BZT52B27 from BORN, 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, marked by the color band; the 27 V (26.46-27.54 V at IZT=2 mA) Zener voltage appears here, with max reverse current 0.1 uA at VR=18.9 V. |
| 2 | A | passive | Anode of the Zener diode; device power dissipation is 500 mW max and junction temperature is 150 °C max. |
