How do you find the transistor equivalent?

How do you find the transistor 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.

What is transistor equivalent circuit?

The transistor equivalent circuit can now be evolved with the two-pole formulae for the transistor fundamental circuit in Fig. 3.1, the common emitter circuit. In the transistor, however, the input parameters are dependent on this resistance. We thus have the transistor voltage equivalent circuit as shown in Fig.

What are the factors to consider in substituting transistor?

Depending on the application and type of the original transistor, the basic areas of concern are the voltage, power, current, switching speed and amplification characteristics of the substitute. Other areas that may also be important include the lead locations on the transistors and the mounting options.

Can I use BC547 instead of 2N2222?

You can update the circuit at anytime, you can replace the 2n2222 NPN transistors with the BC547 and it will have no negative effect on the project.

Where is 2n2222A transistor used?

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.

What do the numbers in a transistor outline mean?

A Transistor Outline number, or TO, refers to a transistor’s physical size, shape, and mounting style. Some TO numbers are shown here: The transistor outline doesn’t usually tell you which of the three transistor leads connects to its Base terminal (B), its Emitter terminal (E), or its Collector terminal (C).

What is the maximum voltage of a C331?

Contact Form: C231S: 1a / C331S: 2a Load Voltage: 350V Maximum MDMA – Connectors, Electrical, Rectangular, Microminiature

Which is the first spec to look for in a transistor?

Use your browser to search for the transistor’s JEDEC type, or use a search engine like AllDataSheet.com. The first spec to consider is the Transistor Outline. This is the only spec you can actually see. A Transistor Outline number, or TO, refers to a transistor’s physical size, shape, and mounting style.

Can a substitute transistor be as high as the original?

Choose a substitute transistor with a maximum power rating at least as high as the original. Current gain is only occasionally significant when choosing a substitute transistor. Actual circuit gain depends on other components. But if the original transistor has a high gain, try to match it.
