Understanding MOSFET data sheets

We have developed a six-part technical article series that discusses some of the fundamental parts of a MOSFET datasheet. Prefer watching a video? We also created accompanying videos for this series. 

UIS/avalanche ratings Learn how to interpret UIS/avalanche ratings on a MOSFET data sheet. Watch video
Safe operating area (SOA) graph Learn how to interpret SOA curves on a MOSFET data sheet. Watch video
Continuous current ratings Learn how MOSFET current ratings are not measured the way that parameters like RDS(ON) and gate charge are determined, but rather, they are calculated, and can be arrived at in many different ways. Watch video
Pulsed current ratings Learn how pulsed current ratings are calculated and how they are represented in the safe operating area graph on the FET data sheet. -
Switching parameters Learn about other miscellaneous switching parameters that appear in the MOSFET data sheet their relevance (or lack thereof) to overall device performance. Watch video
Thermal impedance Learn about the junction-to-ambient thermal impedance and junction-to-case thermal impedance parameters on a FET data sheet.  Watch video
