BZT52B30 from CBI, in a SOD-123. 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 as pin 1 in the datasheet pin description; the datasheet rates the device at 350 mW power dissipation on a ceramic PCB. |
| 2 | Anode | passive | Anode terminal of the zener diode, identified as pin 2 in the datasheet pin description; the forward voltage is listed as 0.9 V at IF = 10 mA. |
