FEATURES & SPECIFICATIONS
- IC name: ULN2003ADR
- Darlington transistor
- SOP16
- Easy to Use
- SMD
- Weight : 0.14 g
The ULN2003ADR is a versatile NPN Darlington transistor array in a compact SOP16 package, designed for high-voltage and high-current applications. With a 500mA-rated collector current per output and high-voltage outputs of up to 50V, it’s ideal for relay drivers, motor drivers, lamp drivers, and display drivers.
Featuring seven NPN Darlington pairs, each with built-in output clamp diodes, it efficiently switches inductive loads while ensuring reliability. The collector-current rating allows for parallel operation, increasing current capability for demanding applications.
Inputs are compatible with various logic types, including TTL and CMOS devices, thanks to integrated base resistors tailored for different voltage ranges. The ULN2003ADR is designed to handle input currents safely, making it suitable for a wide range of applications where precision and reliability are paramount.
Whether you’re driving relays, motors, lamps, or displays, the ULN2003ADR offers robust performance and compatibility, making it a go-to solution for electronic projects requiring efficient and reliable switching capabilities.

Questions and Answers
You are not logged in
The ULN2003ADR is a Darlington transistor array with 7 NPN channels, used to drive high-current loads (like relays, stepper motors, LEDs) from low-current logic signals. It comes in a SOP-16 surface-mount package.
It’s used for relay driving, stepper motor control, LED matrix driving, and solenoid activation, especially in systems where TTL/CMOS logic must control higher-voltage or higher-current loads.
Each channel can sink up to 500 mA (with proper thermal management) and handle up to 50V on the output. Channels can be paralleled for more current.
Yes, each output has an integrated freewheeling (clamp) diode, which protects the circuit from voltage spikes when driving inductive loads like motors or relays.
