VB1201K from VBsemi Elec, in a SOT-23(TO-236). 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 | G | input | Gate; gate-source voltage limited to ±20 V, threshold 1.5 V to 3.5 V at VDS = VGS, ID = 250 µA. |
| 2 | S | passive | Source; continuous source (diode) current is 0.6 A (5 s) and 0.45 A steady state at TA = 25 °C. |
| 3 | D | passive | Drain; drain-source voltage rated 200 V, continuous drain current 0.6 A (5 s) and 0.45 A steady state at TA = 25 °C. |
