BZX55C36V

ST(Semtech) · Zener Diodes · DO-35

BZX55C36V from ST(Semtech), in a DO-35. 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 lead, marked by the cathode band on the DO-35 glass case; Zener voltage 34...38 V at IZT = 5 mA for the BZX55C36, with the cathode connected to the positive side in reverse (Zener) operation.
2 A passive Anode lead at the end opposite the cathode band of the DO-35 glass case; forward voltage max. 1 V at IF = 100 mA.
