ST Semtech · Zener Diodes · LL-34
ZMM5250BPF 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 of the glass MiniMELF body carrying the cathode mark band; for ZMM5250BPF the zener voltage is 19 V min to 21 V max at IZT = 6.2 mA (nominal 20 V). |
| 2 | A | passive | Anode, the unmarked end of the glass MiniMELF body opposite the cathode band; the datasheet gives a forward voltage of 1.1 V max at IF = 200 mA. |
