switching efficiency
• Features low forward voltage drop to minimize conduction losses
• Designed with low reverse leakage current characteristics
• Constructed in a compact surface-mount SMA package

Single Diodes Applications

• High-frequency power supply circuits
• DC-to-DC converter modules
• Free-wheeling rectification in low-voltage systems
• Polarity protection in electronic devices

Single Diodes Procurement Notes

Verify the specific ordering suffix against official Vishay documentation to confirm package type and tape-and-reel specifications. Ensure compliance with RoHS directives and REACH SVHC requirements as stated in the manufacturer's datasheet. Cross-reference the full part number to distinguish between standard and automotive-grade variants if applicable.

Single Diodes Selection Notes

Select this component for designs requiring efficient rectification at low voltages and moderate currents. The 40 V rating suits 5 V and 12 V systems. Consider the thermal performance within the SMA package for high-density layouts. Verify that the 1 A current rating meets the continuous load requirements without excessive derating.

Single Diodes Part Context

This component belongs to the SS1P series of surface mount Schottky rectifiers. It shares the same electrical profile as the SS1P4 but may differ in packaging or trailing digits indicating specific handling or testing criteria. It serves as a modern replacement for through-hole rectifiers in space-constrained PCB designs.

Single Diodes Replacement Considerations

Direct substitutes include the SS1P4-E3/9AT and SS1P4HM3/84A. Verify pinout compatibility and ensure the alternative part meets the same 40 V and 1 A ratings. Check for identical package dimensions to maintain mechanical fit.
