Order 1N40___R for stud anode (reverse polarity) types. Ratings and specifications are for frequencies from 50 up to 400 cycles/second, except where noted differently. Non-repetitive voltage and current ratings, as contrasted to repetitive ratings, are ratings which apply for occasional or unpredictable overloads. For example, the forward surge current ratings are non-repetitive ratings that are used in fault co-ordination work. Rating assumes a rectifier diode heat sink dissipation of 2.0C/watt, or less. Rating assumes a rectifier diode heat sink dissipation of 1.0C/watt, or less. Use of a silicone grease (G-E #G623) between the rectifier base and heat sink is recommended. *Indicates JEDEC Registration Parameters. 255 1N4044-56, R INSTANTANEOUS FORWARD CURRENT AMPS. = 425C INSTANTANEOUS FORWARO VOLTAGE - VOLTS 1, MAXIMUM FORWARD CHARACTERISTICS AVERAGE FORWARD POWER DISSIPATION - WATTS 200 400 600 800 1000 AVERAGE FORWARD CURRENT - AMPERES VS.
