ACPL-P484-000E

Overview

The ACPL-P484-000E is a single-channel high-speed optocoupler from Broadcom, featuring an AlGaAs LED and photodetector with a built-in Schmitt trigger for logic output. It operates within a temperature range of -40°C to +105°C and provides 3750 Vrms isolation voltage. The device supports data rates up to 10 Mb/s with typical rise and fall times of 6 ns. Key electrical parameters include a maximum forward current of 7 mA, a typical forward voltage of 1.5 V, and a reverse voltage rating of 5 V. It is housed in a surface-mount SOIC-Wide-6 package.

Feature Summary

• Integrates a Schmitt trigger at the output stage to ensure clean digital signal transmission and noise immunity.
• Delivers high common-mode transient immunity of 30 kV/µs for reliable operation in electrically noisy environments.
• Supports high-speed data communication with a 10 Mb/s data rate capability.
• Provides robust electrical isolation between input and output circuits via a 3750 Vrms insulation voltage.

Applications

• Industrial networking systems requiring isolated signal transmission
• Gate drive interfaces for intelligent power modules
• Digital communication channels in high-noise industrial environments

Procurement Notes

Verify the specific ordering suffix matches the required packaging configuration, as variants such as the 500E suffix indicate reel packaging while standard versions may use tape and reel or cut tape. Confirm that the surface-mount SOIC-Wide-6 footprint aligns with the target PCB design. Ensure compliance with RoHS directives and relevant safety certifications like UL 1577 and IEC standards for the intended application environment.

Selection Notes

Select this component when high-speed digital isolation is required alongside strong noise immunity. The integrated Schmitt trigger makes it suitable for applications where signal integrity is critical without external conditioning. Compare against other ACPL series devices if lower speed or different output types are needed. Verify thermal management requirements given the operating temperature range and power dissipation limits.

Part Context

This part belongs to the ACPL series of high-speed optocouplers designed by Broadcom Limited. The series focuses on providing reliable galvanic isolation for digital signals in demanding industrial and commercial applications. The P484 variant specifically targets gate drive and intelligent power module interfaces where fast switching and high CMR are essential.

Replacement Considerations
