Vishay Thyristor Rated 1200 V, 25 A Average On-State Current, 60 mA Gate Trigger Current, 440 A Surge Current VS-25RIA120S90

Vishay VS-25RIA120S90 is a silicon-controlled rectifier (SCR) thyristor designed to handle high current and voltage loads in demanding industrial and electronic applications. This phase control thyristor supports a maximum repetitive peak reverse voltage (VDRM) of 1200 V and a rated average on-state current of 25 A, making it suitable for control circuits in battery chargers, welders, plating equipment, and temperature and speed control systems.

Housed in a TO-48 package with a screw mount type, it provides reliable mechanical stability and easy installation. This device features a maximum gate trigger current of 60 mA and a maximum gate trigger voltage of 2 V, allowing precise switching control and efficient operation. Its peak on-state voltage is 1.7 V, helping to minimize power dissipation during conduction.

The thyristor functions over a broad temperature range, from -65°C up to 125°C, suitable for harsh industrial environments. A holding current of 130 mA ensures stable latching, while the repetitive peak off-state current is limited to 10 mA, contributing to safety and robustness. With 2 pins, this component is optimized for phase control applications without automotive certification.

As part of the VS-25RIA series, this Vishay thyristor embodies high quality and precision manufacturing standards. It provides solid-state switching capabilities for complex electronic circuits requiring fast and reliable control.
