Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'XC' against official Isocom documentation to confirm lead frame plating or tape-and-reel packaging details, as suffixes often denote manufacturing variations rather than functional changes. Ensure the procurement order explicitly references the full part number to distinguish it from other variants in the ISP847 or ISP817 series. Confirm RoHS compliance status if required by your assembly process.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a quad-channel phototransistor output isolator is required in a standard DIP-16 package. It is suitable for applications needing high density mounting and significant isolation voltage. Compare the 200% CTR and 35V Vceo against system requirements to ensure adequate noise immunity and switching performance. Consider thermal management capabilities given the 100°C maximum junction temperature limit.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the ISP817/ISP827/ISP847 family of high-density phototransistor optocouplers. These components are designed as industry-standard replacements for legacy parts, offering similar pinouts and electrical characteristics while incorporating modern manufacturing processes. The family provides options for varying Current Transfer Ratios (CTR) to suit different sensitivity requirements in isolation applications.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes may include the TLP621 or PC817 series equivalents, provided they meet the 5300V isolation and DIP-16 package constraints. Verify that replacement parts offer comparable CTR and breakdown voltage ratings to maintain circuit integrity.
