Temperature Derating Method for Safe Operating Area (SOA) |
Generally, voltage, current and power applied to MOSFETs are limited by various conditions, and the limited area is called safe operating area (SOA). Although SOA has temperature dependence, SOA is usually specified at room temperature (25°C), so temperature derating is required when the device temperature rises. This application note describes temperature derating method for SOA. Note that the basic method is the same for bipolar junction transistors (BJTs). |
