ILD755-1X017

Transistor, Photovoltaic Output Optoisolators Overview

The ILD755-1X017 is a bidirectional input optically coupled isolator manufactured by Vishay Semiconductor Opto Division. It features two Gallium Arsenide infrared emitting diodes coupled to a silicon NPN photodarlington output, providing high isolation capabilities with a rated insulation voltage of 5300 Vrms. The device operates within a temperature range of -55°C to +100°C and supports a maximum forward current of 60 mA. Key electrical parameters include a minimum current transfer ratio of 750% at 2 mA, a maximum collector-emitter saturation voltage of 500 mV, and a power dissipation rating of 400 mW. It is housed in an 8-SMD package.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Bidirectional input configuration utilizing dual Gallium Arsenide infrared emitting diodes for flexible signal routing.
• High-gain silicon NPN photodarlington output stage designed for efficient signal transmission across isolation barriers.
• Robust electrical isolation performance rated at 5300 Vrms to protect sensitive circuitry from high-voltage transients.

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial automation systems requiring reliable signal isolation between control logic and high-voltage actuators.
• Power supply circuits needing feedback isolation for accurate regulation and safety compliance.
• Microprocessor interface applications where galvanic separation is required to prevent ground loops and noise interference.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix '1X017' against the official Vishay datasheet to ensure correct package type and tape/reel specifications. Confirm that the bidirectional input variant matches the design requirements, as standard unidirectional versions may differ. Check RoHS compliance status and lead-free availability directly through authorized distributors or the manufacturer's official documentation before placing orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when bidirectional signal isolation is necessary within a single package, reducing board space compared to discrete solutions. Ensure the system voltage does not exceed the 5300 Vrms isolation rating and that the 750% CTR meets the drive requirements of the receiving circuit. Consider the 8-SMD form factor for surface-mount assembly constraints and verify thermal management needs given the 400 mW power dissipation limit.

Transistor, Photovoltaic Output Optoisolators Part Context

The ILD755 series represents Vishay's specialized line of optocouplers featuring unique bidirectional input structures. Unlike conventional optocouplers with a single LED input, this series integrates two diodes to allow signal flow in either direction. This architecture distinguishes it from standard transistor-output devices like the ILD74, offering enhanced flexibility for complex isolation tasks in industrial and power electronics applications.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative Vishay models such as the IL755 series, ensuring identical pinout and electrical characteristics. Consult official cross-reference guides for potential equivalents, but confirm bidirectional functionality specifically, as many standard optocouplers lack this feature.
