ULN2803AG Darlington Transistor Array IC SOP-18
type: Product
description: The ULN2803AG is an 8-channel Darlington transistor array IC designed for driving relays, LEDs, solenoids, stepper motors, and other high-current loads from TTL and CMOS logic circuits. Housed in a compact SOP-18 surface-mount package, it integrates eight NPN Darlington pairs with common-emitter outputs and built-in flyback diodes for inductive load protection. The ULN2803AG is widely used in microcontroller-based systems, industrial automation, embedded electronics, and control applications. Features Eight NPN Darlington transistor driver channels. High-voltage outputs up to 50V. 500mA continuous collector current per channel. Integrated suppression diodes for inductive loads. TTL and 5V CMOS logic compatible inputs. High current gain for efficient load driving. Low standby power consumption. SOP-18 surface-mount package. Suitable for automated SMT assembly. RoHS compliant. Applications Relay driver circuits. Stepper motor and DC motor drivers. LED matrix and display drivers. Solenoid and valve control. Microcontroller output expansion. Industrial automation systems. PLC and embedded control circuits. Printer and office automation equipment. Home automation devices. General-purpose high-current switching.
