MMUN2235

WPMtek(Wei Pan Microelectronics) · Digital Transistors · SOT-23

MMUN2235 from WPMtek(Wei Pan Microelectronics), 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 (input) of the NPN bias-resistor transistor, connected through R1 (2.2 kΩ for MMUN2235) with R2 (47 kΩ) to the emitter.
2 Emitter passive Emitter (common) of the NPN bias-resistor transistor, the ground-side reference for the circuit.
3 Collector passive Collector (output) of the NPN bias-resistor transistor, rated VCEO 50 V and IC 100 mA maximum.

  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: mmun2235-etched.step / mmun2235-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmun2235.step / mmun2235.glb are the bare package body.
