Let’s look at a few items from the datasheet. Doable in a cryogenics lab, but not really a practical value for most real world applications.

You must log in or register to datasbeet here. Lets take that number down to the graph at Figure 4. Maybe a little overkill but, other than the copper plates that carry the current, there is no heatsink. 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.
If the case is at 25C, the junction is at 94C.
I am assuming these are too light for the duty. Give them a good look, especially those close to the hot heat sink. You haven’t said what how you are using the mosfet, so it’s difficult to accurately answer your question. The sum of the junction to case and the case to sink resistances is 0. Datazheet circuit is 15 volts. A project I am doing right now needs to switch 60Amps DC.

There is also a visible crack in the case of the same Mosfet. I am attempting to repair a Powermax PM power supply unit. Articles Top Articles Search resources.
Ken1 Member Mar 1, Datasgeet, Manuals or Parts. But if increased current capacity is your only goal, there is a big trap you need to look out for.
One of the pair of This is determined by the V-I slope of the driver and RdsOn of the switch. They are mounted on a large aluminum heatsink and the unit also has a cooling fan. Tc is case temperature, not ambient.

Pin 11 which the burned resistor connects to has a very low resistance to ground compared to pin We need to recalculate everything again based on the new info. Nice power supply by the way.
So, at 78 watts, the junction is 69 degrees hotter than the case. As Tony points out, there will usually be some other parameter that changes along the way. It comes down to the fact that the current rating of most mosfets is a calculated number as to what current will put the junction temperature at it’s failure point when the case is at 25C.
Potentiometer Questions Started by norbss Yesterday at Thread starter Ken1 Start date Feb 28, The unit is relatively new and hasn’t seen much use. What dataasheet you doing with it? Ken1 Member Feb 28, I am assuming these are too light for the duty they are trying to perform and would like to try and replace them with heavier Mosfets. If the impedance gain or resistance gain is too high, you need more stages of MOSFET buffering to prevent overloading the gate dataaheet due to Qgs charge switch losses and switch frequency.
So it will only handle 14 amps continuous if the case is kept at 25C all of the time. I am using four amp mosfets.
It seems this “entry level” charger” has very little margin before exceeding the component limits. Take a look at this one.
