SKT 10

Product catalog summary

Overview

The document presents technical information on the SKT 10 Stud Thyristor, a line thyristor module designed for power rectification and switching applications.

Features and Applications

Designed as a thyristor bridge module (SCR bridge).
Typical applications include power rectification and controlled switching in industrial and power electronics systems.

Electrical and Thermal Characteristics

The datasheet includes multiple graphical representations detailing the device's performance parameters:

Power Dissipation vs. On-State Current: Shows how power loss varies with conduction current, critical for thermal management.
Power Dissipation vs. Ambient Temperature: Indicates the impact of environmental temperature on device losses.
Rated On-State Current vs. Case Temperature: Defines maximum current ratings depending on the device temperature.
Recovered Charge vs. Current Decrease: Provides insight into switching behavior and charge recovery during turn-off.
Transient Thermal Impedance vs. Time: Details the thermal response of the device to transient loads.
Thermal Resistance vs. Conduction Angle: Shows how thermal resistance varies with conduction angle, important for pulse operation.
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 reliable triggering.

Mechanical Dimensions

Dimensions are provided in millimeters to assist with mechanical integration and mounting.

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 in life support systems requires prior specification and written approval from SEMIKRON.
Consultation with SEMIKRON personnel is strongly recommended before critical applications.
