MOSFET : The importance of SOA

When a MOSFET is selected for a high power design, engineers often select a device based on its on-resistance. Lower on-resistance results in MOSFETs with lower power loss, which in turn indicates less heating and safer operation for the device. However, a MOSFETs ability to handle a larger current is not based on its on-resistance alone, but also its safer operating area (SOA) capabilities. Join Stein Nesbakk as he explains for which applications SOA is vital, but also how to achieve the balance between low RDS(on) and strong SOA.
