BZT52-C18S_R1_10001

PANJIT International · Zener Diodes · SOD-323

BZT52-C18S_R1_10001 from PANJIT International, in a SOD-323. 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, marked by the color band on the SOD-323 body; the zener breakdown voltage (VZ, 17.10 to 18.90 V for the BZT52-C18S) is referenced to this terminal.
2 Anode passive Anode, the terminal opposite the color band cathode; it is the non-band end of the SOD-323 package.
