BZV49-C24 from Nexperia, in a SOT-89-3. 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 | anode | passive | Anode of the BZV49-C24 voltage regulator diode, pinned as lead 1 in the SOT89 outline; the series total power dissipation is limited to max. 1 W. |
| 2 | cathode | passive | Cathode of the BZV49-C24 voltage regulator diode, pinned as lead 2 (middle lead) in the SOT89 outline. |
| 3 | anode | passive | Anode of the BZV49-C24 voltage regulator diode, pinned as lead 3 in the SOT89 outline; the series non-repetitive peak reverse power dissipation is limited to max. 40 W. |
