Overview
The B140-M3/5AT is a surface-mount Schottky barrier rectifier manufactured by Vishay General Semiconductor. It features a maximum average forward rectified current of 1.0 A and a maximum repetitive peak reverse voltage of 40 V. The device utilizes an SMA (DO-214AC) case configuration with matte tin-plated leads. Electrical characteristics include a maximum instantaneous forward voltage of 0.75 V at 1.0 A and a peak forward surge current rating of 30 A. Thermal resistance values are specified as 95 °C/W junction-to-ambient and 30 °C/W junction-to-lead.
Feature Summary
- Guardring structure provides overvoltage protection capabilities
- Low forward voltage drop contributes to high efficiency and low power losses
- High surge capability supports robust performance under transient conditions
- Molding compound meets UL 94 V-0 flammability rating
Applications
- Low voltage, high frequency inverters
- Freewheeling applications
- DC/DC converters
- Polarity protection circuits
Procurement Notes
Verify the specific ordering suffix /5AT corresponds to the 13-inch diameter plastic tape and reel packaging containing 7500 units per base quantity. Confirm RoHS compliance status and material categorization definitions via official Vishay documentation before finalizing procurement specifications.
Selection Notes
Select this component for designs requiring a single Schottky rectifier in an SMA package. Ensure the operating junction temperature range aligns with the application's thermal environment. Validate that the 40 V reverse voltage rating exceeds the circuit's peak reverse voltage requirements.
Part Context
This part belongs to the B1xx-M3 series of surface-mount Schottky barrier rectifiers. The series includes variants with different reverse voltage ratings ranging from 20 V to 60 V. All devices share the same SMA (DO-214AC) mechanical outline and general electrical architecture defined in document number 89926.
Replacement Considerations
Direct substitutes within the same series include B120-M3/5AT, B130-M3/5AT, B150-M3/5AT, and B160-M3/5AT. These alternatives maintain identical mechanical dimensions and current ratings while offering different maximum repetitive peak reverse voltage levels.
