SiC MOSFET and IGBT gate drive solution Broadcom ACPL-K33T-560E optocoupler with reinforced insulation
Avago Technologies ACPL-K33T Automotive 2.5 A Peak High Output Current SiC MOSFET and IGBT Gate Drive Optocoupler
Product Overview
The Avago Technologies ACPL-K33T is a 2.5 Amp Automotive R2Coupler Gate Drive Optocoupler designed for driving SiC MOSFET and IGBTs in AC-DC and DC-DC converters. It features an AlGaAs LED optically coupled to an integrated circuit with a power output stage, offering fast propagation delay and tight timing skew. The high operating voltage range of the output stage provides the necessary drive voltages for gate-controlled devices. This optocoupler delivers the voltage and high peak output current required for direct driving SiC MOSFET and IGBTs at high frequencies, enabling high-efficiency conversion. Avago R2Coupler isolation products provide reinforced insulation and reliability, crucial for safe signal isolation in automotive and high-temperature industrial applications.
