Utilising power MOSFET Zth curves
Keywords:power semiconductors? pulse mode? junction temperatures? waveforms?
Most applications which include power semiconductors usually involve some form of pulse mode operation. This paper gives several worked examples showing how junction temperatures can be simply calculated using the device Zth curves. Examples are given for a variety of waveforms:
???Single shot rectangular pulse
???Composite waveforms
???A pulse burst
???Non-rectangular pulses
???Single shot rectangular pulse
???Composite waveforms
???A pulse burst
???Non-rectangular pulses
Throughout this document we will use the SOT404 BUK961R6-40E device as an example.
