Overview
The B140-E3/5AT is a silicon Schottky barrier rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum average forward rectified current of 1 A and a maximum repetitive peak reverse voltage of 40 V. The device utilizes the DO-214AC (SMA) surface-mount package. Key electrical characteristics include a low forward voltage drop of 500 mV at 1 A and a maximum non-repetitive peak surge forward current capability. The component is designed for high-efficiency power conversion applications requiring fast switching speeds.
Feature Summary
- Schottky barrier technology ensures ultra-fast switching and minimal reverse recovery charge
- Low forward voltage drop contributes to improved system efficiency and reduced heat generation
- Plastic material complies with UL flammability classification 94V-0 standards
Applications
- High-frequency DC-to-DC converters
- Free-wheeling diodes in PWM circuits
- Polarity protection applications
Procurement Notes
Verify the specific suffix 'E3' confirms RoHS compliance and halogen-free status as per Vishay documentation. Confirm the '5AT' packaging designation matches the required reel quantity for automated assembly processes. Ensure the DO-214AC footprint aligns with the target PCB layout specifications before finalizing procurement orders.
Selection Notes
Select this component when designing circuits that require low forward voltage loss at moderate currents up to 1 A. The 40 V reverse voltage rating suits low-voltage power supply outputs. Consider the thermal derating requirements for the SMA package in confined spaces compared to through-hole alternatives.
Part Context
This part belongs to the Bxx series of Vishay Schottky rectifiers, which are optimized for general-purpose low-voltage rectification. The E3 suffix indicates environmental compliance, while the DO-214AC package provides a compact solution for space-constrained surface-mount designs.
Replacement Considerations
Cross-reference with other Vishay SMA Schottky variants such as the B130 or B150 if voltage ratings differ. Verify pinout compatibility with equivalent packages from other manufacturers before substitution.
