VO1401AEFTR/VOR1003M4T Solid-State Relays

The Vishay VO1401AEFTR and VOR1003M4T industrial-grade 1 Form A solid-state relays come in a surface-mount SOP-4 package and combine a high continuous load current of 550 mA and 5 A, respectively, with load voltages of 60 V and 30 V, an isolation voltage of 3,750 V_RMS, and a low leakage current of less than 1 µA typical. With their high current capability, the devices are ideal for replacing electromechanical relays (which are susceptible to damaging vibrations) with contactless optical relays that provide robust, vibration-proof switching for higher reliability and a longer service life. In addition, the high isolation voltage of the VO1401AEFTR and VOR1003M4T allows them to be used in harsh environments. The compact package of the relay saves board space, while the low leakage current translates into higher efficiency by helping to keep the sensitive load on the output side turned off.
