Each has its own strengths and weaknesses which forces us to choose between them. First name is required! The article is intended to describe the design process and how to work around the inherent non-linearity of vertical MOSFETs, and is not intended to be a construction project.

Mitch has dxtasheet a compelling case, but much has changed since the article was written, and there is also more information available. Reducing the gate resistors to 4. Also take note that HEXFETs will require a Vbe multiplier for thermal compensation, since the negative temperature coefficient does not come into play until the device has about 10 amps through it at least for the IRFP Quickly Enter the access of compare list to find replaceable electronic parts.
This process continues until the cell fails due to over temperature, at which point the MOSFET suffers catastrophic failure. While it worked well enough, giving the expected power output and with fairly low distortion, as noted above the required bias current is quite high to reduce crossover distortion to an acceptable figure.

The multiplication factor of gives the headroom needed for accurately reproducing a square wave or high frequency sinewavesince the gate driver needs datasueet lot of current to quickly switch the MOSFET from OFF to ON. This may include adding a class AB driver stage. The modularity and ease of implementation makes it a reference choice for any dual mono stereo DIY amplifier project or the realization of multichannel amplifiers.

See the IR application note for more detailed information [ 4 ]. Figure 6 – Normalised V th Vs. Using just a pot as shown in P is absolutely forbidden with vertical FETs – a matched bias servo thermally coupled to the MOSFET heatsink is essential to prevent both thermal runaway and crossover distortion.
Likewise, the peak current should also be much lower than the rated maximum. However, most of the early types are obsolete, and their nominal replacements are ‘better’ in that R DS on is lower than the previous version s. Specifications Contact Us Ordering Guides.
The test I ran was very simple. Lateral MOSFETs datasheef 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.

You already have posted a review for this order. These devices are extremely rugged, yet they do dataxheet a large nonlinear gate capacitance to deal with.

R DS on is actually meaningless in a linear application until the amp starts to clip, and even dafasheet only reduces the maximum output power slightly. You can also merge the voltage supply level and the current level, the freedom to choose.
It is definitely not insignificant for a linear circuit as shown in Figure 4and especially so because of the relatively high transconductance of vertical MOSFETs.
You are welcome to visit us for culture exchange and mutrual business development and progress. There is also the possibility of a failure mode very similar to second breakdown when HEXFETs used in linear circuits, where V GS is usually well below the inflection point.
As the picture shows, the second harmonic was reduced considerably, while the fourth harmonic is below the noise floor. Register Log in Shopping cart 0 You have no items in your shopping cart.
However, the two are directly related, so the point is moot. It is claimed to be ‘insignificant’, and for switching applications this is true. This does not mean use an inadequate datashest, but the bias between devices should be a bit more than many are used to. No products To be determined Shipping.
