TPZ12VCS3 from TECH PUBLIC, in a SOT-23. 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 | A | passive | Zener anode, drawn in the SOT23 pin diagram as the bottom end of the diode; the TPZ12VCS3 has Vz 11.40 V min, 12.00 V nom and 12.70 V max at IZT = 5 mA. |
| 2 | NC | unconnected | Pin 2 is shown in the SOT23 pin diagram with no internal connection to the zener diode. |
| 3 | K | passive | Zener cathode, drawn in the SOT23 pin diagram as joined to the top (bar) end of the diode; the device dissipates 350 mW maximum. |
