Basically an SCR ( Silicon Controlled Rectifier) which is also known by the name Thyristor works quite like a transistor. What SCR Stands for The device gets its name (SCR) due to its multi layered semiconductor internal structure which refers to the “silicon” word in the beginning of its name. The second part of the […]

SCR/Thyristor Circuit Configurations
Now in this article we will try to understand step by step how we can use this thyristor in practical work. That can be for controlling heavy loads like electric lamps, heaters, or motors and so on. So this part is more about real application and not only about theory. How We Trigger The Thyristor […]
BT169 SCR Datasheet [200 V, 0.5 A SCR]
The BT169 is a thyristor or SCR (Silicon Controlled Rectifier) that is commonly used for switching applications in low-power electronic circuits. It can be used for small signal, low current applications. Its size is very small just like a BJT. Here are the full technical specifications of the BT169: Electrical Specifications Pinout: The BT169 SCR […]

Simple SCR Battery Charger Circuit
In this post I have explained a simple yet accurate SCR triggered battery charger circuit which can be used effectively for charging all types of battery, which includes, lead acid battery, Ni-Cd battery banks, Li-Ion battery, etc. This SCR charger can be seen implemented in most automobile garages, and is very popular among auto mechanics, […]
SCR/Triac Controlled Automatic Voltage Stabilizer Circuit
In this article I have explained a relatively simple triac controlled automatic mains voltage stabilizer circuit, which uses logic ICs and a few triacs for controlling the mains voltage levels. Why Solid State Being solid state in design, the voltage switching transitions are very smooth with minimum wear and tear, resulting in efficient voltage stabilization. […]
