The G3VM-401AY1 is a standard type, 1-Form-A (SPST-NO) MOS FET relay designed for high-voltage switching applications. It operates with a load voltage of 400V and a continuous load current of 120mA. This relay features a high dielectric strength of 5,000 VAC between its input and output, ensuring robust isolation. Housed in a compact DIP4 package with PCB terminals, it has a maximum ON-state resistance of 35 Ω and requires a maximum trigger LED forward current of 3mA. Its high reliability and small footprint make it suitable for various applications, including test and measurement equipment, industrial controls, security systems, and medical devices.
