Plastic-Encapsulate Darlington Transistors

ULN2003A Darlington Transistor (NPN)

3 Features

1 Introduction

ULN2003A is a high voltage, high current Darlington

transistor array. Each device consists of seven NPN

Darlington pairs that can be output independently.

These Darlington pairs have common emitter poles

that support high voltage output with a common

cathode clamp diode for switching inductive loads.

The input and output of the clamp diode are relatively

fixed to simplify the layout of the printed circuit board.

The collector current of a single Darlington pair is

rated at 500mA, and parallel Darlington pairs provide

a higher current.

Lamp Drivers

Each Darlington pair of ULN2003A devices has a

2.7kΩ series base resistance that works directly with

TTL or CMOS devices. This device is often used to

drive a variety of loads, such as DC engine, LED

display light, high power cache and general logic

circuits such as TTL, 5V CMOS, etc.
