For many years, IR has been the leader in radiation hardened MOSFETs. The design and processing of these devices has been carefully planned and implemented to result in a superior product. The thorough hardness assurance testing imposed on our product is an important component of this product line which has been overlooked by many in the industry. The philosophy behind the hardness assurance testing is based on the military requirements outlined in MIL-PRF-19500 and its associated detail slash sheets. IR has elected to exceed the military requirement and is currently using sampling plans as much as 2 times greater than is required.
