What is the replacement of transistor?

The first factor that should be considered when substituting a transistor is the charge of the transistors. A transistor that has a positive-negative-positive charge (PNP) must be substituted with a PNP type transistor. Likewise, a negative-positive-negative (NPN) transistor must be substituted with an NPN transistor.

Is emitter and collector interchangeable?

Are the collector and emitter terminals of a bipolar transistor interchangeable? No. Transistors are designed to provide the optimum performance when they are correctly connected.

Which transistor can be used in place of 2N3904?

2N3904 equivalent Given below is the list of popular transistors which can be used as a replacement for 2N3904: BC537, BC538, 2N4401, and P2N2222A. BC547 and BC548 are functionally equivalent transistors.

What is a 2N2222 NPN?

The 2N2222 is a common NPN bipolar junction transistor (BJT) used for general purpose low-power amplifying or switching applications. It is designed for low to medium current, low power, medium voltage, and can operate at moderately high speeds. It was originally made in the TO-18 metal can as shown in the picture.

What is BC107 transistor?

The BC107 and BC107B are silicon planar epitaxial NPN transistors in TO-18 metal case. They are suitable for use in driver stages, low noise input stages and signal processing circuits of television receivers. The PNP complementary types are BC177 and BC177B respectively.

What type of transistor is C1815?

Also known as 2SC1815, the C1815 is a bipolar junction NPN transistor widely used in commercial and educational projects. It is designed for audio frequency amplification and high-frequency oscillator(OSC). The collector-base voltage of the C1815 is 50V, hence it can be easily used in circuits using under 50V DC.

How do you know if a transistor is equivalent?

Step by step instructions:

1. Choose a transistor of the same polarity: The first major selection criterion is whether the transistor is PNP or NPN.
2. Select a replacement transistor of the same material: Most transistors are either silicon or germanium.

Will the transistor work if we interchange the emitter and collector?

No, we cannot interchange emitter and collector of a transistor due to the following reasons: In a transistor, the emitter is heavily doped and collector is comparatively lightly doped. In a transistor, the contract area of the emitter-collector junction is larger than that of the emitter-base junction.
