Additional Details

Each transistor in the DTDG14GPFRAT100 features built-in resistors, with an input resistor of 10kΩ and a series resistor of 47kΩ. This configuration makes the device easy to implement in digital circuits. The collector-emitter voltage (VCEO) is rated at 50V, and the collector current (IC) is rated at 100mA per transistor. The device is commonly available in a small surface mount package, such as SOT-363 or similar. The use of a dual transistor package further reduces the PCB footprint, making it an excellent choice for compact designs.

The DTDG14GPFRAT100 is well-suited for various applications, particularly in portable devices, consumer electronics, and industrial control systems. The integration of the bias resistors simplifies the design and reduces component count, leading to lower overall system cost and improved reliability.
