ACPL-5631L

Overview

The ACPL-5631L is a high-speed, two-channel optocoupler featuring hermetically sealed Class H construction in an 8-pin ceramic DIP package. It operates with a data rate of 10 Mb/s and provides 1500 VDC isolation voltage. The device utilizes photo IC outputs with open collector configurations and Schottky clamping to enhance switching performance. Key electrical parameters include a forward current of 20 mA, a forward voltage of 1.5 V, and a current transfer ratio of 100%. Rise and fall times are specified at 90 ns and 40 ns respectively, supporting a maximum power dissipation of 200 mW.

Feature Summary

• Hermetically sealed Class H construction for high reliability
• Schottky-clamped outputs for improved switching speed
• High common-mode transient immunity capability
• Dual-channel design within a single ceramic DIP package

Applications

• Industrial networking systems
• Isolation between diverse voltage levels
• High-speed digital signal transmission

Procurement Notes

Verify the specific suffix (e.g., -100, -200) to confirm lead frame material and package variant, as these affect mechanical compatibility. Ensure the selected part matches the required hermetic sealing specifications for the target environment. Confirm that the 8-pin DIP footprint aligns with the PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when high-speed data isolation exceeding 10 Mb/s is required alongside robust environmental protection. The Class H rating makes it suitable for demanding industrial applications where standard plastic packages may fail. Consider the 1500 VDC isolation barrier when designing circuits with significant potential differences between input and output grounds.

Part Context

This device belongs to the ACPL-5 series from Broadcom Limited, designed for high-reliability applications. The series emphasizes hermetic sealing and high-speed performance, distinguishing it from standard plastic-packaged optocouplers. It serves as a bridge for connecting low-voltage logic circuits to higher-voltage industrial environments safely.

Replacement Considerations

Direct replacements must match the 8-pin DIP hermetic package and 10 Mb/s speed class. Verify if alternative parts offer equivalent Class H sealing and 1500 VDC isolation. Check pinout compatibility to ensure seamless integration without redesigning the host circuit board.
