Semikron Danfoss Dual Thyristor Module 1200 V 300 A 150 mA 370 A 2.2 V SKKT 57/12 E

Semikron Danfoss SKKT 57/12 E is a Dual Thyristor Module specifically engineered for demanding power control applications. This SCR (Silicon-Controlled Rectifier) based module incorporates two thyristors with an isolated base plate and a G-12 package type.

It is designed to handle high current load with a rated average on-state current of 300 amperes and repetitive peak reverse voltage of 1200 volts. The surge current rating of 370 amperes ensures it withstands transient overloads effectively.

The module operates reliably across a broad temperature range from -40°C to 150°C, making it suitable for industrial and commercial equipment exposed to harsh environments.

Gate trigger current is optimized at a maximum of 150 mA with a trigger voltage of up to 3 volts, facilitating precise switching control. Its maximum holding current is 250 microamperes, contributing to stable conduction states and minimizing false triggering.

Due to its low peak on-state voltage of 2.2 volts, the module exhibits efficient power loss characteristics during conduction cycles. The panel mount configuration and 4-pin design allow for straightforward assembly in power electronic circuits.

Applications of the SKKT 57/12 E module include battery chargers, welders, regulated power supplies, and temperature or speed control circuits, particularly in industrial automation and manufacturing sectors.

Manufactured in Slovakia, this module complies with UL recognized component standards, though it does not hold additional certifications or automotive standards. High surge current rating supports transient electrical loads reliably.

Wide operational temperature range ensures functionality under extreme conditions. Compact G-12 package facilitates integration into modular power systems. Optimized gate and holding current specifications for robust switching performance.

Low conduction voltage drop enhances energy efficiency. Panel mounting offers ease of installation and replacement. Explore more power semiconductor solutions at EnvMart for industrial and electronic component needs.
