ZMM5246BPF

ST Semtech · Zener Diodes · LL-34

ZMM5246BPF from ST Semtech, in a LL-34. 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 with the cathode band on the LL-34 glass case; it goes positive of the anode in zener (reverse) operation, and ZMM5246BPF has VZnom 16 V (15.2 to 16.8 V) at IZT 7.8 mA.
2 A passive Anode, the unmarked end of the LL-34 glass case; forward voltage is 1.1 V max at IF = 200 mA and total power dissipation is 500 mW.
