Detailed Specs:

The MCT6SD optocoupler features a high isolation voltage of 5000 VRMS, providing robust electrical isolation between the input and output circuits. The collector-emitter voltage is 80V. The forward current of the LED is typically 20mA. The current transfer ratio (CTR) varies depending on the specific bin. The optocoupler is housed in a 6-pin small outline package (SOP), suitable for surface mount assembly. The operating temperature range is from -55°C to +100°C. The MCT6 series offers different CTR ranges to meet various application requirements. It is also lead-free and RoHS compliant.

In power supply applications, the MCT6SD provides isolation between the primary and secondary sides, enhancing safety and preventing ground loops. In motor control applications, it can be used to isolate the control circuitry from the high-voltage motor drive. In digital logic inputs, it can be used to isolate digital signals from noisy environments. The high isolation voltage and compact design make it a versatile solution for a wide range of isolation applications.
