One 、 Background introduction

   I saw the introduction of watermelon in the video a few days ago ,  If you identify the quality of the microwave diode video .  It is impossible to measure the positive conduction of diode directly with Multimeter diode ,  You need to use an electric pen to test .  These are two microwave oven diodes bought from Taobao ,  Now let's check its basic electrical characteristics .

  

Two 、 Basic measurement

   First measure the size of the high voltage diode ,  Its diameter is 7.33mm,  Its length is 21.92mm.  This is a CL01-12 Data manual ,  The nominal size ,  The length of diode is given ,  And the corresponding diameter parameters ,  The result is the same as the measurement .

  

3、 ... and 、 Electrical characteristics

   Now let's use digital adjustable voltage ,  To measure the voltage at both ends of the diode respectively ,  And the voltage on the sampling resistor ,  Thus, the V-A characteristic .  This is a measurement CL01-12 High voltage diode forward V-A Characteristic curve .  It can be seen that its on voltage is above eight volts ,  This makes the ordinary multimeter measure   Its forward conduction characteristic is very difficult .

  
   According to diode CL01-12 Data Book parameters ,  Its reverse internal pressure is as high as 12kV,  According to my current equipment, I can't measure such a high reverse breakdown voltage .
  

Four 、 Internal construction

   Why? CL01-12 Able to withstand high pressure , Why is its forward conduction voltage so high ？  This is related to its special structure ？  Use a hammer to break the epoxy resin package outside the diode .  This is a broken diode .
  
   Next, place them under a magnifying glass for observation .  You can see that it has a multi-layer stacking structure inside .  There is about in all 13 layer ;  If every layer is a diode ,  Then the total diode internal pressure is the sum of all diode withstand voltages .

  
   Use a multimeter to measure CL01-12 Conduction voltage between internal stacking structures . If the direction is not right , The multimeter is not connected . After changing direction , It can measure the forward conduction voltage . The lowest on voltage is 0.7V about . This explanation CL01-12 It is made of multilayer silicon diodes .
