Microchip Low Capacitance TVS

Low Capacitance TVS

Microsemi's Low Capacitance Transient Voltage Suppressors (TVS) are designed in high quality for a wide range of applications including military and medical equipment, telecommunications, computers, and their peripherals. Microsemi also provides protection to the electronics of engine control systems in the sophisticated avionics and aerospace industries. The company offers a broad portfolio of both uni- and bi-directional discreet plastic TVS devices with power levels from 600W to 100kW. The qualification test plans and reliability monitoring provided for all these products are in line with the best industry-standard practices. This catalog includes an exciting expansion in Microsemi’s industry-leading Plastic Large Area Device (PLAD) surface mount package offerings for TVS devices. Plads provide large exposed metal pads on the bottom of the package with an excellent direct internal connection to the die – there are no wire bonds. This provides a very low resistance thermal path, which is much superior to axial leaded devices and is critical in meeting the expanding requirements for multi-stoke and multi-burst event protection in composite body aircraft. Increasing emphasis is being placed on multi-stroke and multi-burst lightning protection, particularly (but not exclusively) in the protection of the growing proportion of new aircraft being built with largely composite bodies. Test standards for these hazards are defined by RTCA standard DO-160. Microsemi’s high-reliability plastic PLAD packaged TVS devices are uniquely suited to address these requirements.
