Wolfspeed has cut switch resistance to 3.6mΩ in its 1,200V all-silicon carbide half-bridge. Called CAS325M12HM2, it has seven 1.2kV 25mΩ mosfets and six 1.2kV 50A  Schottky diodes from Cree in each per switch position. A companion gate driver, CGD15HB62LP, is designed specifically to work with the module, including fitting within a 62mm mounting footprint. Power package inductance is 5nH, …

We are pleased to announce that you can now add cost allocation tags to your AWS Directory Service directories. Tags make it easier for you to allocate costs and optimize spending by categorizing and grouping AWS resources. For example, you can use tags to group resources by administrator, application name, cost center, or a specific project. 

You can now use Docker Compose version 2 YAML files with the Amazon EC2 Container Service CLI (Amazon ECS CLI) to create an Amazon ECS service.
