B140AF-13

Overview

The B140AF-13 is a 1.0A Schottky Barrier Rectifier from Diodes Incorporated, housed in an SMAF surface-mount package. It features a maximum repetitive reverse voltage of 40V and a forward current rating of 1A. The device exhibits a low forward voltage drop of 0.5V maximum at 25°C and maintains excellent reverse leakage stability at elevated temperatures. Operating temperature ranges from -55°C to +150°C.

Feature Summary

• Low forward voltage drop for improved efficiency
• Excellent high-temperature reverse leakage stability
• Increased reliability against thermal runaway failure

Applications

• Boost diode circuits
• Blocking diode applications
• Recirculating diode configurations

Procurement Notes

Verify the specific ordering suffix '-13' corresponds to the tape and reel packaging configuration as documented by Diodes Incorporated. Confirm that the SMAF case material meets UL flammability classification requirements for your assembly process. Ensure compliance with RoHS directives and halogen-free specifications during procurement validation.

Selection Notes

Select this component for general rectification tasks requiring low power loss and cooler operation. The SMAF package provides a compact footprint suitable for space-constrained designs. Evaluate thermal resistance characteristics when designing heat dissipation strategies for continuous operation near maximum ratings.

Part Context

This part belongs to the B120AF-B140AF series of Schottky barrier rectifiers manufactured by Diodes Incorporated. The series offers varying reverse voltage ratings while maintaining consistent current handling capabilities. These devices are designed to replace standard silicon rectifiers where lower forward voltage and faster switching speeds are required.
