BSS123-JSM

JSMSEMI · MOSFETs · SOT-23

BSS123-JSM from JSMSEMI, 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 G input Gate; gate-to-source voltage is rated at ±20 V (VGSS) with a typical threshold of 1.9 V (1 V min, 2.8 V max at ID = 250 µA).
2 S passive Source; the MOSFET source terminal, with the body diode running from source to drain (VSD typ 0.85 V, max 1.3 V at IS = 0.3 A).
3 D passive Drain; drain-to-source voltage is rated at 100 V (VDSS) with continuous drain current of 170 mA and pulsed drain current of 680 mA.

CAD (KiCad official)

  • Symbol: BSS123-JSM
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bss123-jsm-etched.step / bss123-jsm-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bss123-jsm.step / bss123-jsm.glb are the bare package body.
