• The 2N5551�is an NPN amplifier Transistor with an amplification factor (hfe) of 80 when the collector current is 10mA. It also has decent switching characteristics (Transition frequency is 100MHz) hence can amplify low-level signals. Due to this feature, the transistor is commonly used for amplification of audio or other low power signals. So if you are looking for an NPN transistor for you amplifier circuit, then this transistor might be the right choice.

Applications

• Low power amplifiers
• Current amplifiers
• Small signal boosters
• Audio or other signal amplifiers
• Darlington pair
