Additional features

The ACNT-H343 is a 5A gate drive optocoupler device in the 15mm SSO-8 package designed for high voltage, space constrained industrial applications including 690VAC motor drives and 1.5kVDC solar inverters.The new package platform features wide 15mm creepage and 14.2mm clearance, high insulation voltage and a compact package footprint, providing enhanced high voltage protection and signal isolation in tight spaces.

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