ACPL-6650L

Overview

The ACPL-6650L is a high-speed, hermetic logic-output optocoupler manufactured by Broadcom Limited. It features four independent channels providing galvanic isolation with a rated insulation voltage of 1500 Vrms. The device supports data rates up to 10 Mb/s and includes Schottky clamping for enhanced performance. Key electrical parameters include a forward current of 20 mA, a forward voltage of 1.55 V, and an output current capability of 25 mA. It operates within a temperature range of -55°C to +125°C and utilizes a 16-pin Flat-Pack package suitable for through-hole mounting.

Feature Summary

• Hermetic flat-pack construction ensures reliability in harsh environments
• Schottky-clamped outputs provide fast switching speeds and improved noise immunity
• High common-mode transient immunity (CMTI) of 1 kV/µs protects against signal corruption
• Four-channel configuration allows compact multi-line isolation solutions

Applications

• High-speed digital communication interfaces requiring galvanic isolation
• Industrial automation systems with noisy electrical environments
• Power electronics control circuits needing precise timing isolation
• Medical equipment requiring strict safety isolation standards

Procurement Notes

Verify the specific suffix code on the component marking to ensure it matches the ACPL-6650L designation exactly. Confirm that the package type is the 16-lead Flat-Pack variant. Check datasheet revisions for any updates to mechanical dimensions or thermal characteristics before finalizing procurement specifications.

Selection Notes

Select this component when high-speed data transmission is required alongside robust electrical isolation. Ensure the system voltage does not exceed the 1500 Vrms insulation rating. Consider the 20 mA forward current requirement for driver design. Verify that the operating temperature range meets the application's environmental demands.

Part Context

This part belongs to Broadcom's ACPL series of high-speed optocouplers. It is designed for applications demanding fast response times and reliable isolation. The series typically includes variants with different channel counts and output types. This specific model focuses on logic-level outputs for direct interfacing with digital circuits.

Replacement Considerations

Check for compatible parts within the same ACPL family that offer similar pinouts and electrical characteristics. Verify that any substitute maintains the 1500 Vrms isolation rating and 10 Mb/s data rate. Ensure the replacement package matches the 16-FlatPack form factor for board compatibility.
