Description of ULN2003 Darlington Pair Transistor IC:
The ULN2003 is a high voltage and high current Darlington transistor arrays. ULN2003A consists of 7 NPN Darlington pairs with common-cathode clamp diodes for switching inductive loads. The collector-current rating of a single Darlington pair is 500 mA. The Darlington pairs can be paralleled for higher current capability. Applications include relay drivers, motor drivers, lamp drivers, display drivers (LED and gas discharge), line drivers, and logic buffers.

Darlington Transistor: What is it? (Darlington Pair)
Darlington transistor (also known as a Darlington pair) is an electronics component made via the combination of two BJTs (Bipolar Junction Transistor) connected in such a way that it allows a very high amount of current gain. This is achieved through a compounding amplification, whereby the current is amplified by the first transistor and then further amplified by the second transistor. As this compound structure is designed from two BJTs, this transistor is also known as “Darlington Pair”. This transistor behaves as a single unit transistor as it has only one emitter, collector, and base. The Darlington transistor was invented by Sidney Darlington in 1953.
How does the ULN2003 work?
The ULN2003 is a 16-pin IC. It has seven Darlington Pairs inside, where each can drive loads up to 50V and 500mA. For these seven Darlington Pairs we have seven Input and Output Pins. Adding to that we can a ground and Common pin.
What are Darlington transistors used for?
Darlington transistors are mainly used in switching and amplification applications for delivering a very high DC current gain. Some of the key applications are high and low side switches, sensor amplifiers and audio amplifiers.

ডার্লিংটন ট্রানজিস্টর (ডার্লিংটন পেয়ার নামেও পরিচিত) হল একটি ইলেকট্রনিক্স উপাদান যা দুটি বিজেটি (বাইপোলার জংশন ট্রানজিস্টর) এর সংমিশ্রণের মাধ্যমে এমনভাবে সংযুক্ত করা হয় যাতে এটি খুব বেশি পরিমাণে বর্তমান লাভের অনুমতি দেয়। এটি একটি যৌগিক পরিবর্ধনের মাধ্যমে অর্জন করা হয়, যার মাধ্যমে প্রথম ট্রানজিস্টর দ্বারা কারেন্টকে প্রসারিত করা হয় এবং তারপরে দ্বিতীয় ট্রানজিস্টর দ্বারা আরও প্রশস্ত করা হয়। যেহেতু এই যৌগিক কাঠামোটি দুটি BJT থেকে ডিজাইন করা হয়েছে, এই ট্রানজিস্টরটি “ডার্লিংটন পেয়ার” নামেও পরিচিত। এই ট্রানজিস্টরটি একটি একক ট্রানজিস্টর হিসাবে আচরণ করে কারণ এটিতে শুধুমাত্র একটি ইমিটার, সংগ্রাহক এবং বেস রয়েছে। ডার্লিংটন ট্রানজিস্টর 1953 সালে সিডনি ডার্লিংটন দ্বারা উদ্ভাবিত হয়েছিল।
