Product Description
Product Overview
The ACPL-K34T is an automotive-grade 2.5 A peak high output current MOSFET gate drive optocoupler featuring rail-to-rail output voltage. It integrates an AlGaAs LED with an IC power output stage, offering fast propagation delay and tight timing skew. Designed for driving power MOSFETs in AC-DC and DC-DC converters, it provides reinforced insulation critical for automotive and high-temperature industrial applications. Its high operating voltage range and peak output current capability make it ideal for direct driving power MOSFETs at high frequencies for efficient power conversion.
