ACNW3430-000E

Overview

The ACNW3430-000E is a single-channel gate driver optocoupler manufactured by Broadcom Limited. It provides 5A peak output current with a continuous output capability of 4A in both high and low states. The device features 5000Vrms isolation voltage and supports an output supply voltage range of 15V to 30V. Key electrical parameters include a maximum propagation delay of 150ns, typical rise and fall times of 20ns and 10ns respectively, and a minimum common-mode transient immunity of 100kV/µs. It operates within a temperature range of -40°C to +105°C and is housed in an 8-DIP package.

Feature Summary

• High-speed switching performance with low propagation delay and minimal pulse width distortion for precise gate control.
• Robust noise immunity characterized by high common-mode transient rejection capabilities suitable for electrically noisy environments.
• Integrated rail-to-rail output stage eliminates the need for external buffer circuits, simplifying design complexity.

Applications

• IGBT and MOSFET gate drive circuits
• AC and brushless DC motor drives

Procurement Notes

Verify the specific ordering suffix to confirm the packaging format, as the base part number may correspond to tube packaging while other suffixes indicate reel or cut tape options. Confirm that the selected variant meets the required insulation coordination standards, such as IEC 60747-5-5, for the intended safety application. Ensure the input forward current specifications align with the driving logic levels available in the system design.

Selection Notes

Select this component when high peak current drive capability is required for power switches without additional buffering stages. Consider the 8-DIP through-hole package for applications requiring robust mechanical mounting. Evaluate the thermal dissipation requirements against the specified power dissipation limits under continuous operation conditions at elevated ambient temperatures.
