Question

What are transistor parameters?

Answer 1

A transistor is a three-terminal semiconductor device that is used for amplification and switching purposes in an electronic circuit.

Out of the three terminals, one pair of terminals is used to supply the input voltage/current, and the other pair of terminals is used to obtain the controlled output current/voltage.

The parameters of the transistor are:

1. Current gain: The current gain of a transistor is the measure of the ability of the transistor’s amplification property. It is usually denoted by β. The current gain is the ratio of the base current to the collector current
2. Collector-Emitter voltage: The Collector-Emitter voltage is the maximum voltage that a collector-emitter junction voltage that a transistor can handle.
3. emitter-base voltage: Emitter-base voltage is the measure of the maximum voltage that can be applied across the emitter-base voltage.${\mathrm{V}}_{\mathrm{EBO}}$ and is relatively smaller than ${\mathrm{V}}_{\mathrm{CEO}}$.
4. Collector current: Collector current is the measure of the maximum current that can flow through the collector.
