Click here to datasheeet now. Once you have the DC voltage and Current and temperature rise data for a specific heat sink configuration, You can use this configuration to test new parts. As Tony points out, there will usually be some other parameter that changes along the way.

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

IRFPA datasheet, Pinout ,application circuits Power MOSFET

Media New media New comments Search media. Measure Gate charge with a capacitance meter and all that is left is switching speed.

Articles Top Articles Search resources. It seems that you bought some bad parts in that they failed immediately when installed in a plasma display you are working on. This test could easily verify Vds and on resistance. CMOS Technology file 1.

IRFP450 Mosfet Question

So, it will only carry 14 amps if you can keep the case at 25C while it is pushing out 78 watts of heat. That’s way too low as this power supply is powered by VAC which is fed through a bridge rectifier, then filtered with an uF V capacitor then fed to the Mosfets through the SMPS transformer. You need to know what affect other parameters may have on your circuit. There is also a visible crack in the case of the same Mosfet. Not having the correct Torque on the heat sink mounting screw can alter your results.

This is the datasheet I used for this discussion. Maybe a little overkill but, other than the copper plates that carry the current, there is no heatsink. I have heard of counterfeit parts on the market.

Turn on power triac – proposed circuit analysis 0. The top of the package is sanded off exposing the die for inspection under a microscope. Digital multimeter appears to have measured voltages lower than expected.

If the case is at 25C, the junction is at 94C. I am assuming these are too light for the duty.

Ken1 Member Feb 28, Testing all of these could be expensive, but as in the above inspection you may get by with testing 1 or 2 per lot. This inspection process may be the most cost effective solution. The battery charge may not have intelligent soft start and overstress the charger hooking up to a dead battery.

Give them a good look, especially those close to the hot heat sink. Part and Inventory Search.

For this reason I recommend the following: What are you doing with it? Lets take that number down to the graph at Figure 4.

Heat sinks, Part 2: Equating complex number interms of the other 6. One of the pair of datasheett Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. I do not understand the term TR Power.


For example enclosed in a chassis versus external to the chassis. Pins 11 and 14 are the 2 outputs of the chip. How do you get an MCU design to market quickly? Only 1 or 2 parts have to be tested in this way per lot. What is the function of TR1 in this circuit 3. A DC current would then be injected through the device and adjusted to give the same temperature rise on the same heat sink configuration.

Calculate Switching loss Switching loss can be hard to calculate because it is a function of many variables, such as MOSFET parameters, methods of driving switching devices, snubbers, etc. This means that the the junction is. The best way to test a mosfet in circuit 0. Even changing from thermal compound to an insulating thermal pad can alter the thermal resistance enough to invalidate your results.

Otherwise you’ll need to resort to cold water or refrigerated cooling. Input port and input output port declaration in top module 2. But if increased current capacity is your only goal, there is a big trap you need to look out for. Forums New posts Search forums.
