Additional Details:

The G3VM-351GLTR requires a control voltage to activate the internal LED, which then generates a voltage through the photovoltaic cells. This voltage turns on the MOSFET, allowing current to flow between the output terminals. The switching speed is determined by the characteristics of the LED and MOSFET. The datasheet provides detailed specifications, including output capacitance, on-resistance, isolation voltage, and switching speed. The surface mount package facilitates automated assembly. The use of photovoltaic isolation eliminates the need for external power supplies for the gate drive circuit.
