MOC8111M

Transistor, Photovoltaic Output Optoisolators Overview

The MOC8111M is a 6-pin DIP transistor output optocoupler featuring a Gallium Arsenide infrared emitting diode coupled with an NPN phototransistor. The device provides high isolation voltage of 7500 VAC peak for one second and maintains a minimum collector-emitter breakdown voltage (BVCEO) of 70 Volts. It offers a selected current transfer ratio group with a minimum value of 20%. The internal design excludes base connection to external pins, enhancing noise immunity.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• High isolation voltage capability of 7500 VAC peak for one second duration
• NPN phototransistor output with no base connection bonded to external pin
• Minimum BVCEO rating of 70 Volts for robust operation
• Selected current transfer ratio group ensuring a minimum of 20% performance

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 the specific suffix 'M' confirms the 20% minimum current transfer ratio group as documented in Fairchild Semiconductor datasheets. Confirm package type is 6-Pin DIP. Ensure UL recognition file E90700 and IEC60747-5-2 approval status are required for your application compliance. Cross-reference ordering options if V suffix is needed for specific approvals.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high noise immunity is required due to the unconnected base terminal on the phototransistor. The 70V BVCEO rating suits applications requiring moderate voltage blocking capabilities between input and output circuits. The 20% CTR minimum ensures reliable switching for digital logic interfaces without excessive drive current requirements.

Transistor, Photovoltaic Output Optoisolators Part Context

The MOC8111M belongs to the MOC811XM series of 6-pin DIP optocouplers designed primarily for power supply applications. This series includes variants with different current transfer ratios, such as the MOC8112M (50% min) and MOC8113M (100% min). The family shares common packaging and isolation characteristics but differs in gain specifications.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Equivalent parts include MOC8111TVM from Fairchild Semiconductor. Other series members like MOC8112M or MOC8113M offer higher CTR but may require circuit adjustment. Generic replacements must match the 6-Pin DIP package and verify similar isolation voltage ratings.
