IL755-1X001

Transistor, Photovoltaic Output Optoisolators Overview

The IL755-1X001 is a bidirectional input optoisolator manufactured by Vishay Semiconductor Opto Division. It features two Gallium Arsenide infrared emitting diodes coupled to a silicon NPN phototransistor with base access, housed in a 6-DIP package. The device provides 5300Vrms isolation voltage and supports AC or DC input types. Key electrical characteristics include a maximum forward current of 60mA, a typical forward voltage of 1.2V, and a minimum current transfer ratio of 1000% at 1mA. It operates within a temperature range of -55°C to 100°C.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Bidirectional input capability utilizing dual infrared emitting diodes for flexible signal routing
• High current transfer ratio enabled by the Darlington output structure with accessible base terminal
• Robust electrical insulation rated at 5300Vrms suitable for safe electrical isolation applications

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial control systems requiring bidirectional signal isolation
• Power supply feedback loops needing high gain and isolation
• Microcontroller interface circuits with bidirectional data transmission needs

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify that the specific suffix X001 corresponds to the 6-DIP package configuration as required by your PCB layout. Confirm RoHS3 compliance status if environmental regulations apply to your assembly process. Ensure the supplier provides documentation confirming the part is active, as availability may vary across distribution channels. Cross-reference the manufacturer part number with official datasheets to validate pinout compatibility before integration.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when bidirectional input functionality is necessary, distinguishing it from standard unidirectional optocouplers. The high CTR makes it suitable for driving loads with minimal input current. Consider the 6-DIP package constraints against available board space. Evaluate the 5300Vrms rating against system isolation requirements to ensure adequate safety margins for industrial environments.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the IL755 family of bidirectional optoisolators. Unlike the VOM618A which offers transistor outputs in SOP packages, or the VO0601 with open-drain logic outputs, the IL755 series specifically addresses applications requiring reversible signal flow through dual LED inputs. It complements Vishay's broader portfolio of isolated components by providing specialized bidirectional capabilities in a DIP format.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing designs by matching isolation voltage, pinout, and electrical characteristics with alternative bidirectional optocouplers from other manufacturers if this specific part is unavailable.
