# ZMM15V

**HXY MOSFET** · Zener Diodes · LL-34

ZMM15V from HXY MOSFET, 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 banded end of the LL-34 (MiniMELF) body; for ZMM15V the Zener voltage is 13.8...15.6 V at IZT = 5 mA and it is the terminal taken positive in reverse (Zener) operation. |
| 2 | A | passive | Anode, the unbanded end of the LL-34 (MiniMELF) body; forward voltage is 1 V max at IF = 100 mA and power dissipation is 500 mW max. |
