Heat sinks, Part 2: So, it will only carry 14 amps if you can keep the case at 25C while it is pushing out 78 watts of heat. I have heard of counterfeit parts on the market.

Part datsaheet Inventory Search. You need to know what affect other parameters may have on your circuit. Articles Top Articles Search resources. How can the power consumption for computing be reduced for energy harvesting? Your device tester would be a simple test circuit to supply this same DC current and voltage to the device under test mounted irfp460w the specific heat sink configuration.

You would like to verify component parameters by test before installing to avoid damage to the unit when the component fails. This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register.


This means that the the junction is. I am attempting to repair a Powermax PM power supply unit.

As Tony points out, there will usually be some other parameter that changes along the way. Maybe a little overkill but, other than the copper plates that carry the current, there is no heatsink.

Some things to be careful about: 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.

What are you doing with it? Once you had the DC voltage and Current and temperature rise data for a specific heatsink configuration, Your device tester would be a simple test circuit to supply this same DC current and voltage to the device under test mounted to the specific heat sink configuration.

Datasheets, Manuals or Parts. The time now is Digital multimeter appears to have measured voltages lower than expected. CMOS Technology file 1.

Electrolytic caps are a prime suspect. Even changing from thermal compound to an insulating thermal pad can alter the thermal resistance enough to invalidate your results. Equating complex number interms of the other 6.

They are mounted on a large aluminum heatsink and the unit also has a cooling fan. By continuing to use this site, you are consenting to our use of cookies. There is also a visible crack in the case of the same Mosfet. Give them a good look, especially those close to the hot heat sink.


IRFP460A MOSFET. Datasheet pdf. Equivalent

It seems that you bought some bad parts in that they failed immediately when installed in a plasma display you are working on.

Let’s look at a few items from the datasheet. Unless all of these factors are considered the calculation is at best a rough approximation. AF modulator in Transmitter what is the A? If the case is at 25C, the junction urfp460a at 94C.

PNP transistor not working 2. Losses in inductor of a boost converter 9. This actual working model must contain the actual drive circuitry and heat sink as well as any other associated irfl460a like snubber etc. It is very important to use the device just as it is in the system with the exact same datashert sink configuration. This test could easily verify Vds and on resistance.

This inspection process may be the most cost effective solution. Dec satasheet2: I know of one company that is taking pictures of the die for incoming inspection by quality control. Lets take that number down to the graph at Figure 4.
