Procurement Notes
Verify the specific suffix VG against official Everlight documentation to confirm compliance requirements and pinout configuration. Confirm availability status as distribution channels may indicate limited stock or discontinuation. Ensure the selected packaging format matches the intended surface mount assembly process. Validate that the 5000 Vrms isolation rating meets the safety insulation requirements of the target application design.
Selection Notes
Select this component when surface mount technology is required for compact circuit board layouts. The NPN phototransistor output is suitable for digital switching applications requiring standard logic level interfacing. Verify that the operating temperature range and isolation voltage meet the specific environmental and safety standards of the end equipment. Consider the single-channel configuration for cost-effective isolation solutions.
