MCT277SMT&R is listed in the Transistor, Photovoltaic Output Optoisolators range at ChipApex. The manufacturer field lists Isocom Components 2004 LTD. Its product description is OPTOISO 5.3KV 1CH TRANS W/BASE. Review the specifications below when checking this part for your BOM.
The MCT277SMT&R is a single-channel optoisolator manufactured by Isocom Components 2004 LTD. It features a transistor output with base access and provides galvanic isolation of 5300Vrms. The device operates within a temperature range of -55°C to 100°C and utilizes a surface-mount package. Key electrical characteristics include a maximum forward current of 60 mA, a collector-emitter saturation voltage of 400mV, and a typical switching time of 2µs for both turn-on and turn-off. The component is designed for DC input applications.
Verify the manufacturer designation carefully, as Isocom Components often sources products from major semiconductor manufacturers. Confirm the specific suffix and packaging type against official datasheets to ensure compatibility with existing designs. Check for obsolescence status and available alternatives if long-term supply is required.
Select this component when a single-channel isolation solution with a transistor output and base pin is required. Consider the 5300Vrms isolation rating and operating temperature range to ensure suitability for the target environment. Compare switching speeds and current transfer ratios against application requirements before finalizing the design.
This part belongs to the MCT2 series of optocouplers, which are widely used for general-purpose isolation. The MCT277 variant specifically offers a transistor output with a base connection, distinguishing it from standard transistor outputs without base access. This configuration allows for additional circuit flexibility in switching applications.
Public confirmed substitute part numbers: CNY172SR2M (onsemi). Verify pinout and electrical specifications match before substitution.
