Description
BC547 হলো একটি NPN সিগন্যাল ট্রানজিস্টর যা ছোট লোড চালানো, সিগন্যাল সুইচিং এবং অডিও/লো-পাওয়ার অ্যাম্প্লিফিকেশনের জন্য ব্যবহার করা হয়। এটি সর্বোচ্চ 45V ভোল্টেজ, 100mA কারেন্ট সহ্য করতে পারে এবং এর গেইন (hFE) প্রায় 110–800 পর্যন্ত হতে পারে। ছোট আকার (TO-92 প্যাকেজ), কম দামে হাজারো প্রজেক্ট তৈরীর সুবিধার কারণে এটি ইলেকট্রনিক্স প্রজেক্টে খুব জনপ্রিয়।
