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.

CAD (KiCad official)

  • Symbol: LBSS139LT1G-TP
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: lbss139lt1g-tp-etched.step / lbss139lt1g-tp-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lbss139lt1g-tp.step / lbss139lt1g-tp.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: TECH PUBLIC datasheet (5 pp, sha256 a25b264f68af4f45, retrieved 2026-10-18, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
