OptocouplerSMD, SOP and SSOP Packages OPIA400 through OPIA414 Features: 2,500 to 5,000 Vrms electrical isolation Choice of a Single and Dual LED Phototransistor or Photo Darlington Sensor Low-cost plastic Dual-In-Line (DIP) package Agency Approvals: UL Certification No: E58730 VDE pending Description: The OPIA series optocouplers are designed for applications that use an analog output (Phototransistor or Photodarlington) in a surface mount package. A wide selection of configurations are available. With typical isolation voltage of 2,500 or 5,000 Volts RMS, these products meet typical power system isolation requirements. Theory of operation: The LED transmitter is used to illuminate the Photosensor providing electrical isolation between two power systems while maintaining the ability to transmit information from one power system to the other. In many applications, analog signal levels may be required to be transmitted between two power systems while maintaining isolation between the power systems up to 5,000 volts RMS. A variety of LED and photosensor configurations are available depending on the system requirements. The ratio Current Transfer Ratio (CTR) is identified between the output current and input current for analog photosensors. CTR ratios can range from as low as 5 to over 9,000 depending on the device. Photosensor Current 20mA CTR = = *100 = 200 LED Current 10mA All SMD products are shipped in a shipping tube with TR identified on the end of the part number. Example: OPI400ATR is a 4-Pin SMD shipped in tape and reel (TR) Applications: High voltage isolation, up to 5,000 Volts RMS PCBoard power system isolation Industrial equipment power isolation Medical equipment power isolation Office equipment OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.
