2N5401 PNP Transistor (BJT)

Description

Introduction

The 2N5401 is a PNP high-voltage bipolar junction transistor (BJT) mainly used for amplification and switching applications. It is widely used in audio amplifiers, signal stages, and high-voltage circuits. It comes in a TO-92 plastic package (3 pins) and is the complementary pair of the 2N5551 (NPN transistor).

Features Explained

• High voltage support (150V) → high-voltage circuit e use kora jay
• Medium current (600mA) → small motor, signal stage chalanor jonne thik
• High gain (hFE 60–240) → small base current diye boro collector current control hoy
• Fast switching → digital switching circuit e use kora jay
• Low noise → audio preamp e clean sound dey
• Audio pre-amplifiers
• Signal amplification circuits
• High-voltage switching
• Push-pull amplifier (with 2N5551)
• General-purpose electronic circuits
• Telecommunication circuits
