ULN2803AFWG 8-Channel Darlington Transistor Array IC – SOIC-18

The ULN2803AFWG IC is a high-current, high-voltage 8-channel Darlington sink driver, designed for driving a wide range of inductive and resistive loads. Each channel integrates an NPN Darlington pair capable of sinking up to 500mA, making the device highly suitable for relays, solenoids, lamps, motors, LED arrays, and other moderate-power loads.

This IC includes integrated clamp diodes for safe switching of inductive loads and supports logic-level input compatibility with most common logic families. With a minimum sustaining voltage of 50V, the ULN2803AFWG provides reliable switching performance in industrial, automotive, and consumer electronics applications. The compact SOIC-18 (SOL-18) package ensures easy integration into space-constrained PCB layouts.
