Radiation-Tolerant Diode Array IC for Space Satellites Released

21 April 2016

Microsemi Corp. has introduced an integrated radiation-tolerant diode array designed specifically for satellites and other space applications.

The LX7710 features built-in redundancy in the form of eight series-connected diode pairs; should one of the diodes fail in a short-circuit event, it will continue to function in the harsh space environment. The individual diodes in the array have 125V of working voltage, can handle up to 700mA of continuous current, and are electrostatic discharge (ESD) protected.

Microsemi also has announced that its AAHS298B source driver has achieved Qualified Manufacturers List (QML) Class V and QML Class Q from the Defense Logistics Agency Land and Maritime. The source driver can be used in conjunction with the LX7710 device and other radiation-hardened and radiation-tolerant programmable logic products from Microsemi for power management solutions.

Microsemi says the combination of these devices will provide space engineers the ability to meet the demands of providing space applications that are smaller and lighter, which can result in launch cost savings. The integrated products also increases reliability by eliminating the need for separate discrete components in systems. Microsemi says the products have already been used in satellite programs such as the JointPolar Satellite System and NASA’s Orion.

Both devices are available now.
