However, most of the early types are obsolete, and their nominal daasheet are ‘better’ in that R DS on is lower than the previous version s. The multiplication factor of gives the headroom needed for accurately reproducing a square wave or high frequency sinewavesince the gate driver needs a lot of current to quickly switch the MOSFET from OFF to ON.

What is not commonly noted is that all MOSFET devices have a fairly high negative temperature coefficient for the gate-source threshold voltage V th. It’s worth noting that the TO package is useless regardless of what’s inside for getting rid of any more than about 20W worth of heat, unless extraordinary care is taken with mounting.

STMicroelectronics’ two new microcontroller product lines enhance the energy efficiency, functional integration and design flexibility of the STM32F4 basic product line high-end products to meet the technical requirements of high-performance embedded design. For a better understanding, a simplified output stage circuit is shown below.

Likewise, the peak current should also be much lower than the rated maximum. Accessories for this product. Log in or create an account. This process continues until the cell fails due to over temperature, at which point the MOSFET suffers catastrophic failure.


This is entirely counter-intuitive, and is almost certainly the exact opposite of what you would expect.

The large notch is at the second harmonic, and the small bump to the right is the fourth harmonic. Customers who bought this product also bought: These transistors are controlled by the integrated driver ” LME” with an advanced overload protection system “Soft Clipping”.

Even this will not show the same effects as a true valve amp – the nature of the distortion components will almost certainly be different. This is a minefield, and I suggest that you tread very carefully.

The exact values around the Vbe multiplier also known as a bias servo are critical to ensure that the thermal performance is matched as closely as possible.

Multiplying each figure by five because there are five devices of each polarity gives us 1. Compromise will be almost essential IMO. There’s little or nothing in the datasheets to warn you, and many data sheets even show the SOA for DC. There is no evidence of ‘notch’ distortion or any other datasheer odd harmonic, only a ‘nice’ second harmonic added in. This greatly improved the amplifier.

Don’t add these yet! Lateral MOSFETs as used in P have exactly the same issue, but the curve changes from negative to positive at a much lower current around mAand this is visible on the transfer characteristic graph but you will need to look for it carefully – it is not specified in a useful manner IMO. Well, that is the easy route to take for designing an output stage.


LME Download For the design of the amplifier, I will assume a single LTP input stage. The current to reproduce a sinewave will be a bit lower, since it is a smooth curve, but this much headroom will drastically lower distortion. Note refers to this failure mode as ‘hot-spotting’ or ‘current tunnelling’, but it’s very similar to traditional second breakdown. While this is true to an extent, it is obvious that it is not a general rule upon which one should rely in all circumstances.

What of the second breakdown effect that the manufacturers deny even happens other than in the very fine print? Note that the two curves cross over, but the point where the temperature curves cross is when V GS is at a current of over 40A and the gate-source voltage is 5.

The graph was taken from the IRF data sheet, but has been colour coded to make identification of each graph easier. As it dxtasheet, the design I was looking at was unsuitable for the intended purpose, because the quiescent current needed to remove crossover distortion was too high to be practical.
