# BZG03C150G

**onsemi** · Zener Diodes · SMA(DO-214AC)

BZG03C150G from onsemi, in a SMA(DO-214AC). 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, marked by the polarity band on the package (Style 1), and the device is a unidirectional Zener, so it must be connected with the cathode at the higher potential for regulation. |
| 2 | ANODE | passive | Anode terminal, opposite the polarity band, forming the Zener junction with the cathode. |
