Professional 8-Channel Darlington Transistor Array IC

The ULN2803APG is a high-voltage, high-current Darlington transistor array perfect for interfacing low-power logic circuits with high-power loads. This 18-DIP package contains eight NPN Darlington pairs, each capable of handling 50V and 500mA, with built-in suppression diodes for inductive loads.

Essential for driving stepper motors, relay arrays, LED displays, and other high-current devices from microcontroller outputs. The integrated protection diodes and high current capability make this IC ideal for robotics, automation systems, and industrial control applications requiring reliable high-power switching.
