DESCRIPTION
This series of products in a hermetic surface mount 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 Military applications where small size and a hermetically sealed
package is required. Common cathode is standard.
