BZB784-C10 from Nexperia, in a SOT-323-3. 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 | cathode | passive | Cathode of the first voltage regulator diode; the device is rated for a continuous forward current of 200 mA and a total power dissipation of 350 mW with two diodes loaded. |
| 2 | cathode | passive | Cathode of the second voltage regulator diode, giving the double-diode configuration with a shared anode on pin 3. |
| 3 | common anode | passive | Common anode shared by both voltage regulator diodes in the package. |
