LBSS138LT1G

LRC · MOSFETs · SOT-23

LBSS138LT1G 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; gate-to-source voltage is ±20 Vdc continuous max, with threshold VGS(th) of 0.5 V to 1.5 V at ID = 1.0 mAdc.
2 S passive Source of the N-channel MOSFET, connected to the body diode anode in the schematic symbol.
3 D passive Drain; drain-to-source voltage is 50 Vdc max, continuous drain current 200 mA and pulsed 800 mA (tp ≤ 10 µs).
