The HT2803ANZ is a Darlington transistor array manufactured by HTCSEMI. It is packaged in a dual in-line package (DIP) with 18 pins. It is RoHS-compliant, meaning it contains no hazardous components such as lead, mercury, and certain flame retardants. The HT2803ANZ is a seven NPN transistor array with internal base resistors for good matching performance and higher gain for power and low level switching applications. It features low crossover current, high DC current gain, and low saturation voltage. The collector current is a maximum of 200 mA and its power dissipation is 500 mW. It is ideal for use in logic level translation, LED drivers, and industrial and automotive applications.
