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.
