SKT 16

Product catalog summary

Overview

The document provides technical information on the SKT 16 Stud Thyristor, a line thyristor designed for power rectification and switching applications. It includes performance characteristics, typical applications, and mechanical dimensions.

Features and Applications

The SKT 16 is a thyristor bridge module suitable for use in rectifiers, SCR (Silicon Controlled Rectifiers), and power bridges.
Typical applications include power control and conversion in industrial and electronic systems.

Electrical and Thermal Characteristics

The document presents several key performance graphs and parameters:

Power Dissipation vs. On-State Current: Shows how power loss increases with current through the device.
Power Dissipation vs. Ambient Temperature: Illustrates thermal performance under varying environmental conditions.
Rated On-State Current vs. Case Temperature: Defines maximum current ratings depending on device temperature.
Recovered Charge vs. Current Decrease: Details the charge recovery behavior during turn-off.
Transient Thermal Impedance vs. Time: Provides insight into thermal response during transient conditions.
Thermal Resistance vs. Conduction Angle: Indicates how thermal resistance varies with conduction duration.
On-State Characteristics: Voltage-current relationship during conduction.
Surge Overload Current vs. Time: Defines the device's capability to withstand short-term current surges.
Gate Trigger Characteristics: Specifies gate current and voltage requirements for device triggering.

Mechanical Dimensions

The document includes detailed mechanical dimensions in millimeters for proper integration and mounting of the SKT 16 thyristor.

Important Notes and Recommendations

Specifications are indicative and do not guarantee component characteristics; testing in the actual application environment is necessary.
Adjustments may be required depending on the specific use case.
Use of SEMIKRON products in life support systems requires prior specification and written approval from SEMIKRON.
Consultation with SEMIKRON personnel is strongly recommended before deployment in critical applications.
