ACNU-3430-000E

Overview

The ACNU-3430-000E is a 5A gate drive optocoupler from the ACNU series, manufactured by Broadcom Limited. It features a single channel with a wide-body 11mm SSO-8 (SO-8 Stretched) package designed for high-voltage, space-constrained industrial applications. The device provides an insulation voltage of 5000 Vrms and operates within a temperature range of -40°C to +110°C. Key electrical parameters include a maximum DC forward current of 25 mA, a typical rise time of 20 ns, and a fall time of 10 ns. It supports an output supply voltage of 15V to 30V and has a power dissipation rating of 850 mW.

Feature Summary

• High common mode transient immunity exceeding 100 kV/μs to prevent erroneous switching in noisy environments
• Wide-body 11mm SSO-8 package design enabling safe creepage and clearance distances for high-voltage isolation
• Fast propagation characteristics with 20 ns rise and 10 ns fall times for precise gate drive control

Applications

• 600VAC motor drives
• Industrial inverters
• Switched-mode power supplies (SMPS)
• High-voltage isolated gate driver circuits

Procurement Notes

Verify the specific suffix 'E' indicates RoHS compliance as per manufacturer standards. Confirm the package type is the 11mm SSO-8 variant, distinct from standard SO-8 packages. Ensure the ordering part number matches ACNU-3430-000E exactly, as variations like ACNW3430 may exist with different packaging or minor specification differences. Cross-reference the datasheet revision date to ensure compatibility with current design requirements.

Selection Notes

Select this component when high isolation voltage and compact form factor are critical. The 11mm SSO-8 package is suitable for applications requiring enhanced safety clearance compared to standard packages. Consider the 5A peak output current capability for driving medium-power MOSFETs or IGBTs. Verify that the system's common mode noise environment does not exceed the specified CMTI rating to ensure reliable operation without false triggering.

Part Context

This device belongs to the ACNU series of gate drive optocouplers, which are engineered for robust performance in electric vehicle and industrial power conversion systems. The series emphasizes high reliability and fast switching speeds. The ACNU-3430-000E specifically targets applications where space is limited but high voltage isolation is mandatory, offering a balance between performance and physical footprint.

Replacement Considerations

The ACNW3430-000E is a related variant within the same product family. Verify if the W-series suffix denotes a specific packaging or qualification difference. Direct substitution requires confirming identical pinout, package dimensions, and electrical specifications against the target application's constraints.
