Description

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 90.5 MeV·cm2/mg. Their combination of low RDS(on) and improved SOA allows

for better performance in applications such as Latching Current Limiters (LCL), Solid-State Power Controllers

(SSPC) or DC-DC converters. These devices retain all of the well-established advantages of MOSFETs such as

voltage control, fast switching and temperature stability of electrical parameters.
