Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'GRSMT&R' against official Isocom documentation to confirm lead frame material, tape-and-reel packaging dimensions, and RoHS compliance status. Ensure the ordering code matches the exact DIP-16 or SOIC-16 variant intended, as suffixes often dictate mechanical form factor and reel quantity. Cross-reference UL and VDE approval numbers directly with the manufacturer's certificate of conformity.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when designing circuits that require simultaneous isolation of four distinct signal paths within a limited board area. The 5300 Vrms insulation rating makes it suitable for applications demanding high safety margins between primary and secondary sides. Consider the 200% CTR for driving standard logic inputs without excessive base current requirements. Verify thermal management needs given the 100 °C maximum operating temperature limit.
