DTA143ZE

Slkor SLKORMICRO Elec · Digital Transistors · SOT-523

DTA143ZE from Slkor SLKORMICRO Elec, in a SOT-523. 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 through built-in base resistor R1 (4.7 kΩ typ); input voltage range -30 V to +5 V, VI(off) max -0.5 V at VCC=-5 V, IO=-100 µA, VI(on) min -1.3 V.
2 GND power_in Ground (+) terminal, connected to the emitter of the PNP transistor and to R2; supply voltage VCC rated -50 V.
3 OUT output Output (collector) of the PNP digital transistor; output current rated -100 mA, VO(on) max -0.3 V at IO/II=-5 mA/-0.25 mA.

CAD (KiCad official)

  • Symbol: DTA143ZE
  • Footprint: Package_TO_SOT_SMD:SOT-523
  • 3D model: SOT-523, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.8 mm nominal SOT-523 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: dta143ze-etched.step / dta143ze-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dta143ze.step / dta143ze.glb are the bare package body.
