1 Using MOSFET Safe Operating Area Curves in Your Design

Power MOSFETs are used in applications where voltage and current stresses may exceed their capabilities leading to long term reliability concerns and/or catastrophic failures. This article will review the SOA graph in the MOSFET data sheet and show how it is used to ensure safe operation of the FET in an application without damaging it.
