SS32B

hongjiacheng · Schottky Diodes · SMB

SS32B from hongjiacheng, in a 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 K passive Cathode, the end marked by the cathode line on the SMB body; SS32B blocks up to VRRM 20 V and VDC 20 V.
2 A passive Anode; SS32B conducts up to 3.0 A average forward current (IF(AV)) with 80 A non-repetitive peak surge (IFSM, 8.3 ms) and VF 0.55 V at 3.0 A.
