LBSS139WT1G from LRC, in a SC-70. 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, with VGS limited to ±20 V continuous and a threshold VGS(th) of 0.5 V to 1.5 V. |
| 2 | Source | passive | Source of the N-channel MOSFET; continuous drain current is 200 mA at TA = 25°C and pulsed is 800 mA. |
| 3 | Drain | passive | Drain of the N-channel MOSFET, with a maximum drain-source voltage VDSS of 60 V. |
