B140S1F-7

Overview

The B140S1F-7 is a 1.0A Schottky Barrier Rectifier manufactured by Diodes Incorporated, housed in the SOD123F surface-mount package. It features a peak repetitive reverse voltage of 40V and an average rectified output current of 1A. The device exhibits a maximum forward voltage drop of 0.5V at 1A and 25°C, with a non-repetitive peak forward surge current rating of 30A. Operating temperatures range from -55°C to +150°C.

Feature Summary

• Provides reduced low forward voltage drop for better efficiency and cooler operation
• Features reduced high-temperature reverse leakage to increase reliability against thermal runaway failure
• Constructed with molded plastic green molding compound that is UL flammability classified as 94V-0

Applications

• Boost Diode
• Blocking Diode
• Recirculating Diode

Procurement Notes

Verify the specific ordering suffix '-7' corresponds to the 3,000 units per tape and reel packaging configuration documented in the official datasheet. Confirm that the component meets RoHS compliance standards and is halogen and antimony free as specified by the manufacturer's definitions for green devices.

Selection Notes

Select this component for general rectification applications requiring low forward voltage and excellent reverse leakage stability at elevated temperatures. Ensure the design accommodates the 40V peak repetitive reverse voltage limit and the 1A average rectified output current capability under the specified thermal conditions.

Part Context
