ALISO VIEJO, Calif. – Microsemi Corp. in Aliso Viejo, Calif., is introducing the 18-kilowatt MPLAD18KP and 36-kilowatt MPLAD36KP TVS families of transient voltage suppressor (TVS) devices for demanding lightning protection requirements in aircraft.
The TVS devices come in plastic large area device (PLAD) packages, and meet the RTCA DO-160E multi-strike lightning standard, which has grown in importance with the growing use of composite body airframes.
Microsemi's high power TVS devices come in low-profile surface-mount packages with design has to minimize thermal resistance and cumulative heating. Microsemi's PLAD technology combines a large die size with an exposed bottom contact for heat sinking that improves power handling as compared to through-hole devices.
In addition, the devices provide the capability of a bond wire-free part in high vibration environments, supporting high reliability in harsh conditions.
The 18-kilowatt MPLAD18KP and 36-kilowatt MPLAD36KP TVS devices are for engine control units, actuator controls, power distribution, power density improvements, environmental controls, communications, and instrumental systems.
In addition, the MPLAD18KP and MPLAD36KP lightning and automotive load dump protection allow their use in applications serving the automotive and defense markets, as they can provide a wide range of suppression capability for varying threat requirements either in one or several devices.
Microsemi's 18-kilowatt MPLAD18KP and 36-kilowatt MPLAD36KP TVS families are available now. More information is online at www.microsemi.com.
