TECH PUBLIC · MOSFETs · SOT-323
LBSS139WT1G-TP from TECH PUBLIC, in a SOT-323. 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, rated for VGS of ±20 V maximum with a gate threshold of 0.8 V min to 1.5 V max at ID = 250 µA. |
| 2 | SOURCE | passive | Source of the N-channel MOSFET, with continuous drain current of 360 mA and pulsed drain current of 1500 mA. |
| 3 | DRAIN | passive | Drain of the N-channel MOSFET, rated for 50 V drain-source voltage (VDSS). |
