UMH2N

Changjing · Digital Transistors · SOT-363

UMH2N from Changjing, in a SOT-363. 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 E1 passive Emitter (ground) of transistor 1 (NPN digital transistor, DTC144E chip).
2 B1 input Input (base through built-in R1, with R2 to emitter) of transistor 1; input voltage rated -10 to +40 V.
3 C2 passive Collector (output) of transistor 2; output current max 100 mA, supply voltage max 50 V.
4 E2 passive Emitter (ground) of transistor 2 (NPN digital transistor, DTC144E chip).
5 B2 input Input (base through built-in R1, with R2 to emitter) of transistor 2; input voltage rated -10 to +40 V.
6 C1 passive Collector (output) of transistor 1; output current max 100 mA, supply voltage max 50 V.

CAD (KiCad official)

  • Symbol: UMH2N
  • Footprint: Package_TO_SOT_SMD:SOT-363_SC-70-6
  • 3D model: SOT-363 (KiCad packages3D, STEP)
  • 3D model files: umh2n-etched.step / umh2n-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); umh2n.step / umh2n.glb are the bare package body.
