Diodes Inc. Transistors - Bipolar (BJT) - Arrays, Pre-Biased DDC144EH-7 are a type of transistor array designed for use in a variety of applications. These transistors are pre-biased, meaning that they are already set up for use in a circuit, and feature a maximum power rating of 150mW and a frequency of 47kHz. This makes them ideal for use in low-power, high-frequency applications such as radio frequency (RF) amplifiers, oscillators, and signal processing circuits. They are also suitable for use in audio amplifiers, power supplies, and other applications that require a low-power, high-frequency transistor array. The DDC144EH-7 transistors are designed to provide reliable performance and are available in a variety of packages, making them suitable for a wide range of applications.
