Introduction

The 2N551 is a general-purpose NPN silicon BJT transistor used for amplification and low-power switching in older analog circuits. It belongs to early generation transistors (TO-5 metal can type), mainly used in audio, RF, and signal amplifier circuit.

Simple Explanation (Easy Language)

• NPN transistor → base e small current dile output current control kore
• 60V support → medium voltage circuit e use kora jay
• 200mA current → small load handle korte pare
• Metal body → heat bhalo tolerate kore, but old design
