MOC5009G

Logic Output Optoisolators Overview

The MOC5009G is a single-channel logic output optoisolator manufactured by Isocom Components. It features a Schmitt trigger input and a tri-state open collector output, designed for high-speed digital signal isolation with a data rate of 1MHz. The device provides robust electrical isolation with an insulation voltage of 5300Vrms and a common-mode transient immunity (CMTI) capability. Packaged in a standard 6-pin DIP configuration, it offers a maximum off-state voltage of 6V. This component is engineered to replace legacy parts while meeting modern industrial standards for noise immunity and signal integrity in isolated digital circuits.

Logic Output Optoisolators Feature Summary

• Integrates a Schmitt trigger input stage to ensure clean switching and noise rejection for digital signals.
• Provides tri-state output functionality allowing multiple devices to share communication lines effectively.
• Delivers high-voltage isolation capability suitable for protecting low-voltage control circuits from high-voltage loads.

Logic Output Optoisolators Applications

• Industrial automation systems requiring isolated digital communication interfaces.
• Microcontroller-based designs needing protection against high-voltage transients.
• Power supply feedback loops for signal isolation between primary and secondary sides.

Logic Output Optoisolators Procurement Notes

Verify the specific ordering suffix and package variant when sourcing, as manufacturers may offer different tape-and-reel or tube packaging options. Confirm that the supplier provides original manufacturer documentation to ensure the component meets the specified 5300Vrms isolation rating. Cross-reference the part number with official distributor catalogs to avoid counterfeit components, especially given the availability of similar legacy replacements in the market.

Logic Output Optoisolators Selection Notes

Select this component when a Schmitt trigger input is required to mitigate signal bounce or noise in digital isolation applications. The tri-state output makes it suitable for bus-oriented systems where multiple isolators must drive a common line without contention. Ensure the application voltage does not exceed the 6V off-state limit and that the isolation requirements align with the 5300Vrms rating. Consider thermal management if operating near maximum current limits.

Logic Output Optoisolators Part Context

The MOC5009G belongs to the MOC500 series of optocouplers produced by Isocom Components. This series is known for providing direct replacements for obsolete industry-standard logic output optoisolators. The company specializes in infrared optoelectronic devices, offering these components in various lead forms and packaging options to meet diverse manufacturing needs.
