MOSPEC SR27 Thru SR210 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. 2.0 AMPERES 70-100 VOLTS ＊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 DO-214AA(SMB) ＊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 Non-Repetitive Peak Surge Current (Surge applied at rate load conditions half-wave, single phase,60Hz ) Operating and Storage Junction Temperature Range Symbol SR27 SR28 SR29 SR210 Unit VRRM VRWM VR 70 80 90 100 V VR(RMS) 49 56 63 70 V IO 2.0 A 50 A -65 to +150 ℃ IFSM TJ , TSTG ELECTRIAL CHARACTERISTICS Characteristic Symbol SR27 SR28 SR29 Maximum Instantaneous Forward Voltage (IF =2.0 Amp) VF Maximum Instantaneous Reverse Current (Rated DC Voltage, TC = 25℃) (Rated DC Voltage, TC = 125℃) IR 0.5 20 Maximum Thermal Resistance Junction to Case RθJC 50 Typical Junction Capacitance (Reverse Voltage of 4 volts & f=1 MHz) CP 0.75 80 SR210 A B C D E F G H MILLIMETERS MIN MAX 3.30 3.90 4.20 4.60 1.80 2.20 5.10 5.60 1.90 2.50 1.30 0.22 0.95 1.35 Unit V 0.85 mA o 75 DIM C/W pF CASE--Transfer molded plastic POLARITY--Cathode indicated polarity band SR27 Thru SR210 NSTANTANEOUS FORWARD CURRENT (Amp.)
