Darlington ArrayDriver ICInductive Load Driver

The ULN2003ANSR is a 7-channel Darlington transistor array optimized for driving inductive loads like relays and motors.

Best for

  • Inductive load switching
  • Relay driving
  • Logic-to-power interfacing

Avoid if

  • High-frequency switching applications
  • Current requirements exceeding 500mA per channel

Check before use

  • Ensure the COM pin is connected to the load supply voltage for flyback protection.
