MM5Z15VT1G from onsemi, in a SOD-523. 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 | Cathode | passive | Cathode (polarity band) of the 15 V Zener diode; VZ is 14.3 V min, 15 V nom, 15.8 V max at IZT = 5 mA, and the pin sits positive of the anode in reverse (Zener) operation. |
| 2 | Anode | passive | Anode of the Zener diode; forward voltage is 0.9 V max at IF = 10 mA. |
