A New Approach to Circuit Breaker Design Using Silicon Carbide Switches - Nov 21
Mechanical circuit breakers can be low cost with minimal losses, but they operate slowly and wear out. Solid state versions overcome the problems and are becoming increasing viable as replacements at...

600V IGBTs are smooth operators
A series of 600V trench-gate field-stop IGBT (insulated gate bipolar transistors) from STMicroelectronics have a smooth and tail-less turn-off characteristic, saturation voltage as low as 1.8V, and operate up to 175°C. They increase system energy efficiency, allow higher switching frequencies, and simplify thermal and EMI design, says the company.

The V series devices eliminate the conventional IGBT turn-off current tail and have ultra-thin die thickness to assist switching performance and improve thermal dissipation. The proprietary trench gate field-stop process provides improved thermal resistance and raises junction operating temperature, as well as allowing tight control over parameters such as saturation voltage, allowing safe paralleling of multiple IGBTs.

A co-packaged ultra-fast soft-recovery diode minimises turn-on energy losses. Diode-free variants are also available. The IGBTs are rated from 20 to 80A and are in production now in TO-3P, TO-3PF, TO-220, TO-220FP, TO-247 or D2PAK packages.
