B140HB-13

Overview

The B140HB-13 is a surface mount Schottky barrier rectifier manufactured by Diodes Incorporated. It features a single element silicon construction housed in an SMB (DO-214AA) plastic case with two terminals. The device supports a peak repetitive reverse voltage of 40V and provides an average rectified output current of 1.0A at a terminal temperature of 115°C. It withstands non-repetitive peak forward surge currents up to 45A for 8.3ms or 430A for 5μs. Electrical characteristics include a maximum forward voltage drop of 0.70V at 2.0A and 125°C, and a leakage current of 4.0mA at 40V and 100°C.

Feature Summary

• Guard ring die construction designed for transient protection
• Low power loss and high efficiency operation
• Ultra-low leakage current performance
• Ideally suited for automated assembly processes

Applications

• Low voltage high frequency inverters
• Free wheeling applications
• Polarity protection circuits

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging details. The standard datasheet indicates the -13-F variant utilizes tape and reel packaging with a quantity of 3000 units per reel. Confirm compliance requirements such as RoHS status and green molding compound specifications directly from the official product data sheet prior to procurement.

Selection Notes

Select this component for designs requiring a 40V blocking capability and 1.0A continuous current handling in a compact SMB package. Ensure thermal management accounts for the junction-to-terminal thermal resistance of 36°C/W. Verify that the operating environment remains within the specified -55°C to +150°C range and that surge current demands do not exceed the rated 45A limit for standard half-sine wave conditions.

Part Context

This component belongs to the B140HB series of surface mount Schottky barrier rectifiers produced by Diodes Incorporated. The series is engineered for general-purpose rectification in space-constrained printed circuit board layouts. The SMB package offers a balance between current carrying capacity and footprint size compared to smaller signal diode packages.

Replacement Considerations

Direct replacements must match the 40V reverse voltage, 1.0A average current, and SMB package dimensions. Verify that substitute components maintain equivalent forward voltage characteristics and leakage current limits to ensure circuit performance parity.
