B340LB-E3/52T

Overview

The B340LB-E3/52T is a high current density surface-mount Schottky rectifier manufactured by Vishay General Semiconductor. It utilizes a Guardring structure for overvoltage protection and is housed in a low-profile SMB (DO-214AA) package. The device features a maximum average forward rectified current of 3.0 A and a repetitive peak reverse voltage of 40 V. Key electrical characteristics include a typical forward voltage drop of 0.34 V at 3.0 A, a peak forward surge current rating of 100 A, and a maximum operating junction temperature of 150 °C.

Feature Summary

Guardring structure provides enhanced overvoltage protection capabilities
Very low forward voltage drop ensures high efficiency and reduced power loss
Low profile SMB package design is optimized for automated placement processes

Applications

Low voltage, high frequency inverters
Freewheeling diode applications
DC/DC converters
Polarity protection circuits

Procurement Notes

Verify the specific ordering suffix to confirm the packaging format. The /52T designation indicates a 7-inch diameter tape and reel with a base quantity of 750 units. Confirm RoHS compliance status and material categorization details through official Vishay documentation before finalizing procurement specifications.

Selection Notes

Select this component for designs requiring high current density in a compact surface-mount footprint. Ensure the application operates within the specified 40 V reverse voltage limit and 3.0 A average forward current constraints. Consider the thermal resistance characteristics when designing heat dissipation strategies for high-efficiency power conversion systems.

Part Context

This part belongs to the B340LB series of high current density surface-mount Schottky rectifiers from Vishay. The series is engineered for applications demanding low power loss and high surge capability. The E3 suffix denotes a commercial grade product that is RoHS compliant and lead-free, adhering to environmental directives.

Replacement Considerations

Compatible substitutes within the same family include B340LB-E3/5BT, which shares identical electrical specifications but utilizes a 13-inch diameter tape and reel with a base quantity of 3200 units.
