The G3VM-21GR1 is a single-pole, single-throw, normally open (SPST-NO) MOS FET relay designed for applications requiring a low product of output capacitance and on-resistance (C x R). It operates with a 20V maximum load voltage and can handle a continuous load current of up to 300 mA. Key features include a low typical ON-state resistance of 1 Ω, a low output capacitance of 5 pF, and fast switching times with a typical turn-on time of 0.13 ms. The device is housed in a 4-pin SOP package and is rated for an ambient operating temperature range of -20°C to +85°C. Its characteristics make it suitable for use in semiconductor test equipment, communication systems, and various industrial control circuits.
