MCT5211300W is listed in the Transistor, Photovoltaic Output Optoisolators range at ChipApex. The manufacturer field lists onsemi. Its product description is OPTOISO 5.3KV TRANS W/BASE 6-DIP. Review the specifications below when checking this part for your BOM.
The onsemi MCT5211300W is a single-channel phototransistor output optocoupler housed in a 6-DIP package. It features an isolation voltage of 5300Vrms and supports a maximum collector current of 150mA with a collector-emitter voltage rating of 30V. The device exhibits a minimum current transfer ratio of 150% at a forward current of 1.6mA, with a typical forward voltage of 1.25V. Operating temperatures range from -55°C to 100°C.
Verify the specific suffix '300W' against official datasheets to confirm packaging and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for 6-DIP packages. Confirm availability status as distribution channels may list this part under legacy Fairchild branding or different stock codes.
Select this component when high isolation voltage and moderate speed are required. The integrated base allows for faster switching or higher gain adjustment compared to baseless variants. Verify thermal management requirements for the operating temperature range up to 100°C.
This part belongs to the MCT series of optocouplers, originally developed by Fairchild Semiconductor before its acquisition by onsemi. The series is known for providing cost-effective isolation solutions for general-purpose applications requiring robust performance in noisy electrical environments.
Direct substitutes include the MCT5211 and MCT5211SR2M. Verify pinout compatibility and ensure the replacement meets the same 5300Vrms isolation and 150mA output current requirements.
