DTC123JM

Changjing · Digital Transistors · SOT-723

DTC123JM from Changjing, in a SOT-723. 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 Base input of the built-in bias-resistor inverter; the datasheet limits the input voltage VIN to -5 V to +12 V (absolute maximum ratings).
2 GND power_in Ground reference pin for the device; the datasheet gives no separate voltage or current limit for this pin.
3 OUT output Collector output of the transistor; the datasheet limits output current IO to 100 mA maximum and gives a typical on-state output voltage VO(on) of 0.1 V to 0.3 V at IO/II = 5 mA/0.25 mA.

Key specifications

Parameter Value
Manufacturer Changjing
Package SOT-723
Category Transistors/Thyristors
Pins 3

CAD (KiCad official)

  • Symbol: DTC123JM
  • Footprint: Package_TO_SOT_SMD:SOT-723
  • 3D model: SOT-723, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.5 mm nominal SOT-723 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: dtc123jm-etched.step / dtc123jm-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dtc123jm.step / dtc123jm.glb are the bare package body.

Provenance

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

  • Datasheet: Changjing datasheet (15 pp, sha256 87b8e288c3b9084b, retrieved 2026-10-09, 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.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
