BSS138P-VB

VBsemi Elec · MOSFETs · SOT-23(TO-236)

BSS138P-VB from VBsemi Elec, in a SOT-23(TO-236). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model). Symbol and footprint from KiCad-official CAD; the 3D model is generated from the datasheet's package dimensions.

Pinout

Pin Name Type Function
1 G input Gate terminal; gate-source voltage is rated at ±20 V (VGS).
2 S passive Source terminal, the reference for the gate-source voltage and the drain current, with the body diode forward voltage specified at IS = 100 mA, VGS = 0 V.
3 D passive Drain terminal, rated for 60 V drain-source voltage (VDS) with 250 mA continuous drain current at TA = 25 °C.

CAD (land: KiCad; 3D: generated from the datasheet)

  • Symbol: BSS138P-VB
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23(TO-236), generated on the KiCad land (body 1.3 x 2.92 mm, terminals on the pads, 1.0050000000000001 mm tall, datasheet A, midpoint of min and max). KiCad's stock model for this land is taller than the datasheet allows, so the model is generated from the datasheet drawing; the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
  • 3D model files: bss138p-vb-etched.step / bss138p-vb-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bss138p-vb.step / bss138p-vb.glb are the bare package body.

Provenance

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

  • Datasheet: VBsemi Elec datasheet (8 pp, sha256 0cb3d74faec00c80, retrieved 2026-11-13, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-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: land: KiCad official libraries (CC-BY-SA 4.0); 3D: generated from the datasheet's package dimensions (provenance.model_3d_generated).
