SCRs are four-layer semiconductor power switches used primarily in heavy industry applcations. The S402ES SCR is a popular choice for many industrial applications, such as machine automation and power control, because it offers reliable operation and is easy to use. This article will provide an overview of the S402ES SCR\'s application fields and working principle.The S402ES is a 4-quadrant TRIAC that is used to control DC, AC and pulse loads. It is part of a family of SCRs known as “Thyristors” – the term “Thyristor” comes from the Greek words thyris (gate) and storos (keeper). The S402ES is a four-layer, sealed vacuum-encapsulated, bidirectional semiconductor switch. It is a rugged, high-efficiency switch, with voltage ratings ranging from 25 Volts to 400 Volts and current ratings from 10 Amps to 90 Amps.The S402ES is a reverse-blocking SCR, meaning that it can be used to block reverse current. When voltage is applied to the gate, current flows through the SCR and it is said to be “ON”. When the current flow stops, the SCR is said to be “OFF”. Due to its bidirectional capability, the SCR can be used to switch either AC or DC current. The SCR can also be used to modulate current and is often used to control inverters and other AC power sources.The S402ES SCR is commonly used in applications such as motor control, relays, power control and other load switching applications. It is also used in AC circuit breakers, overvoltage protection devices, static relays and other applications requiring fast, reliable switching.The working principle of the S402ES SCR is based on the fact that it is a bidirectional semiconductor switch. When a voltage is applied to the gate terminal, a small current flows into the SCR’s anode. This current flow results in an avalanche breakdown of the p-n junction between the anode and the cathode, allowing a larger current to flow through the SCR. This high current flow is then used to control the load.The S402ES SCR is a versatile and reliable switch and is used in many industrial applications. Its bidirectional capability allows it to be used in a variety of applications, and its rugged design ensures it can withstand high current and voltage applications. With its wide range of voltage and current ratings, the S402ES is a great choice for many industrial projects.
