Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific manufacturer designation, as Isocom Components may source or distribute devices originally designed by Motorola. Confirm that the surface-mount variant matches the required footprint and soldering profile. Ensure compliance with RoHS directives if applicable to the procurement region. Check for any specific VDE 0884 marking requirements if isolation certification is mandatory for the end application.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a non-base-lead phototransistor output is required to reduce noise coupling in sensitive analog or digital circuits. The surface-mount form factor suits automated assembly processes. Consider the 300% typical CTR for driving logic inputs directly. Evaluate thermal constraints given the 0.15 W power dissipation limit in enclosed PCB layouts.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the MOC810x series of 6-pin DIP and SMD optoisolators. These devices are specifically engineered for power supply applications where tight current transfer ratio windows minimize unit-to-unit variation. The series ensures predictable open-loop gain characteristics, making them suitable for precision feedback control systems.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Equivalent parts include the MOC8103 from Fairchild Semiconductor and other manufacturers offering 6-pin SMD phototransistor optocouplers with similar isolation voltages and pinouts. Verify pin compatibility and CTR specifications before substitution.
