OM5301ST/RT/DT OM5303ST/RT/DT OM5302ST/RT/DT OM5304ST/RT/DT 20 AMP ULTRA FAST, ULTRA LOW FORWARD VOLTAGE CENTER-TAP POWER RECTIFIER 20 Amp, 50 To 200 Volts, 35 ns trr FEATURES • • • • • • • Small Size/JEDEC TO-257AA Outline Very Low Forward Voltage Very Fast Switching Time Hermetic And Isolated Metal Package Available As Common Cathode Or Common Anode Low Thermal Resistance 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. 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.
