MAXIMUM RATINGS AND ELECTRICAL CHARACTERISTICS Rating 25 C ambient temperature uniess otherwies specified. Single phase half wave, 60Hz, resistive or inductive load. 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
FEATURES
Peak Forward Surge Current, 8.3 ms single half sine-wave superimposed on rated load (JEDEC method) Maximum Instantaneous Forward Voltage per Leg at 10A Maximum DC Reverse Current Ta=25 C at Rated DC Blocking Voltage Ta=100 C Typical Junction Capacitance (Note1) NOTES: 1. Measured at 1MHz and applied reverse voltage of 4.0V D.C. 2. Thermal Resistance Junction to Case. * Low forward voltage drop * High current capability * High reliability * High surge current capability * Epitaxial construction * Case: Molded plastic * Epoxy: UL 94V-0 rate flame retardant * Lead: Lead solderable per MIL-STD-202, method 208 guranteed * Polarity: As Marked * Mounting position: Any
