MOSPEC SK32 thru SK36 Surface Mount Schottky Barrier rectifiers SCHOTTKY BARRIER RECTIFIERS Using the Schottky Barrier principle with a Molybdenum barrier meta. 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, in surface mount applications where compact size and weight are critical to the system. 3.0 AMPERES 20-60 VOLTS Features ＊Low Forward Voltage. ＊Low Switching noise. ＊High Current Capacity ＊Guarantee Reverse Avalanche. ＊Guard-Ring for Stress Protection. ＊Low Power Loss & High efficiency. ＊125℃ Operating Junction Temperature ＊Low Stored Charge Majority Carrier Conduction. ＊Plastic Material used Carries Underwriters Laboratory Flammability Classification 94V-O DO-214AC(SMA) ＊In compliance with EU RoHs 2002/95/EC directives MAXIMUM RATINGS Characteristic Peak Repetitive Reverse Voltage Working Peak Reverse Voltage DC Blocking Voltage RMS Reverse Voltage Average Rectifier Forward Current Symbol SK32 SK33 SK34 SK35 SK36 Unit VRRM VRWM VR 20 30 40 50 60 V VR(RMS) 14 21 28 35 42 V 3.0 A 70 A TJ , TSTG -65 to +125 ℃ Characteristic Symbol SK32 SK33 SK34 SK35 SK36 Unit Maximum Instantaneous Forward Voltage ( IF =3 Amp ) VF Maximum Instantaneous Reverse Current ( Rated DC Voltage, TC = 25℃ ) ( Rated DC Voltage, TC = 125℃ ) IR Non-Repetitive Peak Surge Current (Surge applied at rate load conditions halfware, single phase, 60Hz) Operating and Storage Junction Temperature Range IO IFSM ELECTRIAL CHARACTERISTICS Maxmum Thermal Resistance Junction to Lead (Note.1) Maxmum Thermal Resistance Junction to Ambient Typical Junction Capacitance ( Reverse Voltage of 4 volts & f=1 MHz ) Note: 1.
