The RHRP8120 from onsemi is a high-voltage hyperfast recovery rectifier diode featuring soft-recovery characteristics and a silicon-nitride-passivated, ion-implanted epitaxial planar structure. Its repetitive peak reverse voltage, working peak reverse voltage, and DC blocking voltage are all rated at 1200V, with an average rectified forward-current rating of 8A.
At a forward current of 8A and a current commutation rate of 200A/μs, the device provides a maximum reverse-recovery time of 70ns. At a 1A forward current, the maximum recovery time is 55ns. Its low stored charge and soft-recovery behavior help reduce ringing, electrical noise, and switching losses in power-conversion circuits.
The RHRP8120 supports an average forward current of 8A at a 140°C case temperature, a repetitive peak surge current of 16A, and a non-repetitive surge current of 100A. Maximum forward voltage is 3.2V at 8A and 25°C, while maximum power dissipation is 75W.
The device is avalanche-energy rated at 20mJ and supports an operating and storage junction-temperature range from −65°C to +175°C. Maximum junction-to-case thermal resistance is 2°C/W, typical reverse-recovery charge is 165nC, and typical junction capacitance is 25pF.
The component is supplied in a two-lead TO-220AC through-hole package, with the metal mounting flange electrically connected to the cathode. It is intended for switching power supplies, freewheeling circuits, clamping circuits, and other high-voltage power-switching applications.
