Description

The SBR440SB is a 4A 40V single rectifier packaged in the low-profile SMB package. Providing low VF and excellent high temperature stability, this device is ideal for use in general rectification applications such as: boost diodes, blocking diodes, and recirculating diodes.

Feature(s)

Patented SBR® technology provides an avalanche capability five times larger than Schottky diodes ensuring more rugged and reliable end applications.
Lower reverse leakage ensuring greater stability at higher temperatures.
Low forward voltage (V_F) minimizes conduction losses and improving efficiency.
Lead-Free Finish; RoHS Compliant (Notes 1 & 2)
Halogen and Antimony Free. “Green” Device (Note 3)
For automotive applications requiring specific change control (i.e. parts qualified to AEC-Q100/101/104/200, PPAP capable, and manufactured in IATF 16949 certified facilities), please contact us or your local Diodes representative. https://www.diodes.com/quality/product-definitions/
