**MCC Micro Commercial Components** · Digital Transistors · SOT-523

DTC114TE-TP from MCC Micro Commercial Components, in a SOT-523. 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 NPN bias-resistor transistor, where the built-in input resistor R1 (10 typ., 7 min., 13 max., in the datasheet's garbled unit read as kΩ) is connected. |
| 2 | Emitter | passive | Emitter terminal of the NPN digital transistor; the datasheet's maximum emitter-base voltage VEBO is 5 V. |
| 3 | Collector | passive | Collector terminal of the NPN digital transistor; the datasheet limits are VCBO 50 V, VCEO 50 V, continuous IC 100 mA, and collector dissipation PC 150 mW. |

## CAD (KiCad official)

- Symbol: `DTC114TE-TP`
- Footprint: `Package_TO_SOT_SMD:SOT-523`
- 3D model: SOT-523, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.8 mm nominal SOT-523 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
- 3D model files: `dtc114te-tp-etched.step` / `dtc114te-tp-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `dtc114te-tp.step` / `dtc114te-tp.glb` are the bare package body.
