Our AC controller thyristor module is designed for high-current electrical systems such as tankless water heaters. Built with 90 A SCR thyristors, it offers reliable performance at 50–60 Hz with minimal energy loss. Glass-passivated junctions and the SOT-227B package ensure efficient thermal management and electrical isolation. Ideal for high-frequency AC switching with fast response and low gate current requirements.
Key Features:
90 A RMS current rating
60 V blocking voltage (VDRM)
Surge current up to 950 A
50–60 Hz frequency range
CE Recognized & RoHS compliant
Benefits:
Fast turn-on and turn-off
Low gate drive requirements
Low thermal resistance with glass-passivated junctions
2.5 kV isolation in compact SOT-227B package
Applications:
Perfect for tankless water heaters, industrial heaters, AC motor control, and other high-current AC switching systems.
