HCPL2731SD

Transistor, Photovoltaic Output Optoisolators Overview

The HCPL2731SD is a dual-channel high-speed optocoupler featuring split Darlington transistor outputs. It provides an isolation voltage of 2500 Vrms and operates within a temperature range of -40°C to 85°C. Key electrical parameters include a maximum forward current of 20 mA, a typical rise time of 22 µs, and a typical fall time of 3 µs. The device utilizes an 8-SMD surface-mount package with鸥翼 (gull-wing) leads.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Dual-channel configuration for simultaneous signal isolation
• Split Darlington output structure for high gain capability
• High-speed switching performance suitable for logic applications

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial control systems requiring galvanic isolation
• Logic interface circuits between microcontrollers and power stages
• Signal transmission in noisy electromagnetic environments

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'SD' confirms the 8-SMD gull-wing package variant rather than through-hole versions. Confirm RoHS compliance status via the manufacturer's latest material declaration. Ensure the supplier provides official datasheets matching the onsemi part number to avoid counterfeit components.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when dual-channel isolation with high current transfer ratio is required in a compact surface-mount form factor. Compare against single-channel variants if only one isolated path is needed. Verify that the 2500 Vrms isolation rating meets the safety requirements of the target application circuit.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the HCPL-273x series of low input current, high gain split Darlington optocouplers. It shares functional similarities with the HCPL2730 but differs in channel count and packaging. The series is designed for applications demanding reliable signal transmission across isolated boundaries.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

HCPL2731SDM is the surface-mount equivalent with potentially higher isolation ratings. HCPL2731 is the general family designation. Cross-reference pinouts and isolation voltages before substitution.
