2N5551 PACK OF 10

2N5551 - NPN Bipolar Junction Transistor

The 2N5551 is a high-voltage, low-current NPN bipolar junction transistor designed for general-purpose amplification and switching applications. It is housed in a compact TO-92 package, making it ideal for through-hole PCB designs where space and thermal constraints are considerations.

Engineered to handle collector-emitter voltages up to 160V, the 2N5551 is suitable for use in high-voltage analog circuits, such as audio amplifiers, signal processing stages, and voltage regulation systems. It delivers a continuous collector current of up to 600 mA and exhibits a DC current gain (hFE) in the range of 30 to 300, depending on the operating current and temperature conditions.

Key Features:

• High voltage handling: Vce = 160V

• Moderate collector current: Ic = 600 mA

• Wide DC current gain range

• Low saturation voltage for efficient switching

• Complementary to 2N5401 (PNP type)

• Standard TO-92 package

Applications:

• Signal and audio amplifiers

• High-voltage switching circuits

• Voltage regulator circuits

• General-purpose transistor for industrial and consumer electronics

Package Type: TO-92 (Plastic Through-Hole)
