EEWeb Whiteboard - OMRON's New VSON Packaged MOSFET Relays.

MOSFET relays are a solid-state replacement for the commonly used reed relays. These solid state relays are have many benefits over reed relays, largely in their vastly superior longevity.

VSON stands for Very Small Outline Non-Leaded, an SMT package measuring a mere 2.45 by 1.45 by 1.3 millimeters. This offers a 50% decrease in bottom surface area compared to USOP packaging, while the land contacts are designed to improve solderability. Despite the incredibly small size, there are models available for 20 volts, stepping all the way up to 100 volts.
