ACPL-5631L-200

Overview

The ACPL-5631L-200 is a high-speed, dual-channel logic output optocoupler manufactured by Broadcom Limited. It features a hermetically sealed ceramic DIP-8 package with gold-plated leads, designed for Class H reliability. The device operates at a data rate of 10 MBd with a common mode transient immunity (CMTI) of 1 kV/µs. Key electrical parameters include a forward current of 20 mA, forward voltage of 1.5 V, and reverse voltage of 5 V. Output characteristics consist of an open collector configuration with Schottky clamping. Power dissipation is rated at 200 mW, with rise and fall times of 90 ns and 40 ns respectively.

Feature Summary

• Hermetically sealed construction in a ceramic DIP-8 package ensuring high reliability and environmental stability.
• Dual-channel design providing independent signal isolation within a single compact component.
• Schottky-clamped open-collector outputs to minimize storage time and enhance switching speed.
• High common mode transient immunity for robust performance in noisy industrial environments.

Applications

• Industrial automation control systems requiring galvanic isolation
• Power supply feedback loops for voltage regulation
• Communication interfaces demanding high-speed digital isolation

Procurement Notes

Verify the specific ordering suffix to confirm package type and reel quantity specifications. Ensure compatibility with existing PCB footprints for the 8-DIP ceramic package. Confirm that the hermetic seal meets the required environmental standards for the intended application environment. Cross-reference datasheet revisions to ensure parameter consistency with previous design iterations.

Selection Notes

Select this component when high-speed digital isolation is required alongside strict environmental durability. The dual-channel architecture reduces board space compared to single-channel alternatives. Verify that the 10 MBd data rate aligns with system timing requirements. Consider the ceramic package's thermal and mechanical properties if operating in harsh conditions where plastic packages may fail.

Part Context

This part belongs to the ACPL-5631L series of high-reliability optocouplers.
