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.\u003cbr\u003e\u003cbr\u003eEngineered 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.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e\u003cbr\u003eProduct Images are shown for illustrative purposes only and may differ from the actual product.\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eTechnical Details\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eModel Name: ULN2003\u003c\/li\u003e\n\u003cli\u003eCase\/Package: SMD 16 (SOP-16)\u003c\/li\u003e\n\u003cli\u003eNumber of Channels: 7\u003c\/li\u003e\n\u003cli\u003eOutput Voltage: Up to 50V\u003c\/li\u003e\n\u003cli\u003eOutput Current: 0.5A (500mA) per channel\u003c\/li\u003e\n\u003cli\u003eBase Current: 25mA per channel\u003c\/li\u003e\n\u003cli\u003eInput Voltage: TTL\/CMOS compatible\u003c\/li\u003e\n\u003cli\u003eBuilt-in Protection: Freewheeling (flyback) diodes for inductive loads\u003c\/li\u003e\n\u003cli\u003eOperating Temperature: -40°C to +70°C\u003c\/li\u003e\n\u003cli\u003ePackage Type: SOP-16 (Small Outline Package)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eFeatures\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eSeven Darlington Transistors: Provides seven high-current outputs\u003c\/li\u003e\n\u003cli\u003eHigh Voltage Tolerance: Supports up to 50V output voltage\u003c\/li\u003e\n\u003cli\u003eHigh Current Capacity: Each output handles up to 500mA\u003c\/li\u003e\n\u003cli\u003eTTL \u0026amp;
