Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix '7T' corresponds to the required tape and reel packaging format when ordering. Confirm that the 3750 Vrms isolation rating meets the safety requirements of the target application environment. Ensure the SOP-4 Miniflat footprint matches the design layout constraints. Cross-reference the CTR range of 80-160% against circuit sensitivity requirements to guarantee reliable switching performance under all operating conditions.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a surface-mount solution with moderate speed and high isolation voltage is required. Compare the 100 mA collector current capability against load requirements to ensure adequate drive strength. Evaluate the 6 µs rise time against signal frequency limitations to prevent distortion. Consider the thermal management needs given the 170 mW power dissipation limit in enclosed spaces.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the VOM61xA series of transistor output optocouplers from Vishay. It shares functional similarities with other models in the lineup but differs in packaging and specific electrical tolerances. The VOM618A-7T specifically utilizes the Miniflat form factor, distinguishing it from through-hole or standard SOP variants within the broader product family.
