2SK545-11D-TB-E from onsemi, in a TO-236-3(SOT-23-3). 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 | Source | passive | Source terminal of the N-channel JFET; the datasheet assigns no pin-specific limit, so the absolute maximum ratings (for example VDSS 40 V) apply. |
| 2 | Drain | passive | Drain terminal of the N-channel JFET, with drain-to-source voltage VDSS rated at 40 V in the absolute maximum ratings. |
| 3 | Gate | input | Gate terminal of the N-channel JFET, with gate current IG rated at 10 mA, gate-to-drain voltage VGDS at −40 V, and gate cutoff current IGSS at −500 pA maximum (VGS = −20 V, VDS = 0 V). |
