Clare announces the CPC1130N, CPC1135N and CPC1231N OptoMOS solid-state relays (SSR). These 3 SSRs are optically coupled, normally closed relays, which utilize depletion mode MOSFETs to achieve a 1 Form B relay contact configuration. All are packaged in the miniature 4-pin SOP package. These products are normally closed switches which consume a minimal amount of power in the 'ON' state and feature silent switching. The blocking voltage for all three products is 350 V and the load current handling is 120 mA. The maximum on-resistance for the CPC1130N and CPC1231N is 30 Ω, while the CPC1135N is 35 Ω. All products are packaged in the miniature 4-pin SOP package. With an area of 15.5 square mm and a height of only 2.2 mm, the Clare 4 pin SOP package is the smallest SSR in the Clare portfolio.
