Vishay Thyristor 1200 V, 172 A Rated Average On-State Current, Surge Current 2.18 kA, Maximum Gate Trigger VS-110RKI120

Vishay VS-110RKI120 Thyristor is a solid-state semiconductor device featuring a four-layer alternating N and P-type material design. It acts as a bistable switch conducting when triggered via the gate current, then maintaining conduction while forward biased. This device is classified as a Phase Control Thyristor (PCT) and housed in a TO-94 package with screw mounting, enabling efficient heat dissipation.

Rated for a repetitive peak reverse voltage of 1200 V and a maximum on-state current of 172 A, it is robust for high power control scenarios. The surge current rating of 2.18 kA supports transient events encountered in industrial applications.

With a gate trigger current maximum of 180 mA and a trigger voltage of 2.5 V, it allows precise control and reliable triggering. The maximum operating temperature reaches 140°C, while the minimum temperature tolerates down to -40°C, making it suitable for varied climatic conditions.

This Vishay thyristor exhibits a low peak on-state voltage of 1.57 V and a maximum holding current of 200 mA, enhancing efficiency and reducing power loss during operation. The repetitive peak off-state current is minimal at 20 mA, minimizing leakage power consumption.

Common applications include battery chargers, welding machines, plating equipment, regulated power supplies, and motor speed and temperature control circuits. These industrial use cases benefit from the high durability and precision control offered by this device.

The device utilizes a TO-94 package type designed for screw mounting for secure and stable installation. Its high surge current rating of 2.18 kA allows it to handle fault conditions and transient power surges effectively.

The wide operating temperature range enhances its usability in harsh industrial environments. Designed without automotive certification, it primarily targets industrial and electrical applications. The product is new, manufactured in India, and belongs to the VS-11 series.

This Vishay VS-110RKI120 thyristor represents a reliable and efficient power control component suitable for demanding industrial environments. Explore more high-quality semiconductors and Thyristors in the Electronics & Electricals category on EnvMart.
