patented OptoMOS architecture, are controlled by a
highly efficient infrared LED. The combination of low
on-resistance and high load current handling
capability makes this relay suitable for a variety of high
performance switching applications.

The unique i4-PAC package pioneered by IXYS
enables Solid State Relays to achieve the highest load
current and power ratings. This package features a
unique IXYS process where the silicon chips are soft
soldered onto the Direct Copper Bond (DCB)
