MER increases product reliability

The PVY117 series of microelectronic relays (MERs) from International Rectifier (IR) promises to increase product reliability by replacing electromechanical and reed relays that have fragile moving parts and metallic contacts with more reliable, solid-state relays that have no moving parts.

"The new MERs are designed to increase end-product reliability and operational life, since the solid-state construction eliminates contacts that wear out," commented Andy Serkuczewski, Director of Product Management for IR's Microelectronic Relays. "In addition, the PVY117 is housed in a subminiature, surface-mountable package for high-density applications."

Members of the PVY117 series feature bounce-free operation. Their low on-state contact resistance and low off-state capacitance maximize performance in low voltage and high test frequency semiconductor automated test equipment (ATE) and other instrumentation circuits. The company added that MERs are much smaller compared to the electromechanical relays they are designed to replace.

The PVY117 and PVY17-T MERs feature an off-state blocking of 40V, on-state resistance of 0.95? (max), off-state capacitance of 14.5pF (max), and off-state leakage of 1nA (max). Housed in SOP4 (PVY117) and SOP4+T&R (PVY117-T) packaging options, they are priced at $2.75 and $2.80, respectively, for 10,000-unit quantities. Prices are subject to change.
