MST1173TQ

MST · LED Drivers · TO-252

MST1173TQ from MST, in a TO-252. 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 VIN power_in External power input; the datasheet gives a DC input voltage range of 9 V to 24 V for a 25 W lamp load and an absolute maximum of 24 V.
2 VOUT output Flasher output that drives the lamp in series between VOUT and GND, switched by the internal power MOSFET with a peak current limit of 10 A.
3 CEXT passive Connects an external capacitor that is charged from VIN to set the flash timing, with a stated CEXT-to-VOUT peak voltage of 5.3 V.

  • Symbol: MST1173TQ
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252 (KiCad packages3D, STEP)
  • 3D model files: mst1173tq-etched.step / mst1173tq-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mst1173tq.step / mst1173tq.glb are the bare package body.

Provenance

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

  • Datasheet: MST datasheet (8 pp, sha256 41f64521ebea6cad, retrieved 2026-10-27, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • 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).
