ACNV2601-000E

Overview

The ACNV2601-000E is a high-speed, single-channel digital optocoupler from the ACNV series by Broadcom Limited. It integrates an AlGaAs light-emitting diode with an integrated photodetector in a widebody 10-DIP package. The device supports data rates up to 10 MBd and provides a high isolation voltage of 7500 Vrms. Key electrical parameters include a typical rise time of 25 ns and fall time of 10 ns, with a maximum forward current of 20 mA and output current of 50 mA. It operates within a temperature range of -40°C to +105°C.

Feature Summary

• High insulation voltage capability of 7500 Vrms for robust signal isolation
• Fast switching performance with 10 MBd data rate and low propagation delay
• Wide operating temperature range suitable for demanding industrial environments

Applications

• Industrial automation control systems requiring galvanic isolation
• Power supply feedback loops for noise immunity
• Digital communication interfaces needing high common-mode transient immunity

Procurement Notes

Verify the specific suffix (e.g., -000E) to confirm the 10-DIP through-hole package variant, as other suffixes may indicate surface-mount packages like -500E. Ensure compliance with RoHS directives if required for your assembly process. Confirm lead times directly with authorized distributors, as availability varies. Cross-reference the datasheet revision to ensure compatibility with your design specifications regarding pinout and electrical characteristics.

Selection Notes

Select this component when high isolation voltage and fast digital signaling are critical. The 10-DIP package facilitates easy prototyping and through-hole mounting. Consider the 7500 Vrms rating for applications with high potential differences between input and output circuits. The open-collector output requires appropriate pull-up resistor selection based on the target logic voltage levels.

Part Context

This part belongs to Broadcom's ACNV family of high-insulation voltage optocouplers. It is designed to replace older HCPL-2601 variants where higher isolation voltage is required. The ACNV series offers improved common-mode transient immunity compared to standard optocouplers, making it suitable for noisy power electronics environments.

Replacement Considerations

Direct pin-compatible replacements within the same package should be verified against the datasheet. Check if alternative parts meet the 7500 Vrms isolation requirement and 10 MBd speed. Surface-mount equivalents like ACNV2601-500E require PCB layout changes.
