LWT1H7AM from Lewa Micro, 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-to-source voltage is limited to ±20 V, with a threshold VGS(TH) of 1.8 V typ. |
| 2 | S | passive | Source of the N-channel MOSFET; continuous drain current is 4.5 A at TA=25 °C. |
| 3 | D | passive | Drain; drain-to-source voltage is rated to 100 V and pulsed drain current to 18 A. |
