SKKD 26/12 is a semikron diode rectifier module part number. It is designed to be used in PWM applications, such as AC to DC conversion, in order to provide a regulated DC power output from a variable AC input. It features a rectifying bridge with a nominal voltage of 1600 V, current rating of 12 A, and thermal resistance of 36°C/W. It is also capable of reverse current protection, transient protection and overvoltage protection, helping to provide a safe and reliable power supply.
