AT350
The AT350 is a high-speed gate-driver optocoupler designed for isolated signal transfer between low-voltage control stages and high-voltage switching devices such as IGBTs and MOSFETs. It provides fast propagation characteristics, stable output drive capability, and electrical isolation suitable for motor drives, solar inverters, UPS units, and other industrial power systems.
Its SO-8 surface-mount package supports PCB designs where board space and thermal performance are important. The device operates across a wide supply range, features low power consumption, and maintains consistent switching behavior in environments with electrical noise. High common-mode transient immunity supports reliable operation in EMI-exposed circuits.
The AT350 meets standard insulation requirements and supports long-term operation across industrial temperature conditions. Its characteristics make it appropriate for use in gate-drive stages where isolation, timing accuracy, and device compatibility are required.
