The method of measuring fast recovery and ultrafast recovery diode with multimeter is basically the same as the method of detecting plastic sealed silicon rectifier diode. ...
Schottky diode is a low-power, high-current,ultra-high-speed semiconductor device, reverse recovery time trr can be small to a few nanoseconds ...
Distinguish polarity to place the multimeter in RX1kQ block,and the black stylus arbitrarily connect a pin of the whole bridge component,and measure the other three pins with the red stylus,if the measured resistance is infinite ...
Diodes are generally not good repair, damage can only be replaced. In selecting diodes, we should pay attention to the following principles. ...
Intuitive judgment. Some of the circuit symbols are printed on the diode to indicate polarity; one end of the negative pole of the diode is printed with a color ring as a negative mark ...
