ACPL-P480-520E

Overview

The ACPL-P480-520E is a high-speed logic output optocoupler manufactured by Broadcom Limited. It features a single channel with an AlGaAs LED input and a Schmitt trigger output stage, designed for robust signal isolation in noisy environments. Key electrical parameters include a maximum propagation delay of 350 ns, a rise time of 16 ns, and a fall time of 20 ns. The device supports a data rate of 5 MBd and provides an insulation voltage of 3750 Vrms. It operates within a temperature range of -40°C to +100°C, dissipates up to 210 mW, and accepts a forward current of 6 mA with a forward voltage of 1.5 V.

Feature Summary

• Integrates a Schmitt trigger at the output to eliminate noise-induced false triggering and ensure clean digital signal transitions.
• Provides high common-mode transient immunity of 20 kV/µs for reliable operation in electrically noisy industrial settings.
• Utilizes an AlGaAs LED coupled with a photo detector for efficient optical transmission and high-speed performance.

Applications

• Gate drive interface circuits for power electronics
• Industrial automation control systems requiring signal isolation
• Power supply feedback loops for voltage sensing

Procurement Notes

Verify component authenticity through authorized distributors due to limited availability status. Confirm RoHS compliance details prior to integration. Check lead times as stock may be restricted.
