No because a mosfet does not work the same as a thyristor. In a thyristor the current flows even when the gate pulse is removed, until the current stops. That is not the case for a FET.
HOLDING CURRENT: The minimum value of current that must be there to provide a path between anode and cathode to flow anode current and thus maintain a thyristor in the on state.0 LATCHING CURRENT: The minimum anode current required to maintain a thyristor in on-state immediately after a thyristor has be triggered on. IL>IHrate of flow of charge is known as current
It is the rated maximum current that can be taken from the transformer. This is equal to the VA rating divided by the output voltage. So a 6 kVA 240 v transformer would have a maximum current rating of 6000/240 or 25 amps.

A current rating of a fuse is designed to open a circuit at a specific current flow. This rating is imprinted on the fuse and lets you know what the maximum amount of current the fuse is designed to open at. A fuse is in the circuit to protect the conductor that the current flows through. Never over fuse a conductor's current carrying capacity.
There are two diode ratings. One is the forward current rating, and the other is the reverse breakdown voltage rating. The forward current rating is the maximum current that the diode can conduct before failing, and the reverse breakdown voltage rating is the maximum reverse voltage that can be applied before failing. Of course, the reverse voltage rating has a different meaning in a zener diode, but this answer applies to ordinary diodes.
Current depends on the Wattage and the voltage rating of the device.
The term "Forced commutation" is used when a thyristor is turned off using external components. If a thyristor is used in a DC circuit, when first turned on, it will stay on until the current goes to zero. To turn off the thyristor it is possible to use a Forced commutation circuit. The circuit creates a reverse voltage over the thyristor (and a small reverse current) for a short time, but long enough to turn off the thyristor. A simple circuit consist of a precharged capacitor and a switch (e.g. another thyristor) parallel to the thyristor. When the switch is closed, the current is supplied by the capacitor for a short while. This cause a reversed voltage over the thyristor, and the thyristor is turned off.
A thyristor is a rectifier semiconductor between two electrodes that permit unidirectional flow in anodes and cathodes.The flow of the current can be switched by a gate electrode that controls main driven electrical devices.To check a thyristor the current flow (between emitter/collector terminals) is checked.Then a small base current is applied to see if the thyristor functions as a switch.
It depends on the surround material, temperature, type of cable, and what you mean by "maximum current rating". Typically a maximum load current rating will be specified, such as 15A; this means you can push 15A through that cable nonstop without damaging it (it won't overheat). You might have a short time rating as well, such as a 4 hour rating, where the cable can handle runing 22A for 4 hours if the surrounding temperature is kept to some value, though this may slightly degrade the insulation. There's also a fusing current rating for many cables. At this current, the cable will eventually melt (like a fuse).
It is the rated maximum current that can be taken from the transformer. This is equal to the VA rating divided by the output voltage. So a 6 kVA 240 v transformer would have a maximum current rating of 6000/240 or 25 amps.
Holding current is a kind of Imin i.e., a minimum rating current which should not be decreased less than this limit so that SCR will be off(Maximum limit).Whereas latching current is again a limit which is Imini.e., a minimum current that should be there to make it on(Minimum limit).So obviously Holding current is more than latching current.If u still have the confusion go through the link below ALi RAZA
