Avago Technologies has expanded its solid-state relay family of opto-isolation products. With input drive as low as 2mA and fast switching speeds of less than 0.5ms, Avago's new ASSR-301C/302C and ASSR-401C/402C are designed for sensing and multiplexing applications, such as test and measurement and data acquisition systems, where low power consumption and high system throughput are essential.

The new solid-state relays provide low off-state capacitance of less than 15pF for good signal isolation and low on-resistance for less insertion loss. Additionally, low off-state leakage of less than 10nA reduces system measurement errors. Avago's expanded ASSR series feature qualified performance across a wide range of temperature range of –40 to +85°C, high transient immunity greater than 1kV/s, and an industry high of 3.75kV in insulation protection in a miniature SO-4 package.

Solid-state relay provides several advantages over mechanical relays in switching applications. Avago's SSRs offer lower power consumption and are designed to deliver faster speeds and superior insulation protection in equipment. With no moving parts and smaller form factor, the new SSRs are smaller and more reliable than the mechanical alternatives.
