This test report covers the neutron fluence tests performed on the
RDHA710SE10A2F Dual Solid-State-Relay in a hermetic package. The neutron
fluence test was performed to determine the effects displacement damage had on
the device performance. On December 21, 2005, International Rectifier
characterized this device for neutron hardness at the University of Massachusetts,
Nuclear Research Facility using their Fast Neutron Irradiator.
SUMMARY OF RESULTS
All of the test samples passed the post radiation test requirements for fluence levels
up to 2E12 n/cm
. The results show degradation in the device’s propagation delay
after exposure to neutron irradiation of 2E12 n/cm
The test method used in the development of the Test Plan was MIL-PRF-883,
method 1017 Neutron Irradiation. This method established the basic requirements
for the performance and execution of the tests.
The samples were exposed to neutron irradiation in an un-biased state with all of the
device leads open in a conductive bag. Post radiation testing of the devices occurred
after the decay of radioactivity of the devices reached an acceptable safe level
determined by the facilities personnel. The rate of decay was dependent on the
amount of exposure to neutrons and the package materials. The devices were
contained in a 20 +/-10C environment to minimize the effects due to annealing. The
devices were tested on December 21, 2005 for post exposure effects.
The Radiation Test Specification is included in Appendix B. The testing occurred in
the following manner:
The purpose of this test is to characterize and establish Neutron effects for International Rectifier’s
hybrid Dual Solid State Relay
The data resulting from the tests may be incorporated in the IR data
sheet for the product.
International Rectifier shall be responsible for conducting the tests, which shall be performed at the
University of Massachusetts Research Reactor facility. International Rectifier shall be responsible for
the final Test Report.
3.1 Nuclear Reactor
The University of Massachusetts Research Reactor shall be used to provide the necessary
Neutron beam and energy. University of Massachusetts Research Reactor (UMRR) shall
provide adequate dosimetry for verification of the neutron beam parameters.
3.2 Test Equipment
The necessary test equipment including interface board, cables, power supplies,
measurement system, etc. shall be provided by International Rectifier.
