FDN357N

onsemi · MOSFETs · SOT-23

FDN357N from onsemi, 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; logic-level control input, VGSS rated ±20 V continuous with RDS(ON) of 0.090 Ω at VGS = 4.5 V and 0.060 Ω at VGS = 10 V.
2 S passive Source terminal of the N-channel MOSFET, with a maximum continuous body-diode forward current of 0.42 A.
3 D passive Drain terminal, rated for VDSS of 30 V and 1.9 A continuous (10 A pulsed) drain current.

CAD (KiCad official)

  • Symbol: FDN357N
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: fdn357n-etched.step / fdn357n-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); fdn357n.step / fdn357n.glb are the bare package body.

Provenance

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

  • Datasheet: onsemi datasheet (5 pp, sha256 53c45d4c99a0335f, retrieved 2026-10-09, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+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).
