Sanken RU3A fast recovery rectifier diode 1.5A 600V in a D2A package (D1012). High current capability, High surge current capability, High reliability, Low reverse current, Low forward voltage drop and Fast switching for high efficiency. This diode can replace any of the following diodes 1N4933, 1N4934, 1N4935, 1N4936, 1N4937, RU-2, RU2, RU2A, RU2M, RU2AM, RU1, RM1, RM1A because its rated higher then all listed diodes in the series. These are used on monitor chassis such as K7000 Wells Gardner at D13, D14, D15, D16, D17 and many other monitors and PCB. (1.5 amp 600 volt and this is the highest rated diode in the RU3 series).
