Foshan Blue Rocket Elec · Zener Diodes · SOD-123
BRBZT52C12Q from Foshan Blue Rocket Elec, 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 | Zener diode cathode terminal in the SOD-123 plastic package; the datasheet states only the pin function (PIN1: Cathode) and gives device ratings of 500 mW power dissipation and -65 to 150 °C junction and storage temperature. |
| 2 | Anode | passive | Zener diode anode terminal in the SOD-123 plastic package; the datasheet states only the pin function (PIN2: Anode) and gives no separate pin-level electrical limits. |
