Product Description

Vishay VS-81RIA120 is a high-quality Thyristor Module SCR designed for heavy-duty industrial power control. Rated at 1200 V repetitive peak reverse voltage and capable of handling an average on-state current of 80 A, it is ideal for use in applications demanding reliable and efficient switching.

The device is constructed with four alternating layers of N and P-type semiconductors arranged in the Silicon-Controlled Rectifier (SCR) configuration. It triggers when a gate current is applied and maintains conduction as long as forward voltage bias is present. The module's maximum gate trigger current is 270 mA, with a holding current of 200 mA, allowing effective control over switching.

Encapsulated in a TO-209 package featuring a screw mount and an electrically isolated base plate, the module ensures ease of installation and effective heat dissipation. It supports operations over a wide temperature range from -40°C to 125°C, suitable for harsh industrial environments.

This module is beneficial in phase control applications within battery charging, welding, plating, regulated power supplies, and temperature or speed control circuits due to its robustness and performance specifications.

Surge Current Rating of 1.99 kA enables management of transient conditions. Low peak on-state voltage of 1.6 V ensures efficient operation. Repetitive peak off-state current of 15 mA minimizes leakage current. 4-pin configuration supports stable electrical connections.

Manufactured in India, ensuring compliance with local standards.

This Vishay Thyristor Module VS-81RIA120 is a reliable choice for laboratory, industrial automation, manufacturing, HVAC, and electric power applications requiring sturdy and precise power switching semiconductor devices.
