DTA115GUA / DTA115GKA Digital Transistors (built-in resistor) is a digital transistor with built-in resistor that allows positive biasing of the input, eliminates parasitic effects, and makes device design easier and achieves higher mounting densities.
The DTA115GUA (and DTA115GKA) are digital transistors that incorporate thin‑film bias resistors, allowing positive biasing with minimal parasitic effects. The device is designed for simple on/off operation and supports high mounting densities.
The datasheet lists absolute maximum ratings, detailed electrical parameters such as breakdown voltages, current limits, and transition frequency, as well as package dimensions, marking codes, and ordering information. Application notes and export control warnings are also included.
