MOC8105G

Transistor, Photovoltaic Output Optoisolators Overview

The MOC8105G is a single-channel transistor output optocoupler manufactured by Isocom Components. It features an infrared LED coupled to an NPN silicon phototransistor in a 6-pin DIP package with an unconnected base pin. Key electrical parameters include a minimum collector-emitter breakdown voltage of 30 V, a nominal current transfer ratio of 65%, and a maximum dark power of 50 nA. The device supports a maximum forward current of 60 mA and offers a high isolation voltage of 7500 V. It operates within a temperature range of -40 °C to 100 °C.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Provides galvanic isolation between input and output circuits using an infrared LED and NPN phototransistor configuration.
• Features an unconnected base pin on the phototransistor side, allowing for external biasing or sensitivity adjustment if required.
• Designed for through-hole mounting in standard 6-pin dual in-line plastic packages.

Transistor, Photovoltaic Output Optoisolators Applications

• General-purpose signal isolation in industrial control systems
• Switch-mode power supply feedback loops
• Microcontroller interface circuits requiring electrical separation

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify that the specific suffix 'G' corresponds to the lead form or RoHS compliance status as defined by Isocom Components documentation. Confirm the manufacturer source, as Rochester Electronics also lists this part number. Ensure the procurement channel provides valid traceability for the specified component variant.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a single-channel isolation solution with a nominal current transfer ratio of 65% is required. The 7500 V isolation rating suits applications demanding high dielectric strength. Consider the 60 mA maximum forward current limit and the -40 °C to 100 °C operating range against system thermal constraints.

Transistor, Photovoltaic Output Optoisolators Part Context

The MOC8105 belongs to the MOC series of optically coupled isolators produced by Isocom Components. This series typically includes variants like the MOC8106X and MOC8107X, which share similar structural designs but may differ in specific electrical ratings or certification approvals such as UL or VDE recognition.
