Overview
The B140WS-7-2477 is a Schottky barrier rectifier manufactured by Diodes Incorporated. It features a repetitive peak reverse voltage (Vrrm) of 40V and an average forward rectified current (Io) of 1A. The device is housed in a surface-mount SOD-323 package, also identified as SC-76. This component is engineered for high-efficiency power conversion applications requiring low forward voltage drop and fast switching characteristics.
Feature Summary
- Schottky barrier construction for low forward voltage drop
- Surface mount design suitable for automated assembly
- Fast switching capability for high-frequency operation
Applications
- DC-DC converters
- Power supply circuits
- Reverse polarity protection
Procurement Notes
Verify the specific suffix -2477 against the manufacturer's official datasheet to confirm packaging details and marking codes. Ensure compatibility with standard SOD-323 footprint requirements during PCB layout. Cross-reference part numbers with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a compact surface-mount solution is required for low-voltage, high-current rectification. The SOD-323 package offers space efficiency compared to through-hole alternatives. Consider thermal management requirements based on the expected forward current and ambient operating conditions.
Part Context
This part belongs to the B140WS series of Schottky rectifiers from Diodes Incorporated. The series provides various package options including SOD-323, SOD-523, and DO-214AC. The B140WS-7-2477 specifically utilizes the SOD-323 form factor, distinguishing it from higher current variants or different voltage ratings within the broader product family.
Replacement Considerations
Compatible substitutes include B140WS-7-79 and other B140WS variants sharing the SOD-323 package and 40V/1A specifications. Verify pinout compatibility and thermal performance before substitution.
