Bipolar (BJT) Arrays

Darlington arrayOpen collectorRelay driverSOP-1850 V

ULN2803AG-JSM is an eight-channel, 50 V open-collector Darlington array for low-side switching of relays, solenoids, motors, displays, and similar loads.

Best for

  • Low-side relay and solenoid switching
  • Multi-channel inductive-load control
  • LED display and motor driver interfaces

Avoid if

  • A high-side switch or push-pull output is required
  • The load requires more than the specified voltage or current limits

Check before use

  • SOP-18 footprint and 1.27 mm pin pitch
  • Thermal dissipation with the intended number of active channels
  • Clamp-diode common connection and load supply voltage
