IXYS Solid State Relay, 120 mA rms/mA dc Load, Surface Mount

These single pole miniature solid state relays have normally closed (1-Form-B) contacts and feature a 4-pin SOP package. They are able to provide 1500 Vrms of input to output isolation by taking advantage of optically coupled MOSFET technology.

The outputs have been constructed from efficient MOSFET switches and photovoltaic die and the well-known OptoMos architecture. The input is an efficient infrared LED which provides the optically coupled control.

By using a double-moulded vertical construction package, they are able to be one of the smallest relays available. This helps to provide a board space saving of at least 20% over other larger 4-pin SOP relays.
