How many AMP diode do I need?

How many AMP diode do I need?

The diode needs to have a voltage and amperage rating above that of the panel. Ex: If you have two 175 watt panels each at 42 volts, you will need (two) 8 Amp, 45-volt diodes. (175 watts / 42 volts) = 4.16 amps.

How much current can a diode handle?

When the voltage at the anode is higher than the cathode voltage, the diode is said to be “forward-biased,” since the electrical current is “moving forward.” The maximum amount of current that the diode can consistently conduct in a forward-biased state is 1 ampere.

What happens if current is too high?

If the current flow gets too high, the fuse will melt. This destroys the fuse, but protects the remainder of the circuit.

How much current can pass through a diode?

What is current rating of diode?

The rating is the continuous current limit of the Diode. If you use these with a 2 A or 6 A power supply makes no difference ….it’s the amount of load current that flows that is the limitation.

What is the best diode for reverse voltage power supply?

The reverse voltage it has to withstand is just the voltage driving the coil (12V) plus a fudge factor and the diodes mentioned are good for at least 75V and 300mA. With through hole, you can usually stand them on end. Pretty much any silicon switching diode will do. You can use a 1N914 or 1N4148 for sure.

What is the peak current rating of a 1A rectifier diode?

1N400X 1A rectifier diodes have a peak current rating of 30A. Clearly up to the job. Since eagle wants to operate the relay 45 times per second a proper snubber circuit that collapses the coil current faster than the simple single diode snubber is needed.

What voltage do I need for a TVS diode?

So a diode rated at 3A peak is needed and a 1N4148 will just fuse. of a switching transistor). V dt = – L dI Littelfuse make special TVS diodes. They have some technical information on their site that is worth a read.

How much current can a flyback diode withstand?

The flyback diode has to be able to handle the current produced by the collapsing magnetic field of the coil which is much much less than the current driving the coil. The reverse voltage it has to withstand is just the voltage driving the coil (12V) plus a fudge factor and the diodes mentioned are good for at least 75V and 300mA.
