BSS138AKAR

Nexperia · MOSFETs · SOT-23

BSS138AKAR from Nexperia, 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 terminal of the N-channel MOSFET; gate-source voltage is limited to -20 V to 20 V (Tj = 25 °C) per Table 5.
2 S passive Source terminal of the MOSFET; source current IS is limited to 200 mA at Tamb = 25 °C per Table 5.
3 D passive Drain terminal of the MOSFET; drain-source voltage is limited to 60 V and continuous drain current to 200 mA at VGS = 10 V, Tamb = 25 °C per Table 5.

CAD (KiCad official)

  • Symbol: BSS138AKAR
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bss138akar-etched.step / bss138akar-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bss138akar.step / bss138akar.glb are the bare package body.

Provenance

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

  • Datasheet: Nexperia datasheet (15 pp, sha256 39d145f3b39a916f, retrieved 2026-10-09, 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.
