LNTK3043NT5G from LRC, in a SOT-723. 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 | Gate | input | Gate of the N-channel MOSFET; the datasheet gives a maximum gate-to-source voltage of ±10 V. |
| 2 | Source | passive | Source of the N-channel MOSFET; the datasheet gives a source (body diode) current IS of 286 mA and a pulsed drain current IDM of 400 mA (tp = 10 µs). |
| 3 | Drain | passive | Drain of the N-channel MOSFET; the datasheet gives a drain-to-source voltage VDSS of 20 V. |
