You must log in or register to reply here. Doable in a cryogenics lab, but not really a practical value irfp50a most real world applications. So it will only handle 14 amps continuous if the case is kept at 25C all of the time.

The unit belongs to a neighbour and he datasyeet it just quit working; he doesn’t know if it was running hot before it quit. Datasheets, Manuals or Parts. There is also a visible crack in the case of the same Mosfet.


IRFPA Datasheet(PDF) – International Rectifier

As Tony points out, there will usually be some other parameter that irvp450a along the way. Welcome to our site! Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. Potentiometer Questions Started by norbss Yesterday at Replacement Transformer Started by ncag Today at 7: Nice power supply by the irfp4500a.

A project I am doing right now needs to switch 60Amps DC.

IRFP450A Datasheet PDF

Tc is case temperature, not ambient. 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. Often the input FETs are just the weak link and something else is the real culprit.

Let’s look at a few items from the datasheet. We need to recalculate everything again based on the new info. Take a look at this one.

Articles Top Articles Search resources. But if increased current capacity is your only goal, there is a big trap you need to look out for.

Lets take that number down to the graph at Figure 4. Not as easy as it sounds. Media New media New comments Search media. It comes down to the fact that the current rating of most ratasheet is a calculated number as to what current will put the junction temperature at it’s failure point when the case is at 25C.


This is the datasheet I used for this discussion. If the impedance gain or resistance gain is too high, you need more stages of MOSFET buffering to prevent overloading the gate resistors due to Qgs charge switch losses and switch frequency. You haven’t said what how you are using the mosfet, so it’s difficult to accurately answer your question.

Irrp450a the case is at 25C, the junction is at 94C. Forums New posts Search forums. So, at 78 watts, the junction is 69 degrees hotter than the case.

Pins 11 and 14 are the 2 outputs of the chip. I am using four amp mosfets. Ken1 Member Feb 28,
