Pins 11 and 14 are the 2 outputs of the chip. My circuit is 15 volts.

The battery charge may not have intelligent soft start and overstress the charger hooking up to a dead battery. A project I am doing right now needs to switch 60Amps DC. We need to recalculate everything again based on the new info.

You need to know what affect other parameters may have on dstasheet circuit. Nice power supply by the way. Welcome to our site!

If so, can you suggest some part numbers? What are you doing with it?

A bigger switch always puts a bigger Ciss load on the gate. Forums New posts Search forums.

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 RC dynamic losses don’t dominate and exceed conduction losses.

It seems this “entry level” charger” datasheft very little margin before exceeding the component limits. Electrolytic caps are a prime suspect. You haven’t said what how you are using the mosfet, so it’s difficult to accurately answer dagasheet question.

Don’t forget to check the caps.

Ken1 Member Mar 1, The sum of the junction to case and the case to sink resistances is 0. This means that the the junction is. Thread starter Ken1 Start date Feb 28, But if increased current capacity is your only goal, there is a big trap you need to look out for.

I am assuming these are too light for the duty. Irtp450 in a cryogenics lab, but not really a practical value for most real world applications. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. They are mounted on a large aluminum heatsink and the unit also has a cooling fan.

Iirfp450 them a good look, especially those close to the hot heat sink. Datasehet it will only handle 14 amps continuous if the case is kept at 25C all of the time. The unit is relatively new and hasn’t seen much use. So when carrying 14 amps, it will be dissipating about 78 watts of heat.


This is determined by the V-I slope of the driver and RdsOn of the switch. 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.

Let’s look at a few items from the datasheet. I am attempting to repair a Powermax PM power supply unit.

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.

Tc is case temperature, not ambient. Pin 11 which the burned resistor connects to has a very low resistance to ground compared to pin Ken1 Member Feb 28, Misterbenn Active Member Mar 1, One of the pair of Otherwise you’ll need to resort to cold water or refrigerated cooling.

So, at 78 watts, the junction is 69 degrees hotter than the case. Click here to register now. 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. To participate you need to register. I am using four amp mosfets.
