Procurement Notes

Verify the specific suffix 'GBSMT&R' against official manufacturer documentation to confirm exact lead frame material and tape-and-reel packaging specifications. Ensure the component meets required safety certifications such as UL or VDE if applicable to your design. Cross-reference the datasheet revision date to confirm parameter validity before finalizing procurement orders.

Selection Notes

Select this component when a compact, surface-mount solution is required for isolating low-speed digital signals. The 5300 Vrms isolation rating makes it suitable for applications involving significant potential differences between circuits. Consider the 4 µs rise time for timing constraints in your specific signal path requirements.

Part Context

This part belongs to the ISP817 series of high-density mounting phototransistor optically coupled isolators from Isocom Components.
