SL3904

Slkor SLKORMICRO Elec · Bipolar (BJT) · SOT-23

SL3904 from Slkor SLKORMICRO Elec, 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 BASE input Base of the NPN transistor; emitter-base voltage limited to 6 V (VEBO) and VBE(sat) max 1 V at IC=50mA, IB=5mA.
2 EMITTER passive Emitter of the NPN transistor; reference terminal for VCE, with VCEO of 40 V and VEBO of 6 V.
3 COLLECTOR passive Collector of the NPN transistor; VCBO 60 V, VCEO 40 V, continuous collector current 0.2 A.

CAD (KiCad official)

  • Symbol: SL3904
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: sl3904-etched.step / sl3904-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sl3904.step / sl3904.glb are the bare package body.
