SE30AFB-M3/6B

Single Diodes Overview

The SE30AFB-M3/6B is a single standard recovery rectifier from Vishay Semiconductors, housed in the SlimSMA (DO-221AC) surface-mount package. It features a 100 V repetitive peak reverse voltage and a 3 A average forward rectified current capability. The device exhibits a maximum forward voltage of 860 mV at rated current and a typical reverse leakage current of 10 uA. It supports a maximum surge current of 40 A and operates within a junction temperature range of -55 °C to +175 °C.

Single Diodes Feature Summary

• Standard recovery rectifier technology optimized for general-purpose switching applications
• SlimSMA surface-mount package designed for high-density PCB layouts
• High thermal stability supporting extended operating temperatures up to 175 °C

Single Diodes Applications

• General purpose rectification in power supply circuits
• Freewheeling diodes in low-voltage DC-DC converters
• Reverse polarity protection in consumer electronics

Single Diodes Procurement Notes

Verify the specific suffix designation during procurement, as variations such as /6A or /6B may indicate differences in tape-and-reel packaging or manufacturing lot codes rather than electrical performance changes. Confirm RoHS compliance status through official datasheets prior to integration into regulated assemblies.

Single Diodes Selection Notes

Select this component when a compact SMD rectifier with 100 V blocking capability and 3 A continuous current rating is required. The SlimSMA package offers a smaller footprint compared to traditional SMA cases while maintaining similar electrical characteristics suitable for space-constrained designs.

Single Diodes Part Context

This part belongs to the Vishay SE30AF series of SlimSMA rectifiers. The series provides standard recovery performance in a compact surface-mount form factor, targeting applications requiring reliable rectification in limited board space environments without sacrificing current handling capabilities.

Single Diodes Replacement Considerations

Cross-reference with other Vishay SlimSMA variants like SE30AFG-M3 for higher voltage ratings. Verify pinout compatibility and thermal resistance parameters when substituting with generic DO-221AC packages from other manufacturers.
