MBR140SFT1G Description

Short technical summary and product information.

This device is a Schottky barrier power rectifier utilizing a large area metal-to-silicon diode. It is designed for low voltage, high frequency rectification, freewheeling, and polarity protection in surface mount applications where compact size and weight are critical.

 

Key electrical specifications include a maximum reverse voltage of 40V, an average forward current of 1.0A at TL=112°C, and a typical forward voltage drop of 550mV at 1A forward current. The device can handle a peak repetitive forward current of 2.0A (square wave, 100 kHz). Operating junction temperature is rated up to 125°C.

 

The SOD-123FL package is designed for optimal automated board assembly and features a cathode band for polarity identification. It is epoxy molded, meets UL 94 V-0 flammability rating, and is RoHS compliant, Pb-free, and halogen free. The device also includes a guardring for stress protection.
