STLD128DNT4

STMicroelectronics · Bipolar (BJT) · DPAK

STLD128DNT4 from STMicroelectronics, in a DPAK. 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 B input Base of the NPN transistor; base current is rated 2 A continuous and 4 A peak (tP < 5 ms).
2 C passive Collector, connected to the TAB; VCES is 700 V, VCEO is 400 V and collector current is 4 A (8 A peak).
3 E passive Emitter, with the integrated antiparallel collector-emitter diode connected between emitter and collector.

CAD (KiCad official)

  • Symbol: STLD128DNT4
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: DPAK (KiCad packages3D, STEP)
  • 3D model files: stld128dnt4-etched.step / stld128dnt4-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); stld128dnt4.step / stld128dnt4.glb are the bare package body.
