| MOSPEC Switchmode Full Plastic Dual Schottky Barrier Power Rectifiers Using the Schottky Barrier principle with a Molybdenum barrier metal. These state-of-the-art geometry features epitaxial construction with oxide passivation and metal overlay contact. Ideally suited for low voltage, high frequency rectification, or as free wheeling and polarity protection diodes. * Low Forward Voltage. * Low Switching noise. * High Current Capacity * Guarantee Reverse Avalanche. * Guard-Ring for Stress Protection. * Low Power Loss & High efficiency. * 125J Operating Junction Temperature * Low Stored Charge Majority Carrier Conduction. * Plastic Material used Carries Underwriters Laboratory SRF2070 Thru SRF20100 SCHOTTKY BARRIER RECTIFIERS 20 AMPERES 70-100 VOLTS ITO-220 MAXIMUM RATINGS Characteristic Peak Repetitive Reverse Voltage Working Peak Reverse Voltage DC Blocking Voltage RMS Reverse Voltage Average Rectifier Forward Current Total Device (Rated VR),TC=100J Peak Repetitive Forward Current (Rate VR, Square Wave, 20kHz) Non-Repetitive Peak Surge Current (Surge applied at rate load conditions halfware, single phase, 60Hz) Operating and Storage Junction Temperature Range Symbol 70 VRRM VRWM VR VR(RMS) IF(AV) 70 80 80 SRF20 90 90 100 100 V Unit 49 56 10 20 20 63 70 V DIM A IFM A IFSM 200 A TJ , TSTG -65 to +125 J A B C D E F G H I J K L M N P O Q MILLIMETERS MIN MAX 15.05 15.15 13.35 13.45 10.00 10.10 6.55 6.65 2.65 2.75 1.55 1.65 1.15 1.25 0.55 0.65 2.50 2.60 3.00 3.20 1.10 1.20 0.55 0.65 4.40 4.60 1.15 1.25 2.65 2.75 3.35 3.45 3.15 3.25 ELECTRIAL CHARACTERISTICS Characteristic Maximum Instantaneous Forward Voltage ( IF =10 Amp TC = 25J ) ( IF =10 Amp TC = 125J ) Maximum Instantaneous Reverse Current ( Rated DC Voltage, TC = 25J ) ( Rated DC Voltage, TC = 125J ) Symbol 70 VF 0.75 0.68 80 SRF20 90 0.80 0.70 100 Common Anode Suffix " A " Unit Common Cathode Suffix " C " V Double Suffix " D " IR 1.0 30 mA SRF2070 Thru SRF20100 FIG-1 FORWARD CURRENT DERATING CURVE AVERAGE FORWARD RECTIFIED CURRENT (Amp.)
