Additional Details

The SFH610A-3X007 optocoupler is commonly used to isolate low voltage control circuits from high voltage power circuits. The current transfer ratio (CTR) is an important parameter to consider when selecting an optocoupler. The CTR is the ratio of the collector current to the forward current. This device offers a CTR in 4 groups, allowing selection of the optimal device for specific applications. The isolation voltage rating indicates the maximum voltage that the optocoupler can withstand between the input and output. The SFH610A-3X007 has a high isolation voltage of 5300 VRMS, making it suitable for use in safety-critical applications. The operating temperature range is typically -55°C to +100°C. The package is a standard DIP-4 through-hole package.
