Microsemi's New Transient Voltage Suppression Diodes Protect Aircraft Electrical Systems from Damage Caused by Dangerous Lightning Strikes

6.5kW and 7.5kW Solutions Also Ideal for Other Demanding Aviation, Military, Automotive and Industrial Applications

ALISO VIEJO, Calif., Aug. 13, 2013 — (PRNewswire) — Microsemi Corporation (Nasdaq: MSCC), a leading provider of semiconductor solutions differentiated by power, security, reliability and performance, today announced two new plastic large area device (PLAD) transient voltage suppression (TVS) diode products that protect aircraft electrical systems from damaging transient lightning strikes. The new 6.5kW and 7.5kW devices are the latest addition to Microsemi's innovative PLAD TVS product portfolio and feature 50 percent smaller footprints than the company's current 15kW and 30kW solutions. The new TVS diodes are offered in voltages ranging from 10 volts (V) to 48V and comply with industry-standard RTCA DO-160 requirements for lightning protection in aircrafts.  

Unique features include Microsemi's patented, low-profile PLAD surface mount package, which allows product developers to reduce board space and overall component weight. The highly-integrated, single-component diodes are also more reliable than alternative multiple-device solutions, making them ideal for demanding aviation, military, automotive and industrial applications.

"The trend towards aircraft electrification, greater reliability and higher fuel efficiency is on the rise, which is driving the need for increasingly robust, lighter and smaller TVS solutions that provide superior protection against transient over-voltage occurrences," said Durga Peddireddy, director of marketing and applications for Microsemi's High Reliability Group. "As a leader in high-reliability solutions, Microsemi continues to execute on a full range of innovative product developments to support the stringent and evolving needs of this industry."

Microsemi's TVS diodes provide aircraft electrical systems with critical protection by going into avalanche breakdown within no more than a few nanoseconds after a strike, clamping the transient voltage and routing its current to the ground.

Microsemi: Leadership in TVS Devices
Microsemi offers the industry's broadest portfolio of TVS devices. Between 2,000 and 5,000 Microsemi TVS devices have been deployed, per plane, across all major commercial airframes that are currently in use worldwide throughout the industry. The company's TVS products are currently used in multiple engine control units and actuator controls, as well as a variety of power distribution, environmental control, communications and instrumentation systems.

Microsemi's proprietary PLAD package offers rugged construction with no wire bonds and high surge capabilities. An exposed pad on the bottom of the diode enables excellent thermal resistance. Moisture Classification is Level 1 with no dry pack required per IPC/JEDEC J-STD-020.

All of Microsemi's PLAD packaged devices are 100 percent surge tested and can be supplied in various 'screened' versions (M, MA, MXL and MX)  that have been exposed to levels of additional screening tests (similar to those applied to JANTX military grade devices) to improve reliability. Material and manufacturing changes are made only under a process change notification process with the customer.

Additional TVS features include:

  • Available in various screening quality levels and in both uni-directional and bi -directional constructions
  • Voltage: 10V to 48V
  • Finish: e3 and non e3
  • Halogen-free

Availability and Pricing
The 6.5kW and 7.5kW series TVS diodes are available in all screening levels. The price starts at $2.49 in 10,000 unit quantities. For more information, visit http://www.microsemi.com/product-directory/606-discretes or contact Microsemi at Email Contact.

In addition to TVS diodes, Microsemi's aviation product portfolio includes: FPGAs; integrated standard and custom products; integrated circuits; power conditioning and management components and modules; application specific integrated circuits (ASICs); RF and microwave devices and components; high-density memory products; custom semiconductor packaging; and integrated power distribution systems.
