ACNW3130-300E

Overview

The Broadcom ACNW3130-300E is a single-channel logic output optocoupler featuring an integrated IGBT gate driver. It utilizes a surface-mount DIP-8 gull-wing package and provides 5000 Vrms isolation voltage. The device delivers a peak output current of 2A for both sourcing and sinking operations, supporting supply voltages between 15V and 30V. Key electrical parameters include a maximum forward current of 16 mA, typical rise and fall times of 100 ns, and a maximum propagation delay of 500 ns. It operates within a temperature range of -40°C to +100°C.

Feature Summary

• Integrated high-current gate driver capable of directly driving power devices such as IGBTs, MOSFETs, and SiC FETs.
• High common-mode transient immunity ensures reliable signal transmission in electrically noisy environments.
• Low pulse width distortion maintains signal integrity across varying operating conditions.
• Compact surface-mount packaging facilitates automated assembly and space-constrained board designs.

Applications

• Industrial power supplies
• Photovoltaic inverters
• On-board chargers for electric vehicles
• DC motor control systems

Procurement Notes

Verify the specific suffix '300E' to confirm the surface-mount gull-wing package variant, as other suffixes may indicate through-hole or different isolation ratings. Ensure compatibility with RoHS directives if required by your manufacturing standards. Cross-reference the datasheet for exact thermal dissipation limits under your specific PCB layout conditions to prevent overheating during continuous operation.

Selection Notes

Select this component when a moderate 2A drive current is sufficient for the target power switch. Consider alternative models from the same family if higher peak currents (e.g., 5A) or stricter propagation delay specifications are required. Verify that the 5000 Vrms isolation rating meets the safety requirements of your circuit's primary-to-secondary barrier. Evaluate the 100 ns switching speed against your system's maximum switching frequency to avoid timing errors.

Part Context

This part belongs to the ACNW series of isolated gate drivers from Broadcom. The series is designed to replace discrete driver solutions by integrating the optocoupler and driver stage into a single package. This integration reduces component count and improves reliability in high-voltage power conversion applications compared to traditional discrete implementations.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult official Broadcom resources or authorized distributors for qualified alternatives that match the specific pinout, drive current, and isolation voltage requirements.
