What type of transistor is 2N3906?

The 2N3906 is a commonly used PNP transistor. It very much similar to the bc557 transistor except for that it has high collector to emitter voltage and hence high voltage loads can be toggled. This transistor has only a gain value of 300, hence not suitable for amplifier circuits.

What are BJT parameters?

Mainly three parameters are used to define BJT transistor performance. Current Amplification factor, Base Transport Factor, Emitter Injection Efficiency parameters shows the performance of NPN transistor and PNP transistor.

What is VBE and VCE?

VCE= DC voltage between collector and emitter w.r.t ground. VBB=DC voltage at the base w.r.t ground. VBE= DC voltage b/w base and emitter w.r.t ground. In different configuration, that is CC, CB, CE , DC voltage is applied at different terminals and correspondingly we have the voltages.

What is 2n2222a transistor?

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 are transistor parameters?

A parameter is a characteristic or property of a transistor which identifies it and distinguishes it from another similar transistor. In choosing a particular transistor to do a specific job, a comparison of parameters is the means by which the most suitable component can be selected.

What is alpha and beta in BJT?

Alpha of a transistor is the current gain in common base configuration defined as the ratio of change in collector current to change in emitter current while beta is the current gain in CE configuration. It is defined as the change in collector current to base current.

What is transistor VCE?

The transistor parameter “Vce” signifies the voltage measured between the collector and emitter, which is extremely important because the voltage between the collector and the emitter is the output of the transistor.

What is the typical h-parameters of a BJT?

Typical values are h re = 1 x10 -4, h oe typical value 20uS, h ie typically 1k to 20k and h fe can be 50 – 750. The H-parameters can often be found on the transistor datasheets. The table below lists the four h-parameters for the BJT in common base and common collector (emitter follower) mode.

How to drive the h-parameter model for a transistor?

To drive the h-parameter model for a transistor, we consider the basic CE amplifier circuit of figure 1. The variable i B, i C, v B (=v BE) and v C (v CE) represent the instantaneous total values of currents and voltages. The input current i B and output voltage v C are chosen as the independent variables.
