Diode reverse recovery current dissipation is the most important source of power dissipation for diodes used in fast switching converters or other power devices applications. As the reverse recovery current can peak at very high currents, this may cause the failures of other devices in the circuit. Therefore the Diode Reverse Recovery phenomena should no longer be ignored in device model and circuit simulations employing diodes. Automatic measurement of Diode Reverse Recovery time is becoming essential for mass production industrial process monitoring and device modeling. In this paper, a novel Sagittarius automatic Diode Reverse Recovery Time Measurement System was developed. This system has enabled the automation measurement and improved the measurement speed for about 5-7 times. A new Verilog A Diode Reverse Recovery model which can reflect the actual device characteristics was developed base on the data measured using this new system.
