Procurement Notes
Verify the specific suffix TU-V against official Everlight documentation to confirm surface-mount package configuration and tape-and-reel delivery format. Ensure compliance requirements match project specifications. Cross-reference datasheet revisions to confirm parameter consistency before finalizing procurement orders.
Selection Notes
Select this component when high isolation voltage is required in a compact surface-mount footprint. Verify that the 80 V output voltage rating meets circuit demands. Confirm that the CTR range aligns with drive requirements. Check thermal limits against operating environment conditions.
Part Context
This part belongs to the EL814S1 series of transistor-output optocouplers manufactured by Everlight Electronics. The series offers various packaging options including DIP and SMD configurations. The EL814S1(A)(TU)-V specifically denotes the surface-mount variant with defined reel packaging characteristics.
Replacement Considerations
Compatible substitutes within the same family include EL814S1(A)(TA)-V and EL814S1(A)(TD)-V. These variants share identical electrical characteristics but differ in package type or reel specification. Verify pinout compatibility before substitution.
