Broadcom ACFL-3161

The ACFL-3161 is a 10 A gate drive optocoupler device in the SSO-12 package designed for high-voltage, space-constrained industrial applications like motor drives and inverters. The new package features a 600 V CTI mold which reduces the creepage requirement due to high insulation voltage in a compact footprint.

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 less than 95 ns propagation delay, enabling high frequency switching to improve IGBT and SiC/GaN MOSFET driving efficiency.
