LX7710 Octal 125V, 700mA Redundant Diode Pairs for Space Description The LX7710 is a diode array that features high breakdown voltage diodes with ESD protection and built-in redundancy that is radiation-hardened by design. It is typically used as a companion device to the AAHS298B source driver to build redundant power switches. The array contains 8 series connected diode pairs, and is intended for power ORing applications and for redundant diode clamps for inductive loads. The series connected diodes are redundant should one of the diodes fail in a short circuit. Individual diodes within the array have a 125V maximum reverse voltage rating, and can each handle 700mA continuous current, which is 5.6A per package. ESD protection is also included; the two series ESD zener diodes have a working voltage of 100V each for a total of 200V. The LX7710 is packaged in a 20 pin ceramic hermetic CSOIC package and is QML-V and QMLQ certified. It operates over a -55°C to 125°C temperature range, and is radiation tolerant to a minimum of 100krad(Si) TID, as well as single event effects. Features • 125V minimum breakdown voltage, even if one diode in any string fails for redundancy • 700mA current capability per diode • Low leakage current • ESD protected • Radiation tolerant: 100krad(Si) TID, inherent latchup immunity due to no power pin Applications • Power ORing • Redundant Power Sourcing • Redundant Inductive Load Clamps • Aerospace Satellite Manufacturers • Military Power Electronics .
