1/7 optical mos relays ocm2 m m m m m 4, 2 m m m m m 5 series ? electronic components ocm2 m m m m m 4, 2 m m m m m 5 series low output-capacitance type optical mos relay for ac/dc load general description the ocm2 m 4 and ocm2 m 5 series are optical mos relays for ac/dc load that provide high- speed response and are capable of handling high-frequency signals. the input portion is an infrared light emitting diode. the output portion uses a combination of low-capacitance vd- mos (vertical diffusion mos) fets and photodiode arrays. the device is encased in an extremely small 6-pin plastic dip or smd-type (gull-wing) package. the optical mos relay switch may be used in applications that currently use mechanical relay switches, but offers smaller size, noise-free switching, and electronic circuit compatibility because of its non-mechanical operation. optical mos relay switches also dissipate less power than equivalent bipolar devices at lower switching frequencies. features ? infinitesimally small control voltage ? excellent high-frequency characteristics (>30 db isolation at 10 mhz) ? high-speed switching response of 200 m s or less ? low leakage current ? no chattering or switch bounces ? no mechanical switching noises ? small size and easy mounting (6-pin plastic dip or smd-type[gull-wing] package) applications ? measurement equipment ? audio-visual equipment ? home electronics ? automatic meter reading equipment ? other applications requiring small size or high performance ? other applications requiring non-contact switches e2p0049-37-x3 this version: jan. 1998 previous version: may. 1997
