| 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 SRAF0830 thru SRAF0860 SCHOTTKY BARRIER RECTIFIERS 8 AMPERES 30-60 VOLTS ITO-220AC MAXIMUM RATINGS Characteristic Peak Repetitive Reverse Voltage Working Peak Reverse Voltage DC Blocking Voltage RMS Reverse Voltage Average Rectifier Forward Current 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 30 VRRM VRWM VR VR(RMS) IF(AV) 30 35 35 SRAF08 40 40 45 45 50 50 60 60 V Unit 21 25 28 8 32 35 42 V DIM A IFM 16 A IFSM 150 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 =8 Amp TC = 25J ) ( IF =8 Amp TC = 125J ) Maximum Instantaneous Reverse Current ( Rated DC Voltage, TC = 25J ) ( Rated DC Voltage, TC = 125J ) Symbol 30 VF 35 SRAF08 40 45 50 60 V Unit 0.55 0.48 0.65 0.57 IR 1.0 30 mA SRAF0830 thru SRAF0860 FIG-1 FORWARD CURRENT DERATING CURVE AVERAGE FORWARD RECTIFIED CURRENT (Amp.)
