International Rectifier 30WQ10FN

Semiconductor package is a carrier / shell used to contain and cover one or more semiconductor components or integrated circuits. The material of the shell can be metal, plastic, glass or ceramic.

Current rating is the maximum current that a fuse will carry for an indefinite period without too much deterioration of the fuse element.

The rated output current is the maximum load current that a power supply can provide at a specified ambient temperature. A power supply can never provide more current that it's rated output current unless there is a fault, such as short circuit at the load.

the amount of voltage needed to get current to flow across a diode.
