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...

Six devices in two-pin package expand Infineonís CoolSiC family
The surface mount packages enable designs to be more compact and more cost effective, says the company. The D²PAK two-pin package enhances safety margins by eliminating the middle pin to offer 4.7 mm creepage and 4.4 mm clearance distance.

Suitable applications are industrial power supplies, and DC charging stations, uninterruptable power supplies (UPS) and solar string inverters.

The diodes use the company’s ,technology G5, which is claimed to offer best-in-class forward voltage and high surge current capability. It is also claimed to prevent reverse recovery losses and allows for temperature-independent switching behaviour. These features can streamline designs with lower cooling requirements and smaller magnetics when used at higher switching frequency. The diodes are rated from 2.0 to 20A.

According to the company, using the SiC diodes in the D²PAK two-pin package improves power density and reliability compared to Si alternatives.  

The CoolSiC Schottky diodes 1,200 V G5 are available for order now.
