SBR140S1FQ-7 Description

Short technical summary and product information.

The SBR140S1FQ-7 is a 40V, 1A Super Barrier Rectifier (SBR) from Diodes Incorporated, packaged in a surface-mount SOD-123F package. It features a low forward voltage of 510 mV typical (0.51V maximum at 1A, +25°C) to minimize conduction losses. The device exhibits low reverse leakage current of 0.1 mA maximum at +25°C, enhancing reliability in high-temperature operation. Its Super Barrier technology (SBR®) provides improved efficiency and thermal stability compared to conventional Schottky rectifiers.

 

The part is qualified to AEC-Q101 automotive standards, is PPAP capable, and manufactured in IATF 16949 certified facilities. The SOD-123F package supports surface-mount assembly with a standard 3000-piece tape-and-reel carrier. The diode is RoHS3 compliant (lead-free finish with matte tin over copper leadframe), halogen and antimony free, and MSL Level 1 per J-STD-020.

 

Applications include boost diodes, blocking diodes, and general rectification in automotive and industrial power systems.
