MOC8108

Transistor, Photovoltaic Output Optoisolators Overview

The MOC8108 is a single-channel optocoupler featuring an infrared LED and NPN silicon phototransistor. It provides 5300Vrms isolation voltage with a collector-emitter breakdown of 70V. The device operates within a -55°C to 100°C temperature range. Key electrical parameters include a maximum DC forward current of 100mA, typical forward voltage of 1.15V, and saturation voltage of 400mV. Current transfer ratio ranges from 250% to 600% at 10mA input. Switching times are typically 2µs on and 3µs off.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., G, W) against the original design specification, as lead form variations exist. Confirm RoHS compliance status if required by project regulations. Check manufacturer documentation for end-of-life notices, as this component may be discontinued or superseded by newer revisions in the MOC810 series.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high isolation voltage and fast response are critical. Ensure the phototransistor output type matches the receiving circuit requirements. Verify that the 70V collector-emitter voltage rating exceeds the load voltage. Consider the 6-DIP package constraints for PCB layout and mounting space availability.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the MOC810 series of non-base lead optically coupled isolators. It is functionally similar to other industry-standard transistor-output optocouplers like the CNY17 series. The absence of a base connection simplifies circuit design while maintaining standard DIP packaging compatibility.
