3A Gate Drive Optocoupler in 11mm SSO8 Package

Currently Viewing:

The ACNU-3410 is a 3A gate drive optocoupler device  in the 11mm SSO-8 package designed for high voltage, space constrained industrial applications including 600VAC motor drives and 1kVDC solar inverters. The new package platform features wide 11mm creepage and 10.5mm clearance, high insulation voltage and a compact package footprint, providing enhanced high voltage protection and signal isolation in tight spaces.
The ACNU-3410 is an upgrade and 40% smaller to the popular HCNW/ACNW in 400mil DIP-8 package. It 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.
