Procurement Notes
Verify the specific suffix configuration against the manufacturer datasheet to ensure correct pinout and electrical characteristics. Confirm availability status as distribution channels may list discontinued or limited stock items. Cross-reference safety approval numbers such as UL and VDE if required for final product certification. Ensure the ordering part number matches the exact package type and current transfer ratio variant needed for the design.
Selection Notes
Select this component when high voltage isolation is required in a compact surface mount footprint. Consider the NPN phototransistor output type for standard switching applications. Verify that the 5000 Vrms isolation rating meets the system safety requirements. Check the operating temperature range compatibility with the intended environment. Compare current transfer ratio specifications if precise signal transmission is critical for the application.
Part Context
The EL816 series comprises single-channel optocouplers featuring an infrared LED coupled to a phototransistor. These devices are available in both DIP and SMD packages. The series is widely used for electrical isolation in various electronic circuits. The EL816(S)(TU)-V specifically denotes the surface mount variant with tape and reel packaging options. This family offers reliable performance for signal transmission across isolated barriers.
Replacement Considerations
Equivalent parts include the EL816(S)(X)(TA) and EL816S1(I)(TU)-V from Everlight. Verify pinout compatibility and electrical parameters before substitution. Ensure the replacement maintains the required isolation voltage and package dimensions.
