HCPL0730R2

Transistor, Photovoltaic Output Optoisolators Overview

The HCPL0730R2 is a dual-channel high-speed optocoupler manufactured by onsemi, formerly Fairchild Semiconductor. It features split Darlington phototransistor outputs designed for low input current and high gain applications. The device provides electrical isolation with an insulation voltage of 2500 Vrms. Key electrical parameters include a data rate of 100 kb/s, a collector-emitter saturation voltage of 0.4 V at 60 mA output current, and a typical current transfer ratio of 1600%. It operates within a temperature range of -40°C to +85°C and is housed in an 8-pin SOIC package.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the manufacturer origin carefully, as this component was originally developed by Fairchild Semiconductor and is now produced by onsemi following corporate acquisitions. Confirm the specific suffix R2 indicates tape and reel packaging if required for automated assembly. Check current availability status as legacy components may have limited stock or end-of-life implications. Ensure compliance with RoHS directives relevant to your region before procurement.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high gain is required from low drive currents in a dual-channel setup. The split Darlington architecture offers superior performance compared to standard phototransistor outputs. Consider the 100 kb/s speed limit for application timing constraints. Evaluate the 2500 Vrms isolation rating against system safety requirements. Compare power dissipation limits with thermal management capabilities in the final enclosure design.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the HCPL-073x series of high-speed optocouplers. It shares architectural similarities with the HCPL-0730 but differs in packaging and manufacturing lineage. The series is characterized by its use of split Darlington outputs to achieve high current transfer ratios while maintaining low input current demands. It serves as a bridge between low-power logic circuits and higher-power load drivers.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

The HCPL-0730R2 is functionally equivalent to the HCPL-0730 in tube packaging. Verify pinout compatibility with existing designs. Check for updated datasheets from onsemi regarding any minor parameter shifts. Ensure substitute parts maintain the same 8-SOIC footprint and isolation voltage ratings.
