MOC8107M

Transistor, Photovoltaic Output Optoisolators Overview

The MOC8107M is a single-channel transistor output optocoupler manufactured by Fairchild Semiconductor. It integrates a Gallium Arsenide infrared emitting diode with an NPN phototransistor in a 6-pin DIP package. Key electrical parameters include a minimum collector-emitter breakdown voltage (BVCEO) of 70 V, a maximum forward current of 100 mA, and a forward voltage of 1.65 V. The device offers an isolation voltage of 5300 Vrms and supports a maximum collector current of 50 mA. It operates within a temperature range of -55°C to +100°C.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• High collector-emitter breakdown voltage of 70 V minimum for robust signal handling
• No base connection design minimizes noise susceptibility through very low coupled capacitance
• Closely matched current transfer ratio groups minimize unit-to-unit variation
• UL and VDE recognized for safety compliance in industrial applications

Transistor, Photovoltaic Output Optoisolators Applications

• Power supply regulators
• Digital logic inputs
• Microprocessor inputs
• Appliance sensor systems
• Industrial controls

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify component authenticity as the MOC8107M is listed as obsolete or discontinued by Fairchild Semiconductor. Confirm availability from authorized distributors or secondary market suppliers. Ensure the specific suffix matches required packaging options such as white package variants. Check RoHS compliance status and lead times carefully due to end-of-life status.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high isolation voltage and noise immunity are critical. The absence of a base pin reduces capacitive coupling compared to standard phototransistors. Consider the 70 V BVCEO rating for circuits requiring higher voltage margins. Verify that the CTR grouping meets the specific circuit gain requirements for reliable switching performance.

Transistor, Photovoltaic Output Optoisolators Part Context

The MOC8107M belongs to the MOC810X series of 6-pin DIP optocouplers designed for power supply applications. It shares architectural similarities with the CNY17 family but features specific enhancements like the no-base connection for improved noise performance. This series is widely used in isolated feedback loops and digital interface circuits where galvanic separation is required.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include MOC8106M and MOC8108M from the same series. Cross-reference with CNY17F4300W for similar isolation and package characteristics. Verify pinout compatibility and electrical ratings before substitution.
