LN4501LT1G from LRC, 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 terminal; gate-to-source voltage is rated ±12 V (VGS), with VGS(TH) of 0.6 V to 1.2 V at VDS = VGS and ID = 250 µA. |
| 2 | S | passive | Source terminal; continuous source current (body diode) is rated 1.6 A and the forward diode voltage VSD is 0.8 V to 1.2 V at VGS = 0 V, ISD = 1.6 A. |
| 3 | D | passive | Drain terminal; drain-to-source voltage is rated 20 V and continuous drain current is rated 3.2 A at steady state (TA = 25 °C). |
