Description

A Darlington transistor array is a specialized integrated circuit (IC) that consists of multiple Darlington transistor pairs on a single chip.

The KID65003AP is high-voltage, high-current darlington transistor array comprised of seven NPN darlington pairs. All units feature internal clamp diodes for switching inductive loads.

A Darlington transistor array is a specialized integrated circuit (IC) that consists of multiple Darlington transistor pairs on a single chip. It combines the advantages of Darlington transistor configuration, which offers high current gain, with the convenience of integrated circuit technology.

1. Darlington Transistor Configuration: The Darlington transistor array incorporates multiple Darlington transistor pairs. A Darlington pair is a combination of two bipolar junction transistors (BJTs) connected together to provide a high current gain.

2. High Current Gain: The Darlington configuration provides a very high current gain compared to a single transistor. The current gain is the ratio of output current to input current, and the Darlington configuration allows for significant amplification of input current.

3. Integrated Circuit Package: The Darlington transistor array is packaged as an integrated circuit, typically in a standard IC package such as a DIP (Dual In-line Package) or surface-mount technology (SMT) package. This allows for easy integration and soldering onto a printed circuit board (PCB).

4. Multiple Transistor Pairs: The array includes multiple Darlington transistor pairs, often with a common emitter or common collector configuration. This allows for multiple inputs and outputs, providing flexibility in designing various electronic circuits.
