MOSPEC SR37 Thru SR310 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 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 ＊Moisture Sensitivity Level: MSL-1 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 SR37 SR38 VRRM VRWM VR 70 80 VR(RMS) 49 SR39 SR310 90 Unit 100 V DIM 56 63 IO V 3 A 75 A -65 to +150 ℃ IFSM TJ , TSTG 70 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 ELECTRIAL CHARACTERISTICS Characteristic Maximum Instantaneous Forward Voltage (IF =3.0 Amp) Symbol VF Maximum Instantaneous Reverse Current (Rated DC Voltage, TC = 25℃) (Rated DC Voltage, TC = 125℃) IR Maximum Thermal Resistance Junction to Case RθJC Typical Junction Capacitance (Reverse Voltage of 4 volts & f=1 MHz) CP SR37 SR38 SR39 SR310 Unit 0.85 V 0.75 0.01 10 mA o 40 180 150 C/W PF CASE--Transfer molded plastic POLARITY--Cathode indicated polarity band SR37 thru SR310 NSTANTANEOUS FORWARD CURRENT (Amp.)
