The ULN 2803 is a high-performance 50V, 500mA Darlington transistor array designed for driving a wide range of inductive loads. It consists of eight NPN Darlington pairs that come with common-cathode clamp diodes, which protect against back-emf and allow for efficient switching of inductive loads such as motors, relays, and solenoids. Each Darlington pair is rated for 500mA of collector current, and they can be connected in parallel to increase the current capability when needed.With its 2.7kΩ series base resistors, the ULN2803C ensures compatibility with TTL and 5V CMOS logic levels, making it ideal for integration into microcontroller or digital control systems. This device is an excellent choice for applications requiring reliable, high-voltage, and high-current switching in automation, appliance, and industrial control systems.
