Product Overview

The ULN2003AIDG4 is a 50V high-voltage, high-current Darlington Transistor Array. Each consists of seven NPN Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads. The collector-current rating of a single Darlington pair is 500mA. The Darlington pairs can be paralleled for higher current capability. Applications include relay drivers, hammer drivers, lamp drivers, display drivers (LED and gas discharge), line drivers and logic buffers.
  • 500mA Rated collector current (single output)
  • High voltage output (50V)
  • Output clamp diodes
  • Inputs compatible with various types of logic


Power Management, Industrial


This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
