Product Overview

The Broadcom ACPL-H342/ACPL-K342 is a high-performance optocoupler designed for driving power IGBTs and MOSFETs in motor control inverter applications. It features an integrated AlGaAs LED and a power output stage, delivering high operating voltage and peak output current suitable for direct driving IGBTs up to 1200V/150A. Key advantages include an active Miller clamp, rail-to-rail output voltage, fast propagation delay for minimized dead time, and under-voltage lock-out protection. This optocoupler is ideal for AC and brushless DC motor drives, renewable energy inverters, industrial inverters, and switching power supplies, offering enhanced performance and reliability.
