FMMT618-JSM

JSMSEMI · Bipolar (BJT) · SOT-23

FMMT618-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 BASE input Base of the NPN transistor; IB max 0.5 A, VEBO max 5 V, base-emitter on voltage max 1 V at IC=2.5 A, VCE=2 V.
2 EMITTER passive Emitter of the NPN transistor; emitter-base voltage rating 5 V.
3 COLLECTOR passive Collector of the NPN transistor; VCEO/VCBO 20 V, continuous IC 2.5 A, total dissipation 350 mW.

CAD (KiCad official)

  • Symbol: FMMT618-JSM
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: fmmt618-jsm-etched.step / fmmt618-jsm-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); fmmt618-jsm.step / fmmt618-jsm.glb are the bare package body.
