3 GGeenneerraallDDeessccrriippttiioonnAdva nced high performance semiconductor devices can be sensitive to Single Event Latch-Up (SEL) effectwhen exposed under radiation in the space environment. Even if SEL is a very rare event, it can lead to devicedestruction. A safe design for a mission critical application shall include a protection device called the Latch-Upcurrent Limiter (LCL).The 3 DPM0168-2 LCL monitors the power supply line of the radiation sensitive device and switches it offinstantaneously in case of radiation induced SEL .Featuring specific radiation effect mitigation techniques and utilizing space design derating rules, the Rad Hardby design 3 DPM0168-2 LCL is an ITAR Free product and features a SEL/SET LETth of 80 and aTID of 50krad (Si).
