HCPL-2731-500E

Transistor, Photovoltaic Output Optoisolators Overview

The HCPL-2731-500E is a dual-channel high-speed optocoupler manufactured by Broadcom Limited. It features Photodarlington outputs with a data rate of 100 kb/s and an isolation voltage of 3750 Vrms. The device operates within a temperature range of -40°C to +85°C, dissipating up to 135 mW. Key electrical parameters include a forward current of 20 mA, forward voltage of 1.4 V, reverse voltage of 5 V, output current of 60 mA, and a current transfer ratio of 1800%. It is housed in an 8-pin PDIP Gull Wing surface-mount package.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Integrates GaAsP light-emitting diodes with high-gain Photodarlington transistors for low-input-current operation.
• Provides robust electrical isolation between input and output circuits via a 3750 Vrms insulation barrier.
• Supports digital logic ground isolation and level shifting applications with high gain characteristics.

Transistor, Photovoltaic Output Optoisolators Applications

• Digital logic ground isolation
• Telephone ring detectors
• Level shifting circuits
• EIA RS-232C line receivers

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix '500E' to confirm the surface-mount gull-wing package variant, as opposed to through-hole DIP versions. Ensure compatibility with industrial networking systems requiring 100 kBd data rates. Confirm RoHS compliance status through official datasheets before finalizing procurement orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when dual-channel isolation with high gain is required for low-power LED drive conditions. The Photodarlington output offers higher current capacity than standard phototransistor variants. Consider the 100 kBd speed limit against system requirements; faster alternatives like the HCPL-2231 series are available if higher bandwidth is necessary.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the HCPL series of high-speed optocouplers from Broadcom. It is designed for industrial networking systems where diverse voltage levels must operate together safely. The product line emphasizes reliability and electrical isolation for sensitive electronic interfaces.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

The HCPL-2731-000E serves as a direct functional substitute but utilizes a through-hole PDIP-8 package instead of the SMT gull-wing form factor. Verify pinout compatibility and thermal management requirements when substituting between package types.
