Thyristors are a type ofsemiconductor device that is widely used as switches, rectifiers, and voltage regulators. The VS-T90RIA60 is a module from the Vishay Siliconix range of thyristors, that includes SCRs and Diodes. This particular module consists of two connections and is based on a thyristor construction.

The VS-T90RIA60 is a two-terminal thyristor module specifically designed for industrial applications. It is a high power semiconductor device that integrates two 90A thyristors, input and output snubbers and EMI suppression devices, along with static and dynamic connectors. This device is rated at 90A peak current, with a 50V blocking voltage and an operating temperature range of -55°C to 175°C. It is designed to offer maximum efficiency and reliable operation with minimal heat generation.

The major application field of the VS-T90RIA60 includes motor drive and control, induction heating, uninterruptible power supplies (UPS), adjustable speed drive system, electronic ballast, and high power switching applications.

The working principle of the VS-T90RIA60 is simple yet effective. When the voltage across the device exceeds the trigger voltage, the thyristor turns on and the module switches on the device. The current through the device is then controlled by the current driver. When the current rises above the rated current, the load is shut off by the module. This ensure that the load current and voltage remain consistent so that the device remains stable.

The VS-T90RIA60 module also offers several safety and protection features. It has an overvoltage protection feature which prevents the device from being damaged due to overvoltage. It also has overcurrent protection which prevents the device from being damaged due to overcurrent. Lastly, it has short circuit protection which prevents the device from being damaged due to short circuits.

The VS-T90RIA60 module is a cost-effective and reliable device for high power switching applications.
