Set the multimeter to the R × 1k position and measure the forward and reverse resistance between A-GA, GA-GK, and GK - respectively.
The average rated on state current IT is the average value of a 50 Hz sine half wave current that can continuously pass between the anode and cathode under certain conditions.
Repetitive peak voltage in both forward and reverse directions - rated voltage (VDRM, VRRM, whichever is smaller).
1. Power supply circuit; 2. Amplification circuit debugging; 3. Machine tone tuning; 4. The heat dissipation of the machine and the fixation of the power pipe
For the safe use of field-effect transistors, the maximum dissipation power, maximum drain source voltage, maximum gate source voltage, and maximum current of the transistor should not be exceeded in the design of the circuit.
1. Determine gate G, 2. Determine source S and drain D, 3. Measure drain source on state resistance RDS (on), 4. Check transconductance
