ACNT-H343-000E

Overview

The ACNT-H343-000E is a 5 A gate drive optocoupler from Broadcom Limited, designed for high-voltage industrial applications. It features a 15 mm creepage distance and 14.2 mm clearance within an SSO-8 package. The device offers a common-mode transient immunity (CMTI) exceeding 100 kV/μs at V_CM = 1.5 kV. It supports IEC 60747-5-5 V reinforced insulation with a peak output current of 5.0 A and includes under-voltage lockout (UVLO). Operating temperatures range from -40°C to +105°C.

Feature Summary

• High common-mode transient immunity exceeding 100 kV/μs prevents false triggering in noisy environments
• Integrated under-voltage lockout ensures reliable switching protection
• Optimized propagation delay enables three times faster speed compared to previous generations

Applications

• 1500 V renewable energy inverters
• 690 V AC motor drives
• Static var generators and active power filters
• Industrial inverters

Procurement Notes
