ACNT-H313-000E

Overview

The ACNT-H313-000E is a high-speed IGBT gate drive optocoupler manufactured by Broadcom Limited. It features an integrated photo IC output capable of delivering up to 2.5A peak output current, designed for direct driving of power devices. The device utilizes a 15mm stretched SOIC-8 package to accommodate wide PCB creepage distances. Key electrical specifications include a minimum common mode transient immunity (CMTI) of 50kV/µs and a propagation delay of 150ns. It operates with a forward current of 12mA and provides isolation voltages supporting demanding industrial applications.

Feature Summary

• High-speed switching capability with 50kV/µs common mode transient immunity
• Integrated photo IC output stage providing 2.5A peak drive current
• Wide body 15mm stretched SOIC-8 package for enhanced isolation clearance

Applications

• Insulated Gate Bipolar Transistor (IGBT) gate driving in motor drives
• Inverter circuits for variable frequency drives (VFD)
• Industrial power supply isolated control interfaces

Procurement Notes

Verify the specific ordering suffix matches the required package variant, as the ACNT-H313 series includes different pinout or insulation configurations. Confirm that the 15mm stretched SOIC footprint aligns with the target PCB design rules. Ensure compliance with RoHS directives if applicable to the end product requirements. Cross-reference the datasheet revision date to confirm the latest electrical characteristics before finalizing component selection.

Selection Notes

Select this component when high CMTI is critical to prevent false triggering in noisy environments. The 2.5A output current supports direct driving of medium-power IGBTs without external buffers. Consider the 15mm package width if strict safety isolation standards require wider creepage distances than standard SOIC packages provide. Evaluate thermal dissipation capabilities within the system layout constraints.

Part Context

This part belongs to Broadcom's ACNT series of high-performance optocouplers specifically engineered for power electronics. Unlike standard logic output optocouplers, the ACNT-H313 integrates a dedicated output driver stage. This distinguishes it from lower-current variants like the HCPL-J31x series, which are intended for signal isolation rather than direct power device actuation.
