Overview
The B140B-13-F 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 1.0A and a repetitive peak reverse voltage of 40V. Key electrical parameters include a maximum DC reverse leakage current of 5mA at rated voltage, a maximum non-repetitive peak forward surge current of 30A, and a maximum forward voltage drop of 0.5V at 1.0A. It operates within a junction temperature range of -65°C to +150°C.
Feature Summary
- Guard ring die construction provides enhanced transient protection capabilities
- Ultra-low leakage current characteristics contribute to high efficiency operation
- Low power loss design optimizes thermal performance in compact form factors
Applications
- Free wheeling applications in low voltage circuits
- Polarity protection for sensitive electronic loads
- High frequency inverters requiring fast switching speeds
Procurement Notes
Verify the specific datasheet revision number against your design requirements to ensure parameter consistency. Confirm that the SMB package dimensions align with your PCB footprint constraints. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the operating temperature range meets your system's thermal profile expectations.
Selection Notes
Select this component when a 40V reverse voltage rating and 1A continuous current capacity are required in a surface mount format. Consider the ultra-low leakage specification for battery-powered or high-efficiency designs. Evaluate the SMB package size relative to available board space compared to larger through-hole alternatives.
Part Context
This part belongs to the B1xxB series of Schottky rectifiers from Diodes Incorporated. The series offers various voltage ratings while maintaining consistent current handling and package styles. It serves as a standard solution for general-purpose rectification tasks where speed and efficiency are prioritized over high voltage blocking capability.
Replacement Considerations
Direct substitutes include other 40V 1A Schottky diodes in the SMB package such as the B140 from different manufacturers. Verify pinout compatibility and thermal resistance values before substitution.
