A project I am doing right now needs to switch 60Amps DC. Heat sinks, Part 2: How do you get an MCU design to market quickly? So, if you’re looking for a mosfet to continuously carry 20 amps, you will probably need a mosfet s with current capacity 3 to 10 times 20 amps.

IRFPA – IRFPA part cross-reference datasheet –

PV charger battery circuit 4. Replacement Transformer Started by ncag 55 minutes ago Replies: Give them a good look, especially those close to the hot heat sink.

Only 1 or 2 parts have to be tested in this way per lot. This actual working model must contain the actual drive circuitry and heat sink as well as any other associated circuits like snubber etc.


Irfp460w if increased current capacity is your only goal, there is a big trap you need to look out for. PNP transistor not working 2.


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. You need to know what affect other parameters may have on your circuit.

What is the function of TR1 in this circuit 3. If so, can you suggest some part numbers?

It seems this “entry level” charger” has very little margin before exceeding the component limits. This inspection process may be the most cost effective solution.

AF modulator in Transmitter what is the A? The unit belongs to a neighbour and he said it just quit working; he doesn’t know if it was running hot before it quit. So, at 78 watts, the junction is 69 degrees hotter than the case. I know of one company that is taking pictures of the die for incoming inspection by quality control. For this reason I recommend the irfl460a You would like to verify component parameters by test before installing to avoid damage to the unit when the component fails.

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. If the case is at 25C, the junction is at 94C.

Ken1 Member Mar 1, There is also a visible crack in the case of the same Mosfet. CMOS Technology file 1. So, it will only carry 14 amps if you can keep the case at 25C while it is pushing out 78 watts of heat. The unit is relatively new and hasn’t seen much use.

The die size of the counterfeit parts is obviously smaller that the real parts. Articles Top Articles Search resources. This is determined by the V-I slope of the driver and RdsOn of the switch.

If you use a different heat sink or different airflow it will invalidate the results. Tc is case temperature, not ambient. Even changing from thermal compound to an insulating thermal pad can alter the thermal resistance enough to invalidate your results.

Dataheet seems that you bought some bad parts in that they failed immediately when installed in a plasma display you are working on. What xatasheet you doing with it? Click here to register now.
