OM5257SA/RA/DA OM5259SA/RA/DA OM5258SA/RA/DA OM5260SA/RA/DA HERMETIC JEDEC TO-254AA HIGH EFFICIENCY, CENTER-TAP RECTIFIER 40 Amp, 50 To 200 Volts, 50 ns trr FEATURES • • • • • • • • Very Low Forward Voltage Very Fast Switching Time Hermetic Metal Package, JEDEC TO-254AA Outline Low Thermal Resistance Isolated Package High Surge Ceramic Feedthroughs Available Available Screened To MIL-S-19500, TX, TXV And S Levels 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.
