| OM5250SM OM5251SM OM5252SM OM5254SM OM5256SM OM5253SM OM5255SM ISOLATED SURFACE MOUNT HIGH EFFICIENCY CENTER-TAP RECTIFIER Hermetic Surface Mount Package 12 Amp, 50V to 600V, 35 to 75 nsec FEATURES * * * * * * * * Hermetic Surface Mount Package Very Low Forward Voltage Very Fast Recovery Time Low Thermal Resistance Isolated Package High Surge Center-Tap Configuration Available Screened To MIL-S-19500, TX, TXV and S Levels 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.
