Specification

Description

The 2N5551 NPN transistor is a general-purpose amplifier and switching transistor used in electronic circuits. It's a low-to-medium power device with moderate current and voltage ratings, making it suitable for a wide range of applications. This transistor is commonly available in TO-92 packaging, which makes it easy to handle and integrate into circuit designs.

Features:

NPN Configuration: The 2N5551 is an NPN transistor, which means it operates with a positive voltage on its collector relative to its emitter.

Low Power: It's designed for low-to-medium power applications, typically handling currents in the range of a few hundred milliamperes (mA).

Moderate Voltage Ratings: The transistor can handle moderate voltages, often up to around 160V in collector-emitter voltage (VCE) ratings.

Gain: It offers moderate current gain (hFE) values, making it suitable for both amplification and switching purposes.

Compact Packaging: The TO-92 packaging makes it easy to use on breadboards and in prototyping circuits.

Applications:

Amplification: The 2N5551 is commonly used as a general-purpose amplifier in audio circuits, oscillators, and low-frequency signal amplification stages.

Switching Circuits: Due to its moderate current and voltage ratings, it's suitable for small to medium-sized switching applications. For example, it can be used in relay drivers, LED drivers, and motor control circuits.
