The TO-220 FullPAK Wide Creepage replaces frequently used workarounds to increase creepage distance such as silicon potting, the usage of sleeves, pre-bending of leads or others. Offering a better alternative to workarounds, customers profit from reduced system costs when implementing the new package.
Wide spread pins prevent failures
The TO-220 FullPAK Wide Creepage package targets open frame power supplies such as TV adapters where dust can enter the case through air vents. These dust particles can reduce the effective creepage between pins over time which may lead to high voltage arcing. The TO-220 FullPAK Wide Creepage package comes with a pin distance of 4.25mm instead of the prevailing 2.54mm found in a standard TO-220 FullPAK package.
The other outer dimensions of the new package are almost identical to the TO-220 FullPAK. Additionally, the Wide Creepage package shows all the well-known benefits of a standard FullPAK, predominantly its excellent isolation behaviour as well as the assembly automation ability.
The TO-220 FullPAK Wide Creepage package is available now.
