Proton-Electrotex engineers developed freewheeling diodes to operate at the reverse recovery process with high change rate of reverse recovery current (dI_rrm/dt), and high power supply reverse voltage (V_R) by means of proton irradiation technology, sintering technology and implementation of
n’-buffer. The diodes are designed to be used as reverse diodes for high voltage stacks assembled using IGBT and IGCT.
