Product Details:

Overview

The ULN2003D1 is a Darlington transistor array manufactured by STMicroelectronics. This device features seven NPN Darlington pairs with high-voltage outputs and common-cathode clamp diodes for switching inductive loads. It is designed for surface mount assembly and comes in a 16-SO package.

Key Features

  • Seven Darlington transistors per package
  • High-voltage outputs (50V)
  • Output clamp diodes
  • Surface mount 16-SO package

Applications

This transistor array is commonly used in interface applications requiring high current or voltage drive. Its integrated diodes make it suitable for controlling inductive loads. Typical uses include:

  • Relay drivers
  • Stepper motor control
  • Lamp drivers
