SS52

TWGMC · Schottky Barrier Diodes (SBD) · SMA(DO-214AC)

SS52 from TWGMC, in a SMA(DO-214AC). 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 terminal, identified by the color band on the body; the datasheet gives reverse voltage ratings of 20 to 200 V for the SS52 to SS5200 family and forward current of 5.0 A.
2 Anode passive Anode terminal of the Schottky barrier rectifier, which carries forward current toward the cathode.
