DTA143ZMT2L

ROHM Semicon · Bipolar Transistors - BJT · SOT-723

DTA143ZMT2L from ROHM Semicon, 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 (BASE) input Input pin connected to the base through built-in resistor R1 = 4.7kΩ, with an input voltage range of -30 to 5 V and input-off threshold VI(off) max -0.5 V.
2 GND (+) (EMITTER) power_in Ground/emitter pin of the PNP digital transistor, connected to the base through R2 = 47kΩ and tied to the positive supply side (VCC max -50 V).
3 OUT (COLLECTOR) output Output pin at the collector, rated for output current IO of -100 mA maximum and supply voltage VCC of -50 V.

CAD (KiCad official)

  • Symbol: DTA143ZMT2L
  • 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: dta143zmt2l-etched.step / dta143zmt2l-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dta143zmt2l.step / dta143zmt2l.glb are the bare package body.
