Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm packaging configuration, as standard designations may vary by distributor. Ensure compliance with RoHS directives if required by the target application. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and avoid counterfeit components. Check for any recent product change notices that might affect mechanical or electrical specifications prior to final procurement.

Selection Notes

Select this component when high isolation voltage and moderate speed are required in a compact surface-mount form factor. The NPN output type suits applications needing open-collector switching capabilities. Evaluate the current transfer ratio requirements against the load conditions to ensure adequate drive capability. Consider the thermal management aspects given the 150 mW power dissipation limit in enclosed environments.
