The RDHA720SF06A1NP is a 60V 20A rad hard solid state relay with a single-pole-single-throw (SPST) normally open configuration in a 8-pin surface mount package. It has standard packaging, is characterized for 100 krad(Si) total ionizing dose and utilizes IR HiRel's R5 MOSFET technology for its input and output MOSFETs. This device is the unscreened version of RDHA720SF06A1NK.
