Main Features and Advantages
Superior Power Handling and Voltage Capability: The ABB 5STP26N6500 delivers an industry-leading 6500V blocking voltage capability combined with an average current rating of 2880A, making it one of the most powerful phase control thyristors available in its class. This exceptional power density allows system designers to achieve higher voltages and currents with fewer series-connected devices, reducing overall system complexity and improving reliability. The ABB 5STP26N6500 is designed with a conservative voltage margin, ensuring robust performance even under transient overvoltage conditions common in industrial power conversion systems.
Patented Free-Floating Silicon Technology: The ABB 5STP26N6500 incorporates ABB’s proprietary free-floating silicon technology, which eliminates mechanical stress on the silicon wafer that can lead to premature failure in conventional thyristor designs. This advanced construction ensures that the ABB 5STP26N6500 maintains consistent electrical characteristics throughout its operational life, even under the thermal and mechanical stress of repetitive high-power cycling. The result is a device that offers superior thermal fatigue resistance and an extended operational lifetime, significantly reducing maintenance costs and system downtime.
Optimized On-State Characteristics: The ABB 5STP26N6500 features a low on-state voltage drop of approximately 2V at 3000A, coupled with a threshold voltage of 1.12V and an on-state slope resistance of just 0.29mΩ. This optimized characteristic ensures that the ABB 5STP26N6500 minimizes conduction losses, improving overall system efficiency and reducing cooling requirements. Matched Qrr and VT values are available for series and/or parallel connections, enabling the ABB 5STP26N6500 to be configured in high-power assemblies with excellent current and voltage sharing.
Robust Surge Current Capability and Fault Tolerance: The ABB 5STP26N6500 is capable of withstanding non-repetitive surge currents up to 65kA for a 10ms half sine pulse. This surge rating, combined with a limiting load integral (I²t) of 10125 kA²s, ensures that the ABB 5STP26N6500 can survive severe fault conditions such as short circuits or misfiring in adjacent devices, providing a crucial level of protection for the entire converter system. This ruggedness is essential for applications where system reliability and protection are paramount.
