The 53815 from Modular Devices is a Space Qualified Solid-State Relay with a bias voltage of 4.7-5.3 V and a bias current of 30-50 mA. This relay has a command current of up to 2 mA and a maximum operate pin current of 5 mA. It has a contact resistance of 0.2-0.25 Ohms and a power consumption of up to 2 W. This space-qualified relay has a maximum contact voltage rating of 300 V and a leakage current of 60-100 µA. It has a delay time of 12-40 µS and a dynamic de-energize time of 5-20 µS. The solid-state relay has a radiation tolerance TID of 100 kRads (S and SE Grades) and a SEE LET of less than 82Mevcm2/mg. It incorporates Wide band gap (WBG) semiconductors, such as GaN (Gallium Nitride) and SiC (Silicon Carbide) for improved SSR voltage drop. It has a mass of 18 grams and comes in a rugged hermetic package.
