TPRT9742CGJ5

TECH PUBLIC · Power Distribution Switches · SOT-23-5

TPRT9742CGJ5 from TECH PUBLIC, in a SOT-23-5. 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 VOUT power_out Output voltage pin that follows the input voltage; when ENB is high or EN is low, the output is discharged by an internal resistor.
2 GND power_in Ground.
3 OCB output Open-drain fault indication pin that goes low when a current limit or over-temperature condition is detected after a 12ms deglitch time.
4 EN input Enable input: high enables the device, low disables it, and the pin cannot be left floating (high threshold min 1.3V, low threshold max 0.7V).
5 VIN power_in Power supply input connected to the external DC supply, 2.5V to 5.5V operating range (6.5V absolute maximum).

CAD (KiCad official)

  • Symbol: TPRT9742CGJ5
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: tprt9742cgj5-etched.step / tprt9742cgj5-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tprt9742cgj5.step / tprt9742cgj5.glb are the bare package body.

Provenance

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

  • Datasheet: TECH PUBLIC datasheet (8 pp, sha256 b4125d52391fb985, retrieved 2026-10-09, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-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).
