Give them a good look, especially those close to the hot heat sink.
Nice power supply by the way. Click here to register now. 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.
Pin 11 which the datahseet resistor connects to has a very low resistance to ground compared to pin So, it will only carry 14 amps if you can keep the case at 25C while it is pushing out 78 watts of heat. Pins 11 and 14 are the 2 outputs of the chip.

A bigger switch always puts a bigger Ciss load on the gate. Forums New posts Search forums. Thread starter Ken1 Start date Feb 28, This is the datasheet I used for this discussion. Let’s look at datazheet few items from the datasheet.

The sum of the junction to case and the case to sink resistances is 0. To participate you need to register. So, at 78 watts, the junction is 69 degrees hotter than the case. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Lets take that number down to the graph at Figure 4.
Welcome to our site! One of the pair of 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 is at 25C.

Datasheets, Manuals or Parts. This is determined by the V-I slope of the driver and RdsOn of the switch.

If so, can you suggest some part numbers? 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.
This means that the the junction is. 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. As Tony points out, there will usually be some other parameter that changes along datasheeh way. But if increased current capacity is your only goal, there is a big trap you need to look out for.
Take a look at this one. Maybe a little overkill but, other than the copper plates that carry the current, there is no heatsink. Ken1 Member Feb 28, Often the input FETs are just the weak link and something else is the real culprit.
