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.

ModelSim – How to force dattasheet struct type written in SystemVerilog? 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.

This is the datasheet I used for this discussion. Not as easy as it sounds. If so, can you suggest some part numbers? How reliable is it?

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 ifp460a at 25C. Doable in a cryogenics lab, but not really a practical value for most real world applications.

But if increased current capacity is your only goal, there is a big trap you need to look out for. Equating complex number interms of the other 6. 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. Often the input FETs are just the weak link and something else is the real culprit.

You haven’t said what how you are using the mosfet, so it’s difficult to accurately datashwet your question.

Dec 248: Pin 11 which the burned resistor connects to has a very low resistance to ground compared to pin I have heard of counterfeit parts on the market. I do not understand the term TR Power. What is the function of TR1 in this circuit 3. Unless all of these factors are considered the calculation is at best a rough approximation.

Maybe a little overkill but, other than the copper plates that carry the current, there is no heatsink.

For example enclosed in a chassis versus external to the chassis. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. The die size of the counterfeit parts is obviously smaller that the real parts.

Hierarchical block is unconnected 3. Dec 242: So, it will only carry 14 amps if you can keep the case at 25C while it is pushing out 78 watts of heat.

A project I am datasueet right now needs to switch 60Amps DC. 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 to the specific heat sink configuration.

As Tony points out, there will usually be some other parameter that changes along the way. Let’s look at a few items from the datasheet. Take a look at this one. 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.

One of the pair of The best way to test datashfet mosfet in circuit 0. 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 Datasueet dynamic losses don’t dominate and exceed conduction losses.

This is determined by the V-I slope of the driver and RdsOn of the switch. Testing all of these could be expensive, but as in the above inspection you may get by with testing 1 or 2 per lot.
