Additional Details

The LTV-4N35S-TA-AD optocoupler consists of an infrared emitting diode (IRED) optically coupled to a silicon NPN phototransistor. It is housed in a DIP-4 package. Key specifications include a collector-emitter breakdown voltage typically around 70V and isolation voltage of 5 kVrms. The current transfer ratio (CTR) varies depending on the specific part number, and should be consulted in the datasheet for your specific design requirements. It is commonly used to isolate control signals from power circuits or noisy environments. Proper external components (resistors) are needed to set the current limiting and pull-up functions. This device offers excellent performance and reliability for various isolation applications.
