# DTA114YCA

**TECH PUBLIC** · Digital Transistors · SOT-23

DTA114YCA from TECH PUBLIC, 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 | IN (B) | input | Input/base pin through built-in 10kΩ series resistor R1 (R2 47kΩ to emitter); input voltage range +6 to -40 V. |
| 2 | GND (E) | power_in | Ground/emitter pin of the PNP digital transistor, common to R2 and the emitter. |
| 3 | OUT (C) | output | Output/collector pin; output current max -70 mA, collector current max -100 mA, supply voltage max -50 V. |

## CAD (KiCad official)

- Symbol: `DTA114YCA`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `dta114yca-etched.step` / `dta114yca-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `dta114yca.step` / `dta114yca.glb` are the bare package body.
