Carrollton, Texas Providing design engineers with a range of isolators for applications which require 6 kVdc electrical isolation, TT electronics OPTEK Technology has expanded their family of optically coupled isolators. Designated the OPI7000 Series, the isolators consist of an infrared light emitting diode coupled to an NPN silicon phototransistor or photodarlington transistor. The isolators are suitable for applications that require high-voltage isolation between input and output, as well as electrical isolation in dirty environments, including industrial, medical and office equipment.
The isolators feature an input-to-output isolation voltage of ±6 kV and a power dissipation rating of 100 mW. LED peak wavelength is 890 nm for the OPI7002 and OPI7010 devices and 890 nm or 935 nm for the OPI7320 and OPI7340 isolators. The OPI7002 and OPI7010 versions feature a current transfer ratio (CTR) of 20% and 100%, respectively, while the OPI7320 and OPI7340 versions with a photodarlington sensor feature CTRs of 200% and 400%, respectively. Operating temperature range is -40°C to 85°C.
The LED and sensor are enclosed in a high-dielectric plastic housing, and the 0.30 inch pin spacing is compatible with standard dual-in-line packages. OPTEK will also produce devices to meet specific customer requirements. Custom electrical specifications including wire, cabling and connectors are also available.
