SCR Thyristor BT145-800 pinout, Features and Specifications

In this post, we are going to explain the SCR Thyristor BT145-800: A Silicon Controlled Rectifier (SCR), also known as a thyristor, is a device commonly used for controlling high power in electrical circuits. It acts as a switch that can turn on and conduct current when triggered, but it cannot turn off by itself until the current drops below a certain level. It has three terminals named Anode (A), Cathode (K), and Gate (G). The anode and cathode carry the main current, while the gate is used to control the switching action.
