Overview

The ULN2803A is a high-voltage, high-current Darlington transistor array. The device consists of eight npn Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads. The collector-current rating of each Darlington pair is 500 mA. The Darlington pairs may be connected in parallel for higher current capability.

Key Features:

  • High-Voltage Outputs up to 50 V
  • Output Clamp Diodes
  • Relay Driver Applications
  • Compatible with ULN2800A Series
  • 500-mA Rated Collector Current (Single Output)
  • Inputs Compatible With Various Types of Logic
