1/7 optical mos relays ocm1 m m m m m 2, 1 m m m m m 3 series ? electronic components ocm1 m m m m m 2, 1 m m m m m 3 series low on-resistance type optical mos relay for dc load only general description the ocm1 m 2 and ocm1 m 3 series are optical mos relays for dc load only. the input portion is an infrared light emitting diode. the output portion uses a combination of 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 ? high reliability due to non-contact and optical operation ? 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 ? telecommunications equipment ? measurement equipment ? home electronics ? automatic meter reading equipment ? other applications requiring small size or high performance ? other applications requiring non-contact switches e2p0045-37-x3 this version: jan. 1998 previous version: may. 1997
