Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix '30CE' to confirm the surface-mount variant configuration, as datasheets may list multiple package options including through-hole DIP. Ensure compliance with RoHS directives by checking the detailed certification status provided by the manufacturer. Confirm that the ordering information matches the exact pinout and mechanical dimensions required for the target PCB footprint before finalizing procurement orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a single channel of galvanic isolation is required with moderate speed capabilities defined by 18 µs switching times. The 5000 Vrms isolation rating suits applications requiring robust noise immunity. Consider the NPN output type for compatibility with standard logic families. Verify thermal management requirements against the 200 mW power dissipation limit under worst-case operating conditions.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the HCPL-817 series of transistor output optocouplers from Broadcom Limited. The series offers various isolation voltages and package configurations. The HCPL-817-30CE specifically denotes the surface-mount version within this family, distinguished from through-hole variants like the HCPL-817-30AE by its physical packaging and mounting style while maintaining similar electrical performance characteristics.
