Understanding the Data Sheet: PowerMOS:Allmanufacturers of powerMOSFETs provide a data sheet
for every type produced. The purpose of the data sheet is
primarily to give an indication as to the capabilities of a
particular product. It is also useful for the purpose of
selecting device equivalents between different
manufacturers. In some cases however data on a number
of parameters may be quoted under subtly different
conditions by different manufacturers, particularly on
second order parameters such as switching times. In
addition the information contained within the data sheet
does not always appear relevant for the application. Using
data sheets and selecting device equivalents therefore
requires caution and an understanding of exactly what the
data means and how it can be interpreted. Throughout this
chapter the BUK553-100A is used as an example, this
device is a 100 V logic level MOSFET.
