Additional Details

The LTV-3052 is typically offered in an SO package. Key electrical specifications include a high isolation voltage (often exceeding 5kVrms), a current transfer ratio that varies with input current, and a low input forward current requirement. It is designed to operate over a broad industrial temperature range. The exact CTR and other specific parameters are dependent on the particular sub-model or binning of the LTV-3052 part, so it is important to consult the datasheet for the precise specifications required for a specific application.
