MOC8104G

Transistor, Photovoltaic Output Optoisolators Overview

The MOC8104G is a single-channel optically coupled isolator manufactured by Isocom Components. It integrates an infrared emitting diode with an NPN silicon phototransistor in a 6-pin dual in-line plastic package where the base pin remains unconnected. The device provides high isolation voltage of 5300 Vrms and supports a maximum forward current of 60 mA. It operates within a temperature range of -55°C to 100°C and features a typical current transfer ratio of 50%.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• High isolation voltage capability for safe signal transmission between disparate potentials
• Unconnected base pin design enhances noise immunity in high electromagnetic interference environments
• Single-channel configuration with NPN phototransistor output

Transistor, Photovoltaic Output Optoisolators Applications

• DC motor controllers
• Industrial systems controllers
• Signal transmission between systems of different potentials and impedances

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify that the specific suffix 'G' corresponds to the through-hole lead form as documented in official Isocom Component datasheets. Confirm compliance with RoHS directives and UL recognition status (File No. E91231) prior to integration. Ensure the procurement specification matches the required lead spread and package type to avoid mechanical incompatibility during assembly.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high noise immunity is required due to its unconnected base pin architecture. It is suitable for applications demanding robust isolation between control circuits and power stages. Consider the 50% typical current transfer ratio for drive circuit sizing. Verify thermal management requirements against the specified operating temperature range of -55°C to 100°C.

Transistor, Photovoltaic Output Optoisolators Part Context

The MOC8104G belongs to the MOC810x series of non-base lead optically coupled isolators produced by Isocom Components. This series is designed for general-purpose isolation tasks, offering a standard 6-pin DIP footprint. It shares functional similarities with other industry-standard phototransistor optocouplers but is distinguished by its specific isolation ratings and certification approvals such as VDE and UL.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Compatible substitutes include MOC8101, MOC8102, MOC8103, MOC8105, CNY17F-4, and MOC8106XG, provided they meet the same electrical and mechanical specifications.
