What is a S9014?

The SS9014 is a low signal and low noise NPN transistor with a good hfe value of upto 1000 of high linearity this makes this transistor an ideal choice for designing Audio Frequency (AF) amplifiers or pre-amplifiers.

How does a NPN transistor work in a circuit?

The NPN transistor amplifies the weak signal enter into the base and produces strong amplify signals at the collector end. In NPN transistor, the direction of movement of an electron is from the emitter to collector region due to which the current constitutes in the transistor.

Can NPN transistor be used as amplifier?

When NPN transistor is used as an amplifier, majority charge carrier electrons of N-type emitter move from emitter to base and then base to collector.

Are NPN transistors interchangeable?

Answer: NPN and PNP transistors are interchangeable if you remember one simple rule: A bipolar transistor is essentially two back-to-back diodes with the base being the common connection.

What type of transistor is S9014?

NPN epitaxial silicon planar transistor
The S9014 is an NPN epitaxial silicon planar transistor designed for use in the audio output stage and converter/inverter circuits.

What are NPN transistors used for?

NPN transistors are mainly used in switching applications. Used in amplifying circuit applications. Used in the Darlington pair circuits to amplify weak signals. NPN transistors are used in the applications where there is a need to sink a current.

Why do we use NPN transistor?

NPN transistors are used in applications where a current sink is required. Some classic amplifier circuits, such as ‘push-pull’ amplifier circuits, make use of this component. In temperature sensors, for example. Applications with extremely high frequency.

How does a NPN transistor work as an amplifier?

A transistor acts as an amplifier by raising the strength of a weak signal. The DC bias voltage applied to the emitter base junction, makes it remain in forward biased condition. This forward bias is maintained regardless of the polarity of the signal.
