Description

The SBR440SBQ 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)
The SBR440SBQ is suitable for automotive applications requiring specific change control; this part is AEC-Q101 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities. https://www.diodes.com/quality/product-definitions/

Application(s)

Boost diodes
Blocking diodes
Recirculating diodes
