BSS138

Changjing · MOSFETs · SOT-23

BSS138 from Changjing, 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 GATE input Gate terminal: continuous gate-source voltage VGSS is limited to ±20 V, and gate threshold VGS(th) is 0.80 V min to 1.50 V max at VDS = VGS, ID = 1 mA.
2 SOURCE passive Source terminal: body diode forward voltage VSD is 1.4 V max at IS = 0.44 A and VGS = 0 V.
3 DRAIN passive Drain terminal: drain-source voltage VDS is rated 50 V, continuous drain current ID is 0.22 A, and RDS(on) is 3.5 Ω max at VGS = 10 V (6 Ω max at VGS = 4.5 V).

CAD (KiCad official)

  • Symbol: BSS138
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bss138-etched.step / bss138-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bss138.step / bss138.glb are the bare package body.

Provenance

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

  • Datasheet: Changjing datasheet (5 pp, sha256 0c1c1f76b4802dda, retrieved 2026-10-08, 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: KiCad official libraries (CC-BY-SA 4.0).
