DESCRIPTION
This series of products in a hermetic package is specifically designed for use at power
switching frequencies in excess of 100 kHz. This series of ultra fast rectifiers is packaged
in a small easy-to-use JEDEC TO-257AA package, replacing conventional DO-4 and TO-3
packaging. These devices are ideally suited for demanding applications where small size
and a hermetically sealed package are required. All devices are available Hi-Rel screened
in Omnirel’s facility. (See Omnirel’s OM803 Hi-Rel screening program.)
