As Tony points out, there will usually be some other parameter that changes along the way. This means that the the junction is.

I am assuming these are too light for the duty they are trying to perform and would like to try and replace them with irfp40 Mosfets.

To participate you need to register. So, if you’re looking for a mosfet to continuously carry 20 amps, you will probably need a mosfet irpf450 with current capacity 3 to 10 times 20 amps. The sum of the junction to case and the case to sink resistances is 0. Forums New posts Search forums.


This is determined by the V-I slope of the driver and RdsOn of the switch. You must eatasheet in or register to reply here. Replacement Transformer Started by ncag Today at 7: A bigger switch always puts a bigger Ciss load on the gate. For a better experience, please enable JavaScript in your browser before proceeding.

One of the pair of So, it will only carry 14 amps if you can keep irfpp450 case at 25C while it is pushing out 78 watts of heat. Tc is case temperature, not ambient.

Electrolytic caps are a prime suspect. Pins 11 and 14 are the 2 outputs of the chip.

A project I am doing right orfp450 needs to switch 60Amps DC. My rule of thumb is the impedance of each stage, where the ratio of impedances of successive stages should not exceed and ought to be in the 10 range, so that RC dynamic losses don’t dominate and exceed conduction losses.

Otherwise you’ll need to resort to cold water or refrigerated cooling. My circuit is 15 volts.

Pin 11 which the burned resistor connects to has a very low resistance to ground compared to pin It seems this “entry level” charger” has very little margin before exceeding the component limits. If so, can you suggest some part numbers? This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register.


I am attempting to repair a Powermax PM power supply unit. So when carrying 14 amps, it will be dissipating about 78 watts of heat. Potentiometer Questions Started by norbss Yesterday irdp450 One important fact that everyone need to be aware of when choosing mosfets, is that the current rating has a fine print disclaimer that causes problems if not taken into account.

Ken1 Member Mar 1, Let’s look at a few items from the datasheet. Welcome to our site! Doable in a cryogenics lab, but not really a practical value for most real world applications.

Datasheets, Manuals or Parts. But if increased current capacity is your only goal, there is a big trap you need to look out for. We need to recalculate everything again based on the new info.
