MSKSEMI · Digital Transistors · SOT-523
DTA114YE-MS from MSKSEMI, 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 | IN | input | Base input of the inverter with built-in bias resistors, rated VIN from -40 V to +6 V, with input resistance R1 of 7 to 13 kΩ (10 kΩ typical). |
| 2 | GND | power_in | Ground pin as labelled on the package; the datasheet gives no further electrical limits for this pin. |
| 3 | OUT | output | Output of the inverter, rated for an output current IO of -70 mA and a peak collector current ICM of -100 mA (absolute maximum). |
