The 53805 from Modular Devices is a Space Qualified Solid-State Relay with a contact voltage rating of 600-1000 V and a contact current rating of 10-15 A. This relay requires a bias voltage of 4.75-5.25 V and a bias current of 30-50 mA. It has a contact resistance of up to 0.4 Ohms and has a power dissipation of 30 W. The relay has an energize time of 10-30 µS and a dynamic de-energize time of 5-20 µS. It has a radiation tolerance TID of 100 kRads (S and SE Grades) and a SEE LET of less than 82 Mevcm2/mg. This space-qualified relay incorporates a Wide band gap (WBG) semiconductor for low resistance and features a selectable continuous or Mag latch function. It has a mass of 32 g and is packaged in a rugged hermetically sealed case which can withstand severe environments.
