1/7 optical mos relays ocms2 m m m m m 6 series ? electronic components ocms2 m m m m m 6 series general-purpose sop type optical mos relay for ac/dc load general description the ocms2 m 6 series is a family of optical mos relays for ac/dc load. 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 sop type package. the series reduced its area to 50% and its volume to 27% of the conventional dip or smd- type optical mos relays. the series is 2.1mm thick and is ideal for modem card applications. 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 curcuit compatibility because of its non-mechanical operation. optical mos relay switches also dissipate less power than equivalent bipolar devices at lower switching frequencies. features ? extremely low voltage control ? thickness of 2.1mm ? 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 sop package) applications ? telecommunications system (such as modem cards) ? measurement equipment ? home electronics ? automatic meter reading equipment ? other applications requiring small size or high performance ? other applications requiring non-contact switches e2p0052-37-x3 this version: jan. 1998 previous version: may. 1997
