Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix designation when ordering, as variations such as ISP620-1X may indicate different packaging formats like tape and reel versus tube. Confirm RoHS compliance status directly with the supplier or manufacturer documentation prior to procurement, as availability and regulatory status can vary by production batch and distributor source.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when an AC-compatible input interface is required within a single-channel isolation architecture. The inverse-parallel LED structure eliminates the need for external rectification components on the input side. Ensure the application voltage does not exceed the 5300Vrms isolation rating and that the switching speed requirements align with the 4μs rise time specification.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the ISP620 series of optocouplers manufactured by Isocom Components 2004 LTD. The series includes variants such as the ISP620-2 and ISP620-4, which offer multiple channels within similar DIP packages.
