Procurement Notes

Verify the specific suffix configuration against the manufacturer's official datasheet to ensure correct pinout and packaging variant. Confirm RoHS compliance status and relevant safety approvals such as UL or VDE recognition for your target market regulations. Cross-reference the part number with authorized distributors to avoid counterfeit components. Ensure the selected variant matches the required current transfer ratio specifications for your circuit design.

Selection Notes

Select this component when high isolation voltage is required in a compact surface-mount form factor. Consider the 50% nominal current transfer ratio for logic level interfacing applications. Verify that the 80 V collector-emitter breakdown voltage meets the load requirements. Ensure the operating temperature range aligns with the environmental conditions of the final assembly. Check compatibility with automated pick-and-place equipment due to the SMD package type.
