| 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 SRF20120C SCHOTTKY BARRIER RECTIFIERS 20 AMPERES 120 VOLTS ITO-220AB 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 VRRM VRWM VR VR(RMS) IF(AV) SRF20120C 120 Unit V 84 10 20 20 V A DIM 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 IFM A IFSM 200 A TJ , TSTG -65 to +125 J 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 VF SRF20120C 0.85 0.68 Unit V Common Cathode Suffix "C" IR 0.5 20 mA SRF20120C FIG-1 FORWARD CURRENT DERATING CURVE AVERAGE FORWARD RECTIFIED CURRENT (Amp.)
