The RDHA720SF06A1NK is a radiation hardened
solid-state relay in a hermetic package. It is configured
as a single-pole-single-throw (SPST) normally open
relay. This device is characterized for 100 krad(Si)
total ionizing dose. The RDHA720SF06A1NK is
optically coupled and actuated by an input current.

Notes for Maximum Ratings and Electrical Characteristic Tables
Specification is guaranteed by design
Optically coupled Solid State Relays (SSRs) have relatively slow turn on and turn off times. Care must be taken to
insure that transient currents do not cause violation of SOA. If transient conditions are present, IR recommends a
complete simulation to be performed by the end user to insure compliance with SOA requirements as specified in
the IRHN7054 data sheet
While the SSR design meets the design requirements specified in MIL-PRF-38534, the end user is responsible for
product derating, as required for the application

Radiation Performance
International Rectifier Radiation Hardened SSRs are tested to verify their hardness capability. The hardness
assurance program at IR uses a Cobalt-60 (
60
Co) Source and heavy ion irradiation. Both pre- and post-
irradiation performance are tested and specified using the same drive circuitry and test conditions to provide
a direct comparison.
