**Yangzhou Yangjie Elec Tech** · Digital Transistors · SOT-363

UMH11N from Yangzhou Yangjie Elec Tech, 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 | GND (Emitter) | power_in | Emitter of the first NPN transistor, connected to ground and to the R2 resistor. |
| 2 | Input (base) | input | Base input of the first transistor through built-in R1 (7 to 13 kΩ, 10 kΩ typ); input voltage range -10 to +40 V. |
| 3 | Output (collector) | output | Collector output of the second transistor; output current up to 100 mA and supply voltage up to 50 V. |
| 4 | GND (Emitter) | power_in | Emitter of the second NPN transistor, connected to ground and to the R2 resistor. |
| 5 | Input (base) | input | Base input of the second transistor through built-in R1 (7 to 13 kΩ, 10 kΩ typ); input voltage range -10 to +40 V. |
| 6 | Output (collector) | output | Collector output of the first transistor; output current up to 100 mA and supply voltage up to 50 V. |

## CAD (KiCad official)

- Symbol: `UMH11N`
- Footprint: `Package_TO_SOT_SMD:SOT-363_SC-70-6`
- 3D model: SOT-363 (KiCad packages3D, STEP)
- 3D model files: `umh11n-etched.step` / `umh11n-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `umh11n.step` / `umh11n.glb` are the bare package body.
