DTC143ECA-MS

MSKSEMI · Digital Transistors · SOT-23

DTC143ECA-MS from MSKSEMI, 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 IN input Input terminal of the built-in bias-resistor digital transistor; the input voltage VIN is rated from -10 V to +30 V.
2 GND power_in Ground reference terminal for the device.
3 OUT output Output terminal of the NPN digital transistor; output current IO is rated at 100 mA maximum.

CAD (KiCad official)

  • Symbol: DTC143ECA-MS
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: dtc143eca-ms-etched.step / dtc143eca-ms-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dtc143eca-ms.step / dtc143eca-ms.glb are the bare package body.

Provenance

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

  • Datasheet: MSKSEMI datasheet (9 pp, sha256 a182ed49128cc14d, retrieved 2026-11-12, 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.
