Product overview
Description
The 1N5811 is an ultrafast rectifier housed in the ceramic LCC-2B package. This surface mount package is hermetically sealed, and its footprint is fully compatible with industry standards, as such the D5B.
The 1N5811 rectifier is characterized in total ionizing dose at high dose rate to be used in Rad-Hard applications.
Its full planar technology allows superior performances and high reliability up to 175°C junction temperature.
This diode is ESCC qualified, which makes it eligible for use in space programs. It is typically used in switching mode power supplies, high frequency DC-to-DC converters or low voltage step-down chopper drive to perform secondary rectification, free wheeling diode or reverse polarity protection.
