# SZNZ9F15VT5G

**onsemi** · Zener Diodes · SOD-923

SZNZ9F15VT5G from onsemi, in a SOD-923. 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 terminal of the Zener diode, identified by the polarity band on the SOD-923 package (Style 1: pin 1 = cathode). |
| 2 | Anode | passive | Anode terminal of the Zener diode, which is the pin opposite the cathode polarity band. |
