    Printed circuit board equipped with MOSFET power transistors

    The printed circuit board equipped with MOSFET power transistors (metal-oxide semiconductor field effect transistors) shown at the ILA is a component of the mobile asteroid surface scout. This is part of a small lander package on board of the Japanese craft Hayabusa II, which is scheduled to take off for the asteroid 1993 JU3 at end of 2014.

DLR has successfully qualified power transistors made in Germany for use in space. A particularly critical item was optimising their resistance to cosmic radiation and its disruptive effects. Until now, these components had to be procured from the USA at some expense. This will be changed in the near future by the DLR quality and product assurance department in collaboration with the chip manufacturer Infineon.
