Type BI
relays conduct load current in both directions.
Type BI+
relays, in a BI configuration, conduct load current in both directions.
Type UNI
relays conduct load current from the positive terminal to the negative terminal only.
Type BI+
relays, in a UNI configuration with output MOSFETs wired in parallel, enable higher load current from a positive terminal to a negative terminal only. The accompanying SSR tables reference these types (BI, BI+, & UNI) for all devices listed.

Features & Benefits
Low drive current High reliability No EMI/RFI generation AC or DC switching Current limiting devices available Fault-protected versions available Low off-state leakage IXYS Integrated Circuits' line of solid state relays is one of the broadest in the industry. The devices use discrete semiconductor components and the patented OptoMOS architecture to deliver fast, reliable, bounce-free switching in a compact design. Semiconductor relays are an ideal replacement for larger reed and electromechanical relays. Compared to these old electromagnetic technologies, our OptoMOS relays offer significantly lower drive current, small package size, no susceptibility to magnetic interaction, and solid state reliability. All of these are key requirements for the design of today's complex, low-power, multi-channel products. Output Configurations
