Overview
The B140B-13 is a surface mount Schottky barrier rectifier manufactured by Diodes Incorporated. It features a single diode configuration in an SMB (DO-214AA) package. The device supports a maximum average forward rectified current of 1.0 A and a repetitive peak reverse voltage of 40 V. Key electrical parameters include a maximum forward voltage of 0.5 V at 1 A, a maximum reverse leakage current of 0.5 mA at rated voltage, and a non-repetitive peak forward surge current rating of 30 A.
Feature Summary
- Guard ring die construction provides protection against transient voltage events.
- Ultra-low leakage current characteristics contribute to high efficiency.
- Low power loss design optimizes thermal performance.
- Surge overload capability handles high peak current pulses.
Applications
- Low voltage, high frequency inverters
- Free wheeling applications
- Polarity protection circuits
Procurement Notes
Verify the specific datasheet revision when sourcing, as manufacturing updates may occur. Confirm RoHS compliance status for environmental requirements. Ensure the SMB package footprint matches the PCB layout. Check for any lead-free finish specifications if required by assembly processes. Validate that the 40V rating meets the circuit's peak inverse voltage demands.
Selection Notes
Select this component for circuits requiring efficient rectification with low forward voltage drop. The 1A current rating suits moderate power applications. The SMB package offers a compact solution for surface mount designs. Consider the 40V reverse voltage limit to ensure adequate headroom. Evaluate thermal management needs based on the 0.5V forward voltage characteristic.
Part Context
This part belongs to the B1xxB series of Schottky barrier rectifiers from Diodes Incorporated. These devices are designed for general-purpose rectification in consumer and industrial electronics. The series utilizes silicon technology for reliable operation across standard temperature ranges. The SMB package is common for small signal and medium current applications.
Replacement Considerations
Compatible substitutes within the same family include B140BQ-13-F and B140AE-13. Verify pinout compatibility and package dimensions before substitution. Ensure replacement parts meet or exceed the 40V reverse voltage and 1A current ratings. Check for equivalent forward voltage and leakage current specifications.
