Thyristors - SCRs - Modules

The VS-VSKH71/10 is a type of thyristor module with more current capacity than a single unit. It is used in many industrial applications, from medical devices to high-power industrial equipment. Designed and manufactured by Vishay, the VS-VSKH71/10 is a high-speed, reliable and cost-effective module.

A thyristor is a semiconductor switching device, making it possible to control a large amount of electricity with a small signal. It consists of two PN-junctions, connected in series and often referred to as a four-layer diode. It is designed for controlling and managing large amounts of varying voltage and current, with high-speed operations and a low on-resistance, making it a popular choice for high-power applications.

The VS-VSKH71/10 module is a type of thyristor, though it is more commonly referred to as a SCR (Silicon Controlled Rectifier). SCRs are similar to thyristors, but differ in the fact that they can be turned on with a gate input. In other words, they can be controlled by a small signal, making them useful for a variety of purposes, including motor control, power switching, lamp dimming, and heating and cooling.

When it comes to the VS-VSKH71/10, it is a module with more current capacity than a single unit. It is rated at 700A forward voltage, and is designed to handle up to 4A of forward current. The module is made with a ceramic substrate and a multiple PN junction, which helps it to control high amounts of current, with fast switching and low thermal dissipation.

In terms of applications, the VS-VSKH71/10 is commonly used in medical devices, induction motors and adjustable speed drives, energy meters, power supplies, and power grids. It is also suitable for a range of lighting and heating applications, for dimming lights and controlling temperature.

The core function of the VS-VSKH71/10 is the same as any other thyristor module: it allows a small voltage or current signal to control a much larger current. This is achieved through the principle of thyristor conduction. When a small current passes through the gate circuit (the control circuit), it causes electrons to flow from the positive terminal to the negative terminal, triggering a surge of current through the load (the controlled circuit). This surge is controlled by the thyristor, which has two terminals: the anode, and the cathode.

The VS-VSKH71/10 is designed for a variety of applications, and it is capable of providing reliable performance and cost-effectiveness. With its combination of power and versatility, the VS-VSKH71/10 is an excellent choice for industrial applications that require the control and handling of large amounts of electricity.
