Bencent · Zener Diodes · SOD-123
BW-D1G18VT1G-5 from Bencent, 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 | K | passive | Cathode, the banded end of the package (pin 1 in the top view); the zener reverse-voltage terminal, 18 V nominal (17.10 V to 18.90 V) at IZT = 7.0 mA. |
| 2 | A | passive | Anode, the end opposite the cathode band (pin 2 in the top view and schematic). |
