LGE · Zener Diodes · SOD-123
BZT52B11 from LGE, 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 end marked with the band on the SOD-123 drawing; it takes the positive voltage in Zener (reverse) operation, with a nominal VZ of 11 V (10.8 to 11.2 V) at IZT = 5 mA for BZT52B11. |
| 2 | A | passive | Anode, the unbanded end of the SOD-123 package; forward voltage is 0.9 V at IF = 10 mA and power dissipation is 500 mW. |
