ACPL-W21L-560E

Overview

The ACPL-W21L-560E is a high-speed single-channel optocoupler manufactured by Broadcom Limited. It features a data rate of 5 Mb/s and an isolation voltage of 5000 Vrms. The device utilizes a push-pull, totem pole output configuration with a maximum propagation delay of 250 ns for both low-to-high and high-to-low transitions. Key electrical parameters include a forward current of 2.2 mA, a forward voltage of 1.5 V, and an output current capability of 10 mA. The component supports a reverse voltage of 5 V and operates within a temperature range of -40°C to +105°C. It is housed in a surface-mount SSO package.

Feature Summary

• High-speed signal transmission capability at 5 Mb/s for efficient data isolation
• Robust electrical isolation rated at 5000 Vrms between input and output circuits
• Push-pull totem pole output structure providing strong drive capability
• Wide operating temperature range suitable for demanding industrial environments

Applications

• Industrial automation control systems requiring high-speed signal isolation
• Power supply feedback loops for isolated voltage regulation
• Communication interfaces needing galvanic isolation between different ground potentials
• Motor drive circuits for protecting control logic from high-voltage noise

Procurement Notes

Verify the specific ordering suffix matches the required packaging format, such as reel or cut tape, as indicated in official documentation. Confirm compliance with RoHS directives and relevant safety certifications like UL, IEC, and CSA before finalizing procurement. Ensure the supplier provides valid traceability documents and that the component lot codes align with quality requirements. Cross-reference the manufacturer part number with authorized distributor lists to avoid counterfeit risks.

Selection Notes

Select this component when a single channel with high-speed performance and strong isolation voltage is required. The push-pull output eliminates the need for external pull-up resistors, simplifying circuit design compared to open-collector alternatives. Consider the 250 ns propagation delay for timing-sensitive applications. Evaluate the thermal management needs given the wide operating temperature range and ensure the PCB layout accommodates the SSO package dimensions and creepage distances mandated by the isolation rating.
