Essentially it's a diode whose forward conduction is switched on by the gate terminal.

Normally, the device is off, and looks like an open circuit. When you apply a momentary voltage to the gate, the device turns on, and looks like an ordinary rectifier. It remains on until the current drops below a certain threshold, at which point it turns off.
