Overview
The B140-13 is a surface mount Schottky barrier rectifier manufactured by Diodes Incorporated. It features a single diode configuration in an SMA (DO-214AC) package. Key electrical parameters include a repetitive reverse voltage of 40 V and a forward current rating of 1 A. The maximum forward voltage is specified at 0.7 V, with a reverse current of 500 uA. It supports a forward surge current of 30 A and operates within a temperature range of -65 C to +150 C.
Feature Summary
- Utilizes Schottky barrier technology for low forward voltage drop and high efficiency.
- Designed for surface mount applications using the standard SMA package.
- Constructed from silicon material for robust performance.
Applications
- General purpose rectification in power supplies
- Free-wheeling diodes in DC-DC converters
- Polarity protection circuits
Procurement Notes
Verify the specific ordering suffix against official Diodes Incorporated documentation to confirm exact specifications. Ensure compatibility with required thermal management and mounting standards. Confirm RoHS compliance status through the manufacturer's latest product data sheets before integration into designs.
Selection Notes
Select this component for applications requiring a 40 V reverse voltage rating and 1 A continuous forward current. Consider the SMA package constraints for PCB layout. Evaluate thermal dissipation requirements based on the specified forward voltage and operating temperature limits.
Part Context
This component belongs to the family of green plastic surface mount Schottky barrier rectifiers offered by Diodes Incorporated. These devices are engineered to provide improved switching characteristics compared to standard p-n junction rectifiers, making them suitable for high-frequency applications where low loss is critical.
Replacement Considerations
Check for direct substitutes such as the B140-13-F variant which shares identical electrical ratings and packaging. Verify pinout compatibility and thermal characteristics when considering alternative manufacturers' equivalents.
