ACNT-H343 5 A Gate Drive Optocoupler

Broadcom's ACNT-H343 is a 5 A gate drive optocoupler device in the 15 mm SSO-8 package designed for high voltage, space-constrained industrial applications including 690 VAC motor drives and 1500 V solar inverters.

The ACNT-H343 features common mode transient immunity (CMTI) greater than 100 kV/μs, preventing erroneous gate driver failures in noisy environments. The device has minimal propagation delay, three times faster than the previous generation, enabling high-frequency switching to improve efficiency in driving IGBT (insulated-gate bipolar transistor) and SiC/GaN MOSFET.
