A module is a separate unit of software or hardware. Typical characteristics of modular components include portability, which allows them to be used in a variety of systems, and interoperability, which allows them to function with the components of other systems.
The symbol for SCR is also shown in figure which is very familiar to Diode's Symbol. An SCR is a short form for Silicon Controlled Rectifier, Which is a three terminal semiconductor device.This device is used for rectification, regulation and inversion etc. It is also used as a controlled switch in high rating instruments. That is why this device has such importance.It is a Unidirectional Power Switch.he symbol for SCR is also shown in figure which is very familiar to Diode's Symbol.

Thyristor Basics. In many ways the Silicon Controlled Rectifier, or the Thyristor as it is more commonly known, is similar to the transistor. It is a multi-layer semiconductor device, hence the âsiliconâ part of its name.It requires a gate signal to turn it âONâ, the âcontrolledâ part of the name and once âONâ it behaves like a rectifying diode, the ârectifierâ part of the name.t is a multi-layer semiconductor device, hence the âsiliconâ part of its name.
