Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix code to confirm the exact Current Transfer Ratio binning, as variants within the HCPL-817 series differ significantly in gain specifications. Confirm that the PDIP-4 package style matches the target PCB footprint requirements. Check for end-of-life status or alternative sourcing options due to potential discontinuation of legacy components. Ensure compliance with RoHS directives if required for the specific manufacturing environment.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a moderate speed response with a CTR range of 130% to 260% is required. It is suitable for applications needing 5000 Vrms isolation in a compact four-pin form factor. Consider the 70 V collector-emitter voltage limit for load driving capabilities. Evaluate the 18 µs switching times against system timing constraints to ensure adequate performance for the intended data rate.

Transistor, Photovoltaic Output Optoisolators Part Context

This component belongs to the HCPL-817 family of transistor output optocouplers. The series is characterized by its use of gallium arsenide infrared LEDs coupled to silicon phototransistors. The family offers various CTR bins to accommodate different drive requirements while maintaining consistent electrical isolation and mechanical packaging standards across the product line.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes may include other HCPL-817 variants with adjusted CTR bins, such as HCPL-817-060E or HCPL-817-30AE, provided the gain specifications align with circuit design needs. Verify pinout compatibility and insulation voltage ratings before substitution.
