- Microcontroller interface circuits for noise immunity
Procurement Notes
Verify the component status as obsolete before procurement planning. Confirm availability through authorized distributors or approved substitute part numbers such as 4N27SR2M. Ensure that any replacement components meet the original electrical specifications and package dimensions to maintain system integrity without redesign.
Selection Notes
Select this component when high isolation voltage and surface-mount compatibility are required. The photovoltaic output type is suitable for applications needing zero quiescent current in the output stage. Consider the 6-SMD footprint constraints and verify thermal management requirements for the specific PCB layout during integration.
Part Context
This device belongs to the family of photovoltaic output optoisolators from onsemi. These components are distinct from transistor-output types by their ability to generate voltage directly from incident light, eliminating the need for external biasing on the output side. They are commonly used where low leakage and high reliability are critical.
Replacement Considerations
Direct substitutes include the 4N27SR2M. Verify pinout compatibility and electrical parameters against the original datasheet. Ensure the replacement maintains the 5.3 kV isolation rating and 6-SMD package style to fit existing board layouts.
