Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'SMT&R' to ensure correct surface mount tape and reel packaging configuration. Confirm that the manufacturer designation matches Isocom Components 2004 LTD, as cross-manufacturer equivalents may have different pinouts or electrical characteristics. Validate the 16-pin SMD footprint against your PCB design requirements before finalizing procurement orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when multiple isolated channels are required within a single package to save board space. Ensure the application supports AC input signals on the LED side. Verify that the 35V collector-emitter voltage rating exceeds the load voltage requirements. Check that the 20% minimum CTR meets the drive requirements of the receiving circuitry under all operating temperature conditions.
