BZT52C43T from TECH PUBLIC, in a SOD-523. 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 | Cathode of the Zener diode; for BZT52C43T, Vz is 43 V nominal (40.0 to 46.0 V) at the test current, with 150 mW power dissipation. |
| 2 | ANODE | passive | Anode of the Zener diode; forward voltage is 0.9 V at IF=10 mA. |
