IL66-1

Transistor, Photovoltaic Output Optoisolators Overview

The IL66-1 is a single-channel optoisolator manufactured by Vishay Semiconductor Opto Division, featuring a photodarlington output with an integrated base resistor. It provides electrical isolation of 5300Vrms between input and output circuits. The device utilizes a 6-DIP through-hole package for standard mounting applications. Key electrical characteristics include a maximum forward current of 60mA and a collector-emitter saturation voltage of 1V. The component operates within a temperature range of -55°C to 100°C and offers high current transfer ratios suitable for interfacing logic circuits with higher power loads.

• Power supply feedback loops for voltage regulation
• Solid-state relay driver interfaces

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix and package variant when ordering, as Vishay may offer variations within the IL66 family. Confirm that the 6-DIP package matches your PCB footprint requirements. Check for any recent Product Change Notifications (PCNs) regarding manufacturing site or material updates. Ensure the procurement channel is authorized to guarantee component authenticity and traceability. Review the datasheet for absolute maximum ratings to prevent overstress during operation.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select the IL66-1 when high isolation voltage and high current gain are required without external base biasing components. Consider the slow switching speed inherent to darlington outputs; it is unsuitable for high-frequency data communication. Compare against single-transistor outputs if faster response times are critical. Verify that the 5300Vrms isolation rating meets the safety standards of the target application environment. Evaluate thermal management needs based on the expected forward current and ambient temperature conditions.

Transistor, Photovoltaic Output Optoisolators Part Context

The IL66-1 belongs to the IL66 series of optocouplers from Vishay Semiconductor Opto Division. This series includes variants with different channel counts and package styles, such as the quad-channel ILQ66-4. The IL66-1 specifically addresses applications needing a single isolated channel with high output current capability. It complements other Vishay optoelectronic products designed for industrial and consumer electronics isolation needs.
