HCPL-817-56CE

Transistor, Photovoltaic Output Optoisolators Overview

The HCPL-817-56CE is a single-channel transistor output optocoupler from the Broadcom HCPL series. It features a surface-mount DIP-4 package with gull-wing leads. Key electrical parameters include a maximum forward voltage of 1.4V, a typical rise time of 4μs, and a typical fall time of 3μs. The device offers an isolation voltage of 5000Vrms and operates within a temperature range of -30°C to 100°C. Current transfer ratio specifications vary by source, with values ranging from 200% to 600% at specific test currents.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Provides galvanic isolation between input and output circuits using a DC input and NPN phototransistor output configuration.
• Designed for surface-mount assembly in a compact four-pin dual in-line package.
• Certified to international safety standards including UL, IEC, EN, and CSA for industrial applications.

Transistor, Photovoltaic Output Optoisolators Applications

• General-purpose signal isolation in industrial control systems
• Interface circuits for microcontrollers and logic gates
• Power supply feedback loops requiring high isolation voltage

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific current transfer ratio bin (e.g., 200%, 400%, or 600%) required for your design, as datasheets may list different ranges. Confirm the package variant matches the PCB footprint, noting discrepancies between through-hole and surface-mount descriptions in various distributor listings. Ensure compliance with RoHS directives if applicable to the project requirements.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a low-cost, single-channel isolation solution is needed for DC signals. Consider the 5000Vrms isolation rating for noise immunity in electrically noisy environments. Evaluate the switching speed limitations, as the rise and fall times are suitable for moderate-speed applications rather than high-frequency data transmission.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the HCPL series of optocouplers manufactured by Broadcom Limited. The series is widely used in consumer and industrial electronics for providing electrical isolation. The HCPL-817-56CE specifically denotes the surface-mount version with tape-and-reel packaging, distinguishing it from tube-packaged variants like the HCPL-817-36CE.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

The HCPL-817-36CE is a public confirmed substitute part number within the same family, offering similar electrical characteristics but typically packaged in tubes rather than reels. Verify pinout compatibility and thermal performance before substitution.
