HCPL0701R2

Transistor, Photovoltaic Output Optoisolators Overview

The HCPL0701R2 is a single-channel high-speed optocoupler from onsemi, featuring a split Darlington transistor output with an exposed base for enhanced performance. It provides 2500 Vrms isolation voltage and operates within a temperature range of -40°C to +85°C. The device supports a data rate of 100 kb/s with a typical propagation delay of 300 ns (turn-on) and 1.6 µs (turn-off). Key electrical parameters include a maximum forward current of 20 mA, a forward voltage of 1.25 V, and a collector output current of 60 mA. The current transfer ratio ranges from 500% to 2600% at 1.6 mA input. Packaged in an 8-SOIC surface-mount footprint, it is designed for low-current, high-gain applications requiring reliable signal transmission across isolated circuits.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix R2 indicates reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD handling protocols are followed during storage and assembly. Cross-reference datasheet revision dates to confirm parameter consistency. Validate thermal dissipation requirements against system constraints before final selection.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high gain is required with minimal input current. The split Darlington structure offers faster response than standard phototransistors. Consider the 8-SOIC package dimensions for PCB layout compatibility. Evaluate isolation voltage requirements against system safety standards. Compare propagation delays with other logic gate outputs if timing precision is critical.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the HCPL0700/0701 series of high-speed optocouplers. It shares architectural similarities with the HCPL0731 dual-channel variant but provides single-channel functionality. The series is designed for general-purpose digital isolation where moderate speed and high gain are prioritized over ultra-high bandwidth. It complements the HCPL0601 logic gate output family by offering higher current drive capability at lower speeds.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

HCPL0731R2 serves as a dual-channel alternative within the same product family. Verify pinout compatibility and channel count requirements before substitution. Check if the additional channel impacts board space or power budget constraints.
