Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'GR' against official Isocom documentation to confirm lead-free compliance and tape-and-reel packaging status. Ensure the 4-DIP pinout matches the target PCB footprint. Confirm that the 5300Vrms isolation rating meets the safety requirements of the end application environment. Cross-reference the CTR specifications if precise gain matching is required for the design.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a single-channel isolation barrier is needed with high voltage withstand capability. The 4-pin DIP format simplifies through-hole assembly compared to surface-mount alternatives. Consider the 2μs/3μs switching speeds for moderate-frequency digital signals. Evaluate the -30°C to 100°C operating range against environmental conditions. Compare against other TLP621-series variants if multiple channels or different output types are necessary.
