3D PLUS has more than 200,000 microelectronics components in space, and more than 20 years of flight heritage with no reported failure. Our Flight Heritage is expanding continuously with products launched in Space every month in LEO, MEO and GEO orbits, for deep space exploration missions, for satellite constellation fleets, and for governmental missions in Europe, America, and Asia. Our Flagship missions include Mars 2020, Mars Science Laboratory, Rosetta, New Horizons, Juno, OneWeb, AlphaSat, Sentinel, Ariane 5, ISS, Parker Solar Probe, Insight, and many more.
Advanced high performance semiconductor devices can be sensitive to Single Event Latch-Up (SEL) effect when exposed under radiation in the Space environment. Even if SEL is a very rare event, it can lead to a self destruction of the device and shall be mitigated to ensure the relevant reliability and life time of the application. Therefore, a safe design for a mission critical Space application shall include a protection device.
The 3DPM0168 Latch-Up Current Limiter (LCL) monitors the power supply line of the semiconductor device and switches it off instantaneously in case of any overcurrent or “radiation induced SEL” in order to protect the device from overheating.
Featuring specific radiation effect mitigation techniques and utilizing Space design derating rules, the Rad-Hard-by-Design 3DPM0168 LCL is an ITAR Free product and features a SEL/SEE LETth of 80 MeV-cm²/mg and a TID of 50 krad(Si).
The 3DPM0168 is manufactured with 3D PLUS Space Qualified stacking technology designed for for high reliability applications, and is available in a compact size and low weight 20-pin SOP package.
Overcurrent protection for power lines from 0.8V to 6V and up to 2A
Very fast switch-off time (10µs max)
