Technical content
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. ＊Low Forward Voltage. ＊Low Switching noise. ＊High Current Capacity ＊Guarantee Reverse Avalanche. ＊Guard-Ring for Stress Protection. ＊Low Power Loss & High efficiency. ＊150℃ Operating Junction Temperature ＊Low Stored Charge Majority Carrier Conduction. ＊Plastic Material used Carries Underwriters Laboratory Flammability Classification 94V-O ＊In compliance with EU RoHs 2002/95/EC directives MAXIMUM RATINGS Characteristic Symbol SK27 SK28 SK29 SK210 Unit Peak Repetitive Reverse Voltage Working Peak Reverse Voltage DC Blocking Voltage VRRM VRWM VR 70 80 90 100 V RMS Reverse Voltage VR(RMS) 49 56 63 70 V Average Rectifier Forward Current IO 2.0 A Non-Repetitive Peak Surge Current (Surge applied at rate load conditions half-wave, single phase,60Hz ) IFSM 50 A Operating and Storage Junction Temperature Range TJ , TSTG -65 to +150 ℃ ELECTRIAL CHARACTERISTICS Characteristic Symbol SK27 SK28 SK29 SK210 Unit Maximum Instantaneous Forward Voltage (IF =2.0 Amp) VF 0.75 0.85 V Maximum Instantaneous Reverse Current (Rated DC Voltage, TC = 25℃) (Rated DC Voltage, TC = 125℃) IR 0.5 mA Maximum Thermal Resistance Junction to Case RθJC 50 oC/W Typical Junction Capacitance (Reverse Voltage of 4 volts & f=1 MHz) CP 80 75 pF SCHOTTKY BA RRIER RECTIFIERS
