BZT52C75-E3-08 from VISHAY(威世), 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 | CATHODE | passive | Cathode, identified by the cathode bar on the SOD-123 outline; the Zener voltage of BZT52C75 is 71.25 V to 78.75 V (nominal 75 V) and reverse voltage VR is 56 V. |
| 2 | A | passive | Anode, the terminal opposite the cathode bar; total power dissipation is 500 mW at RthJL = 250 K/W and 300 mW on FR-4 with the recommended soldering footprint. |
