Import Tips
• Provide package outline drawings showing 4-pin DIP configuration typical of optical isolators; include isolation voltage certification
• Declare exact CTR range and forward current specs to distinguish from general purpose transistors under different subheadings
• Ensure commercial invoice specifies 'optical coupled isolator' function; prepare for CBP requests for application circuit diagrams
