SPD9103W

TECH PUBLIC · MOSFETs · SOD-323

SPD9103W from TECH PUBLIC, in a SOD-323. 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 1 passive Pin 1 is one terminal of the bidirectional TVS clamp, tied to the top node of the internal diode network; the datasheet gives a Nominal Reverse Working Voltage (VRWM) of 3.3 V max and a Breakdown Voltage (VBR) of 4 V min at IT = 1 mA.
2 2 passive Pin 2 is the other terminal of the bidirectional TVS clamp, tied to the bottom node of the internal diode network; the datasheet gives a Junction Capacitance of 1 pF typical at VR = 0 V, f = 1 MHz and a Clamping Voltage of 9 V max at IPP = 1 A (8/20 µs).

CAD (KiCad official)

  • Symbol: SPD9103W
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: spd9103w-etched.step / spd9103w-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); spd9103w.step / spd9103w.glb are the bare package body.

Provenance

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

  • Datasheet: TECH PUBLIC datasheet (4 pp, sha256 9c39b7c2f6ea53fb, retrieved 2026-11-04, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-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).
