BZX79C12

onsemi · Zener Diodes · DO-35

BZX79C12 from onsemi, 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, marked by the color band on the DO-35 glass case; the BZX79C12 zener voltage is 11.4 V min to 12.7 V max at 5 mA.
2 A passive Anode, the lead opposite the color band on the DO-35 glass case; forward voltage is 1.5 V max at IF = 100 mA.
