ULN2003A - High-Current Darlington Transistor Arrays

Download the ULN2003A datasheet PDF. This datasheet also covers the ULN2002A variant, as both devices belong to the same high-current darlington transistor arrays family and are provided as variant models within a single manufacturer datasheet.

General Description

The ULx200xA devices are high-voltage, high-current Darlington transistor arrays.

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.

Key Features

  • 500mA-rated collector current (single output).
  • High-voltage outputs: 50V.
  • Output clamp diodes.
  • Inputs compatible with various types of logic.
  • Relay-driver.
