ULN2003 7-Channel Darlington Relay Driver SOP16 SMD IC

ULN2003 7-Channel Darlington Relay Driver SOP16 SMD IC

The ULN2003 7-Channel Darlington Relay Driver is a highly versatile and reliable integrated circuit designed for interfacing low-level logic with high-power loads. This SOP16 surface-mount device (SMD) houses seven NPN Darlington pairs, each capable of delivering up to 500mA of output current with a maximum voltage of 50V. For applications requiring more current, multiple channels can be paralleled. Integrated clamp diodes are included to protect against voltage spikes from inductive loads, making the ULN2003 ideal for driving components such as relays, stepper motors, solenoids, and lamps.

Engineered for robust performance and easy integration, the ULN2003 IC is commonly used in automation, control systems, and embedded projects where switching of high-current devices is required. Its Darlington configuration ensures high gain and simplified control through TTL or CMOS logic levels. Thanks to its compact SOP16 SMD packaging, the ULN2003 saves valuable PCB space while offering a reliable solution for interfacing microcontrollers with power-hungry output devices.
