BZV49-C4V3 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 terminal of the BZV49 voltage regulator diode; the device is rated for 250 mA continuous forward current and 1 W total power dissipation at Tamb = 25 °C (mounted on a ceramic substrate, 2.5 cm², 0.7 mm). |
| 2 | cathode | passive | Cathode terminal of the regulator diode; the SOT89 package includes a collector pad for good heat transfer. |
| 3 | anode | passive | Second anode terminal of the regulator diode, electrically the same anode as pin 1; the device is rated for 250 mA continuous forward current and 1 W total power dissipation at Tamb = 25 °C. |
