International Rectifier – Radiation Hardened Power MOSFET Thru-Hole (Low-Ohmic TO-257AA) 60V, 30A, P-channel, R9 Superjunction Technology (04/2022)
IR HiRel R9 technology provides superior power MOSFETs for space applications. This family of p-channel MOSFETs are the first radiation hardened devices that are based on a superjunction technology. These devices have improved immunity to Single Event Effect (SEE) and have been characterized for useful performance with Linear Energy Transfer (LET) up to 91.3 MeV·cm2 /mg. Their combination of low RDS(on) and improved SOA allows for better performance in applications such as Latching Current Limiters (LCL) or Solid-State Power Controllers (SSPC). These devices retain all of the well-established advantages of MOSFETs such as voltage control, fast switching and temperature stability of electrical parameters
