JXT Semi provides high-performance and highly reliable optocoupler isolation products, designed to meet diverse market demands. These products are widely applied in energy systems and power grids, industrial automation equipment, consumer electronics, 5G/6G communication networks, automotive electronics, and medical devices.

The photo coupler product portfolio includes:

• Photo Transistor Output photo couplers
• Photo Triac photo couplers
• High-Speed photo couplers
• IGBT Gate Driver photo couplers

All photo coupler products feature high-isolation voltage designs and are certified by multiple international safety standards, including UL and VDE, ensuring reliability and safety even under demanding operating conditions.

Application Areas:

• Power Supplies: In DC-DC or AC-DC converters, optocouplers establish feedback loops to achieve precise voltage regulation and prevent high-voltage side faults from affecting the low-voltage side.
• Motor Drives & Inverters: Optocouplers isolate microcontrollers from IGBT/MOSFET driver circuits, protecting processors from high-frequency noise and voltage spikes.
• Industrial Interfaces: In RS-232, RS-485, or CAN bus communication systems, optocouplers provide signal isolation, eliminating ground loop issues and enhancing long-distance transmission stability and noise immunity.
• Home Appliances & Industrial Control: Used as isolation relays, optocouplers allow MCUs to safely control high-voltage AC loads (such as solenoids, heaters, or motors), ensuring both user safety and system protection.
