HCPL-2730#320

Transistor, Photovoltaic Output Optoisolators Overview

The HCPL-2730#320 is a dual-channel high-speed optocoupler manufactured by Broadcom Limited. It features a GaAsP LED optically coupled to integrated photodarlington detectors, providing electrical isolation between input and output circuits. The device operates at data rates up to 100 kb/s with a typical current transfer ratio of 1600%. It supports a maximum forward current of 20 mA and delivers an output current of 60 mA. Key electrical specifications include an insulation voltage of 5000 Vrms, a power dissipation of 135 mW, and a collector-emitter breakdown voltage of 7V. The component is housed in an 8-pin PDIP Gull Wing package designed for through-hole mounting.

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial networking systems requiring galvanic isolation
• Interface circuits connecting disparate voltage domains
• Digital signal transmission in noisy environments

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the exact suffix #320 against official Broadcom documentation to confirm lead time and availability status, as distribution channels may list varying stock levels or obsolescence notices. Ensure compliance with RoHS directives if required for specific manufacturing standards, noting that some listings indicate non-compliance. Cross-reference the manufacturer part number with distributor codes to prevent ordering errors due to packaging variations.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when dual-channel isolation is required within a single package footprint. The 5000 Vrms rating suits applications demanding robust barrier protection compared to lower-rated alternatives. Consider the photodarlington output type for applications needing higher current drive capability rather than logic-level outputs. Verify that the 100 kb/s speed meets the system timing requirements before finalizing the design.
