ULN2803ALN

The ULN2803A Darlington Transistor Array is a highly versatile and widely used driver IC designed to interface low-power logic signals with higher-current loads. Supplied in a standard 18-pin DIP through-hole package, it is ideal for breadboarding, prototyping, repairs, and permanent installations.

Featuring eight high-current Darlington pairs with built-in flyback diodes, the ULN2803A is perfect for driving relays, solenoids, lamps, LED arrays, and stepper motors directly from microcontrollers, logic ICs, or PLC outputs. Its robust design and ease of use make it a staple component in both hobbyist and professional electronics. Fully stocked in the UK for fast dispatch.
