Component

Darlington ArrayDriver ICRelay Driver

The ULN2402A is a 4-channel Darlington transistor array designed for high-current, high-voltage switching applications like relays and motors.

Best for

  • Relay driving
  • Stepper motor control
  • LED display driving

Avoid if

  • Applications requiring currents exceeding 500mA per channel without parallel configuration

Check before use

  • Ensure proper pull-down resistors are used if the driving MCU has internal pull-ups
