TIP42C

JSMSEMI · Bipolar (BJT) · TO-220

TIP42C from JSMSEMI, in a TO-220. 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 terminal of the PNP transistor; continuous base current is limited to -2.0 A and emitter-to-base voltage to -5.0 V.
2 Collector passive Collector terminal of the PNP transistor; for TIP42C, VCEO is -100 V, continuous collector current is limited to -6.0 A (peak -10 A), and collector power dissipation is 65 W at Tc=25°C.
3 Emitter passive Emitter terminal of the PNP transistor; emitter-to-base voltage is limited to -5.0 V.

CAD (KiCad official)

  • Symbol: TIP42C
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220 (KiCad packages3D, STEP)
  • 3D model files: tip42c-etched.step / tip42c-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tip42c.step / tip42c.glb are the bare package body.
