The ULN2003AN is a widely used high voltage, high current Darlington transistor array. It consists of seven NPN Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads. The ULN2003AN is a highly efficient and reliable solution for driving a wide range of loads such as relays, solenoids, stepper motors, and other high-current or high-voltage devices. This device is designed to interface directly with low-level logic signals and can be used as a relay driver IC. With its built-in diodes for back EMF protection, it provides a convenient and cost-effective solution for driving various inductive loads in many different applications. The ULN2003AN is suitable for a wide range of industrial, consumer, and automotive applications. It comes in a 16-pin DIP or SOIC package, making it easy to use in both through-hole and surface-mount applications. This product is manufactured in China by reputable and quality-focused factories, ensuring reliability and consistent performance.
