Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix '36LE' against official Broadcom datasheets to confirm the exact package type and lead configuration, as suffixes define physical dimensions. Ensure compliance with RoHS directives if required by your design specifications. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a small form factor is required for isolating low-speed digital signals. Consider the 100% current transfer ratio for adequate gain in standard logic interfaces. Verify that the surface-mount footprint matches your board layout constraints compared to through-hole alternatives like the HCPL-817-36CE.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the HCPL-817 series of phototransistor optocouplers from Broadcom. The series is known for combining high isolation performance with various packaging options, including both through-hole DIP and surface-mount configurations. These components are widely used in general-purpose isolation applications where cost-effective and reliable signal transfer is necessary.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include other HCPL-817 variants such as HCPL-817-36CE for through-hole mounting or HCPL-817-000E for generic DIP packages. Ensure any replacement maintains the same 5000 Vrms isolation rating and compatible pinout to fit existing designs without modification.
