HCPL-2731-000E

Transistor, Photovoltaic Output Optoisolators Overview

The HCPL-2731-000E is a high-speed optocoupler manufactured by Broadcom Limited, featuring two independent channels within an 8-pin PDIP package. It utilizes Photodarlington output transistors to provide robust signal isolation with a rated insulation voltage of 3750 Vrms. The device supports data rates up to 100 kb/s and operates over an extended temperature range from -40°C to +85°C. Key electrical specifications include a maximum collector current of 60 mA per channel, a forward current of 20 mA, and a typical current transfer ratio of 1800%. Power dissipation is limited to 135 mW, ensuring reliable performance in industrial applications requiring galvanic isolation.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Dual-channel architecture providing independent signal paths for complex circuit isolation
• Photodarlington output configuration delivering high current gain and drive capability
• High insulation voltage rating ensuring safety compliance in isolated power systems
• Through-hole mounting compatibility for standard PCB assembly processes

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial automation control systems requiring galvanic isolation
• Power supply feedback loops for voltage regulation
• Signal interfacing between microcontrollers and high-voltage loads
• Data communication links in noisy electromagnetic environments

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix code against official Broadcom documentation to confirm packaging type and insulation ratings. The 000E suffix typically denotes tube packaging with 3750 Vrms isolation, whereas other suffixes may indicate reel packaging or higher voltage ratings such as 5000 Vrms. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability varies by region and production cycle.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when dual-channel isolation with moderate speed requirements is necessary. The Photodarlington output offers higher current handling compared to logic gate outputs but exhibits slower switching speeds. Ensure the application voltage does not exceed the 3750 Vrms isolation limit. Consider thermal management due to the 135 mW power dissipation constraint in enclosed environments.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the HCPL series of high-speed optocouplers from Broadcom. The series includes variants with different output types, such as Totem Pole (HCPL-2231) for faster switching, and varying insulation voltages. The HCPL-2731 specifically targets applications needing balanced performance between speed and drive strength.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include HCPL-2731-520E, which shares identical electrical characteristics but features 5000 Vrms isolation and comes in a gull-wing DIP package with reel packaging. Verify pinout compatibility and insulation voltage requirements before substitution.
