MOSPEC SR22 thru SR26 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 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. *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 halfware, single phase, 60Hz) Operating and Storage Junction Temperature Range Symbol SR22 SR23 SR24 SR25 SR26 VRRM VRWM VR 20 VR(RMS) 14 30 40 60 V DIM 21 28 IO 35 42 V 2.0 A 50 A -65 to +150 ℃ IFSM TJ , TSTG 50 Unit ELECTRIAL CHARACTERISTICS Characteristic Symbol SR22 SR23 SR24 SR25 SR26 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 10 Maximum Thermal Resistance Junction to Case RθJC 50 Typical Junction Capacitance ( Reverse Voltage of 4 volts & f=1 MHz ) CP 0.55 105 Unit 0.70 V mA o 90 C/W PF 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 CASE--Transfer molded plastic OLARITY--Cathode indicated polarity band SR22 Thru SR26 NSTANTANEOUS FORWARD CURRENT (Amp.)
