LBSS139LT1G-TP

TECH PUBLIC · MOSFETs · SOT-23

LBSS139LT1G-TP from TECH PUBLIC, 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-source voltage limited to ±20 V absolute maximum, with ESD protection, threshold 0.8 V min to 1.5 V max at 250 µA.
2 S passive Source of the N-channel MOSFET; continuous drain current is 360 mA at TA = 25°C.
3 D passive Drain of the N-channel MOSFET; drain-source voltage is 50 V maximum and pulsed drain current is 1500 mA.
