ACPL-339J-500E

Overview

The ACPL-339J-500E is a smart gate drive optocoupler designed for isolating, driving, and protecting Silicon Carbide (SiC) MOSFETs. It features a dual-output architecture optimized for high-side and low-side buffer stages with a minimum output peak current of 1A. The device integrates internal active timing control to prevent cross-conduction and minimize switching losses. Key electrical parameters include a 5000 Vrms isolation voltage, 40 ns rise and fall times, and a maximum continuous output current of 5.5 A. It operates within a temperature range of -40°C to 105°C and utilizes a 16-pin SOIC package.
