BSS84KT7

Siliup · MOSFETs · SOT-723

BSS84KT7 from Siliup, 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 G input Gate; gate-source voltage limited to ±20 V (abs max), threshold -0.8 to -2.5 V at ID=-250µA, with ESD protection to 2 kV.
2 S passive Source; P-channel MOSFET source terminal, with body diode forward voltage up to -1.2 V at IS=-1A.
3 D passive Drain; drain-source voltage rated -60 V and continuous drain current -130 mA.

CAD (KiCad official)

  • Symbol: BSS84KT7
  • 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: bss84kt7-etched.step / bss84kt7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bss84kt7.step / bss84kt7.glb are the bare package body.
