DESCRIPTION
This series of products in a hermetic package is specifically designed for use at
power switching frequencies in excess of 100 kHz. The series combines two high
efficiency devices into one package, simplifying installation, reducing heat sink
hardware, and the need to obtain matched components. These devices are ideally
suited for Hi-Rel applications where small size and a hermetically sealed package
are required. Common anode configurations are also available. Common cathode
is standard.
