Application Notes for Super Junction 190 to 800V Power MOSFETs

Document Title Brief Description
Calculation of Power Dissipation in Switching Circuit This application note describes how to calculate the power dissipation that occurs in a SiC MOSFET in a switching circuit with the SiC MOSFET during switching operations.
Impedance Characteristics of Bypass Capacitor This application note focuses on the impedance characteristics of capacitors, and explains cautions for selecting bypass capacitors.
Importance of Probe Calibration When Measuring Power: Deskew Even when devices used for measurement are calibrated regularly, they will give incorrect results if calibration is not performed for the measurement environment. This application note explains the importance of probe calibration in power measurement environments.
Measurement Method for Phase Margin with Frequency Response Analyzer (FRA) This application note introduces a method for easily measuring the phase margin with a Frequency Response Analyzer (FRA) made by NF Corporation.
Method for Monitoring Switching Waveform This application note explains how to correctly monitor the switching waveforms of the power device element such as switching power supply or a motor drive circuit.
Notes for Temperature Measurement Using Forward Voltage of PN Junction This application note explains cautions regarding the temperature measurement Using Forward Voltage of PN Junction. The content of this application note is generally applicable, irrespective of the types of semiconductor devices.
Notes for Temperature Measurement Using Thermocouples This application note explains cautions regarding the temperature measurement. The content of this application note is generally applicable, irrespective of the types of semiconductor devices.
Precautions When Measuring the Rear of the Package with a Thermocouple This application note describes precautions when measuring the temperature on the rear of a package using a thermocouple to find the junction temperature of a semiconductor chip during actual operation.
Suppression Method of Switching Noise Using Linear Regulator and Low Pass Filter This application note describes the method and result of the ripple and switching noise suppression using a linear regulator and a low pass filter.
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).
Two-Resistor Model for Thermal Simulation This application note explains the two-resistor model, which is the simplest model among thermal models used in thermal simulations. The thermal simulations mentioned here cover three-dimensional model thermal conduction and thermal fluid analysis tools.
What is a Thermal Model - Transistor? Among SPICE models, there are models for performing simulations in relation to heat, which are referred to as thermal models. Simulations using the thermal models are performed to make a rough estimate during the initial stage of thermal design. This application note explains the thermal models.
