ULN2803 SOIC-18 Wide – 8-Channel Darlington Transistor Array Driver IC

The ULN2803 is an 8-channel Darlington transistor array driver IC designed to interface logic-level signals with higher current/voltage loads. Each channel can handle up to 500mA at 50V, making it ideal for driving relays, stepper motors, lamps, solenoids, and LED displays. Packaged in a SOIC-18 wide surface-mount package, the ULN2803 is widely used in automation, robotics, industrial control, and embedded systems where multiple loads need to be controlled by microcontrollers or logic circuits. Its built-in suppression diodes make it especially suited for inductive load driving. Features: 8-channel Darlington transistor array driver IC High current handling: up to 500mA per channel High voltage tolerance: up to 50V output Built-in clamp diodes for driving inductive loads TTL/CMOS compatible inputs Compact SOIC-18 wide SMD package Commonly used for relay, motor, solenoid, and LED driving Reliable performance in automation and control applications Specifications: Model: ULN2803 Package Type: SOIC-18 Wide (Surface Mount) Number of Channels: 8 Output Current (per channel): 500mA max Output Voltage: Up to 50V Input Compatibility: TTL and CMOS logic Integrated Protection: Clamp diodes for inductive loads Applications: Relay driver, LED driver, stepper motor driver, solenoid driver, automation, robotics, embedded systems Package Includes: 1 x ULN2803 SOIC-18 Wide Darlington Driver IC
