For capacitive load, derate current by 20%. TYPE NUMBER Maximum Recurrent Peak Reverse Voltage Maximum RMS Voltage Maximum DC Blocking Voltage Maximum Average Forward Rectified Current .375"(9.5mm) Lead Length at Ta=55 C
FEATURES
Peak Forward Surge Current, 8.3 ms single half sine-wave superimposed on rated load (JEDEC method) Maximum Instantaneous Forward Voltage at 3.0A Maximum DC Reverse Current Ta=25 C at Rated DC Blocking Voltage Ta=100 C Maximum Reverse Recovery Time (Note 1) Typical Junction Capacitance (Note 2) 3.0 125 5.0 -65 +150 A A A A nS pF NOTES: 1. Reverse Recovery Time test condition: IF=0.5A, IR=1.0A, IRR=0.25A 2. Measured at 1MHz and applied reverse voltage of 4.0V D.C. * Low forward voltage drop * High current capability * High reliability * High surge current capability * Case: Molded plastic * Epoxy: UL 94V-0 rate flame retardant * Lead: Axial leads, solderable per MIL-STD-202, method 208 guranteed * Polarity: Color band denotes cathode end * Mounting position: Any SF31G THRU SF37G * Good for switching mode application VOLTAGE RANGE 50 to 600 Volts CURRENT
