Overview
The B140-M3/61T 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 maximum average forward rectified current of 1.0 A. The device exhibits a maximum instantaneous forward voltage of 0.75 V at 1.0 A and a peak forward surge current capability of 30 A. It operates within a junction temperature range of -65 °C to +125 °C or +150 °C depending on the specific thermal rating. The component is housed in an SMA (DO-214AC) package.
Feature Summary
- Low power losses and high efficiency due to low forward voltage drop
- Guardring structure provides overvoltage protection
- High surge current capability for robust operation
- Meets MSL level 1 per J-STD-020 with LF maximum peak of 260 °C
Applications
- Low voltage, high frequency inverters
- Freewheeling applications
- DC/DC converters
- Polarity protection circuits
Procurement Notes
Verify the complete part number including the suffix /61T to confirm the 1800-unit tape and reel delivery mode. Ensure the base part number B140-M3 matches the required 40 V reverse voltage and 1.0 A current ratings. Confirm RoHS compliance and commercial grade classification as specified in the ordering information section of the datasheet.
Selection Notes
Select this component for designs requiring a single circuit configuration in an SMA package. Consider the 30 A peak forward surge current for transient handling. Verify that the operating junction temperature range meets the application's thermal requirements. Note that these devices are not AEC-Q101 qualified for automotive environments.
Part Context
This part belongs to the B1xx-M3 series of surface-mount Schottky barrier rectifiers from Vishay. The series includes variants with reverse voltages ranging from 20 V to 60 V. All members share the same SMA (DO-214AC) case and mechanical data, differing primarily in their maximum repetitive peak reverse voltage ratings.
Replacement Considerations
Compatible substitutes within the same Vishay series include B120-M3/61T, B130-M3/61T, B150-M3/61T, and B160-M3/61T. These parts share identical packaging and current ratings but offer different reverse voltage capabilities.
