BVSS123LT1G

onsemi · MOSFETs · SOT-23

BVSS123LT1G from onsemi, in a SOT-23. 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 Gate input Gate control terminal; VGS is limited to ±20 Vdc continuous and ±40 Vpk non-repetitive, with VGS(th) of 1.6 to 2.6 Vdc.
2 Source passive Source terminal and reference for the gate and drain ratings; the datasheet gives no separate source-pin limit.
3 Drain passive Drain terminal; VDSS is 100 Vdc, with continuous drain current ID of 0.17 Adc and pulsed IDM of 0.68 Adc, and the package power dissipation may lower the continuous current.

CAD (KiCad official)

  • Symbol: BVSS123LT1G
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bvss123lt1g-etched.step / bvss123lt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bvss123lt1g.step / bvss123lt1g.glb are the bare package body.
