2SK508G-K51-AE3-R from UTC Unisonic Tech, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | S | passive | Source terminal of the N-channel JFET. |
| 2 | D | passive | Drain terminal of the N-channel JFET. Absolute maximum VDSX = 15 V (VGS = -4.0 V); max ID (DC) = 50 mA. |
| 3 | G | input | Gate terminal of the N-channel JFET. VGSO absolute max = -15 V; gate cut-off voltage VGS(off) typically -1.4 V. |
