B340LB-M3/52T

Single Diodes Overview

The B340LB-M3/52T is a surface-mount Schottky barrier rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 40 V and a continuous forward current rating of 3 A. The device utilizes the DO-214AA (SMA) package with two pins. Key electrical characteristics include a maximum forward voltage of 450 mV at rated current, a peak non-repetitive forward surge current capability of 100 A, and a maximum reverse leakage current of 40 mA. The component operates within a temperature range from -65 °C to +150 °C junction temperature.

Single Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and compliance status. Ensure the requested part number matches the exact electrical ratings required for the target circuit design. Cross-reference the manufacturer code with authorized distribution channels to guarantee authenticity and traceability of the semiconductor components.

Single Diodes Selection Notes

Select this component when a low forward voltage drop is critical for system efficiency. The 3 A current rating suits moderate power applications requiring fast recovery characteristics. Verify that the DO-214AA footprint aligns with the printed circuit board design constraints. Confirm thermal management requirements are met given the specified operating temperature limits.

Single Diodes Part Context

This device belongs to the B340LB-E3/M3 series of Schottky rectifiers from Vishay. The M3 suffix typically indicates lead-free termination and RoHS compliance. The LB variant specifies the SMA (DO-214AA) surface-mount package configuration. This series is engineered for general-purpose rectification tasks where speed and low loss are prioritized over high voltage blocking capabilities.

Single Diodes Replacement Considerations

Direct substitutes include B340LB-E3/52T and B340A-E3/5AT. Verify pinout compatibility and thermal resistance values before substitution. Ensure the alternative part meets the same 40 V and 3 A specifications.
