Overview
The B140-E3/61T 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 +150 °C. The component is housed in an SMA (DO-214AC) package with matte tin-plated terminals.
Feature Summary
- Guardring structure provides overvoltage protection
- Low forward voltage drop for high efficiency
- High surge current capability
- Meets MSL level 1 per J-STD-020
Applications
- Low voltage, high frequency inverters
- Freewheeling applications

- Polarity protection circuits
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging quantity and delivery mode. Confirm RoHS compliance status and material categorization requirements prior to procurement. Ensure the selected variant matches the required thermal resistance and operating temperature specifications for the intended application environment.
Selection Notes
Select this component for applications requiring low power losses and high efficiency in compact designs. The SMA (DO-214AC) package is suitable for automated placement processes. Consider the 30 A peak forward surge current rating when designing circuits subject to transient loads. Validate thermal performance based on the specified typical thermal resistance values.
Part Context
This part belongs to the B1xx-E3 series of surface-mount Schottky barrier rectifiers from Vishay. The series includes variants with different reverse voltage ratings ranging from 20 V to 60 V. All members share similar mechanical characteristics and are designed for use in low voltage, high frequency applications requiring efficient rectification.
Replacement Considerations
Cross-reference with other B140 variants such as B140-E3/5AT for different reel quantities. Verify compatibility with alternative SMA packaged Schottky diodes if sourcing constraints exist.
