ALISO VIEJO, Calif., 4 Nov. 2012. Microsemi Corp. in Aliso Viejo, Calif., is introducing two transient voltage suppressors (TVS) devices to protect aircraft from the effects of lightning strikes.

The 15 kilowatt MPLAD15KP and 30-kilowatt MPLAD30KP TVS families meet lightning-protection requirements in aircraft, including the multi-stroke standard (RTCA DO-160E). The devices come in the Microsemi plastic large area device (PLAD) package.

The 15-kilowatt and 30-kilowatt PLAD designs help prevent the disruption of digital signal processing, component damage and interruption of function due to inductive load dumps, or the indirect effects of lightning.

The PLAD package combines a large die size with a large exposed bottom-side metal slug for heat sinking. The PLADs are also compatible with standard surface mount assembly automation.

The 15-kilowatt family operates at (standoff) ranges from 7 to 200 volts, and the 30-kilowatt family comes in voltages from 14 400 volts. Unidirectional and bi-directional versions are available. The parts can be supplied in RoHS-compliant form (2002/95/EC) or with tin-lead plating. They are halogen free (IEC 61249-2-21) and meet MSL level 1 (J-STD-020) industry standards.
