Aliso Viejo, California-based Microsemi Corporation (Nasdaq: MSCC) has announced the availability of two new versions of its transient voltage suppressor (TVS) devices in its patented plastic large area device (PLAD) package, the company said.
The 18-kilowatt (kW) MPLAD18KP and 36-kW MPLAD36KP TVS families meet today´s lightning protection requirements in aircraft, including the multi-strike lightning standard (RTCA DO-160E), which have grown in importance as a result of the introduction and growing use of composite body airframes.
Microsemi´s new products are high power TVS devices in low-profile surface-mount packages with design features to minimize thermal resistance and cumulative heating. Microsemi´s plastic large area device (PLAD) technology enables more effective surface-mount TVS packaging for the MPLAD18KP and MPLAD36KP, as it 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-kW MPLAD18KP and 36-kW MPLAD36KP TVS devices are designed for a variety of applications within the aerospace market, including engine control units, actuator controls, power distribution, power density improvements, environmental controls, communications and instrumental systems.
The two new devices are complementary to Microsemi´s transient voltage suppressor portfolio for avionics that features low capacitance TVS, standard unidirectional and bidirectional TVS (surface mount and through-hole), TVS array and low capacitance TVS array solutions. In addition, the MPLAD18KP and MPLAD36KP lightning and automotive load dump protection allow their utilization in applications serving the automotive and defense markets, as they can provide a wide range of suppression capability for varying threat requirements either in a single or multiple devices.
Microsemi offers a range of high reliability products and solutions for flight critical avionics and power conversion applications addressing the evolving needs of the aviation industry.
Microsemi Corporation offers a comprehensive portfolio of semiconductor and system solutions for aerospace & defense, communications, data center and industrial markets. The company has approximately 4,800 employees globally.
