FMMT734

Diodes Incorporated · Darlington Transistors · SOT-23

FMMT734 from Diodes Incorporated, 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 B passive Base of the PNP Darlington transistor; the datasheet states VEBO of -12V maximum and IC of -800mA continuous.
2 E passive Emitter of the PNP Darlington transistor; the datasheet states VCEO of -100V maximum and ICM peak pulse current of -5A.
3 C passive Collector of the PNP Darlington transistor, the single pin on the top side of the package; the datasheet states VCBO of -100V and VCEO of -100V maximum.

CAD (KiCad official)

  • Symbol: FMMT734
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: fmmt734-etched.step / fmmt734-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); fmmt734.step / fmmt734.glb are the bare package body.

Provenance

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

  • Datasheet: Diodes Incorporated datasheet (7 pp, sha256 6c5b3e00bec125b5, retrieved 2026-10-28, tier: manufacturer)
  • 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.
