ULN2003 product

ULN2003

Up to 2 Amps

Darlington ArrayDriver ICMotor Driver

The ULN2003 is a versatile 7-channel Darlington transistor array designed for driving high-current loads like relays and stepper motors from low-voltage logic.

Best for

  • Driving relays
  • Stepper motor control
  • LED matrix driving

Avoid if

  • High-frequency switching applications (due to Darlington delay)
  • Loads exceeding 500mA per channel

Check before use

  • Supply voltage for inductive loads
  • Thermal dissipation at high currents
