B340A-E3/61T

Overview

The B340A-E3/61T is a Schottky rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive reverse voltage of 40 V and an average forward rectified current of 3 A. The device utilizes the DO-214AC (SMA) surface-mount package. Key electrical parameters include a maximum forward voltage of 550 mV at 3 A and a reverse leakage current of 500 µA at 40 V. The component operates within a junction temperature range of -65°C to 150°C.

Feature Summary

• Schottky barrier technology for low forward voltage drop
• Surface-mount construction in DO-214AC package
• High thermal stability with elevated operating temperature rating

Applications

• DC-DC converters
• Free-wheeling diodes
• Polarity protection circuits

Procurement Notes

Verify the specific suffix /61T against official Vishay documentation to confirm tape and reel specifications. Ensure compatibility with automated assembly processes. Cross-reference datasheet revisions to confirm RoHS compliance status and manufacturing origin details before finalizing procurement orders.

Selection Notes

Select this component when a 40 V reverse voltage rating and 3 A continuous current capacity are required in a compact SMA footprint. Consider the 550 mV forward voltage characteristic for efficiency optimization. Verify that the DO-214AC package dimensions align with the target PCB layout constraints.

Part Context

This part belongs to the B340A-E3 series of Schottky rectifiers from Vishay. It shares the core electrical characteristics of the B340 family but is distinguished by its specific packaging and trailing configuration indicated by the /61T suffix. It serves as a surface-mount alternative to through-hole variants like the SB340.

Replacement Considerations

B340A-E3/5AT is documented as an alias or variant within the same product line.
