The G3VM-21HR is a MOS FET relay from OMRON that has a low on-resistance of 20mΩ and can switch a large current of 2.5A. The relay is packaged in SOP and has a voltage rating of 1500Vrms, making it suitable for a wide range of applications, such as broadband, data loggers, and measuring instruments.
The G3VM-21HR is a surface‑mount MOS FET relay that offers a low on‑resistance of about 20 mΩ and can switch continuous loads up to 2.5 A. It is designed for industrial equipment and measurement instruments, with a compact SOP package and RoHS compliance.
The document lists the terminal layout, pin assignments, and internal wiring diagram, followed by detailed electrical performance data such as isolation voltage (1500 Vrms), on‑resistance (0.01 Ω), leakage current (10 nA), and LED drive requirements. Recommended operating conditions, including load voltage limits, temperature ranges, and LED forward current, are also provided to ensure reliable operation and proper reset of the relay.
