2DA1774R-7-F

Diodes Incorporated · Bipolar Transistors - BJT · SOT-523

2DA1774R-7-F from Diodes Incorporated, 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 B input Base of the PNP transistor; V(BR)EBO is -6V min, and hFE for the R grade is 180 to 390 at VCE = -6V, IC = -1mA.
2 E passive Emitter of the PNP transistor; the emitter-base voltage rating VEBO is -6V.
3 C passive Collector of the PNP transistor; continuous IC is -150mA, VCBO is -60V and VCEO is -50V, and it is the lead referenced for the thermal pad (RthJA 833 °C/W).

CAD (KiCad official)

  • Symbol: 2DA1774R-7-F
  • 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: 2da1774r-7-f-etched.step / 2da1774r-7-f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 2da1774r-7-f.step / 2da1774r-7-f.glb are the bare package body.
