LBSS138WT1G

LRC · MOSFETs · SC-70

LBSS138WT1G 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 terminal; gate-to-source voltage is rated ±20 V continuous with a threshold VGS(th) of 0.5 V to 1.5 V at VDS = VGS, ID = 1.0 mA.
2 Source passive Source terminal of the N-channel MOSFET; drain current is rated 200 mA continuous and 800 mA pulsed (tp ≤ 10 µs).
3 Drain passive Drain terminal of the N-channel MOSFET; drain-source voltage is rated 50 V maximum.
