Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix '500E' confirms the reel packaging format when ordering. Ensure the procurement documentation explicitly lists compliance with IEC/EN/DIN EN 60747-5-5 standards for industrial use cases. Confirm that the component is sourced directly from authorized distributors to guarantee authenticity and traceability. Check for any recent product change notices regarding pinout or material composition updates.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a single channel with high current gain is required for digital signal isolation. The 8-pin DIP form factor facilitates easy integration into existing through-hole or surface-mount layouts. Consider the 100 kb/s speed limit when designing for higher baud rate applications, as faster alternatives exist within the same family. The wide operating temperature range makes it suitable for harsh industrial environments.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the HCPL-47xx series of low-power, high-gain optocouplers. It shares architectural similarities with the dual-channel HCPL-4731 but offers a single isolated path. The series is designed to replace older transistor-output optocouplers by providing significantly higher current transfer ratios while maintaining low input drive requirements.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

The HCPL-4701-100E serves as the tube-packaged equivalent of this reel-delivered part. Designers may also consider the HCPL-0701 for similar performance in different package styles. Verify pin compatibility and thermal characteristics when substituting with generic photodarlington optocouplers.
