2SK1590-T1B-A-VB from VBsemi Elec, in a SOT-23. 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, with a typical threshold of 2 V (VGS(th) at VDS = VGS, ID = 250 µA). |
| 2 | S | passive | Source of the N-channel MOSFET; continuous drain current is 250 mA at TA = 25 °C (TJ = 150 °C). |
| 3 | D | passive | Drain; drain-source voltage rated at 60 V, with pulsed drain current up to 800 mA. |
