S3DB

onsemi · Diodes - General Purpose · DO-214AA(SMB)

S3DB from onsemi, in a DO-214AA(SMB). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Cathode passive Cathode of the S3DB rectifier (polarity-mark end), rated 200 V repetitive peak reverse voltage and 3 A average forward current.
2 Anode passive Anode of the S3DB rectifier, with a maximum forward voltage of 1.15 V at IF = 3 A.
