[0033] as Figure 3 、 4 as shown, Figure 3 It is the current curve of the no. 1 resistance R1 = 0.05 ohms, and the third resistance R3 = 4.7K ohms, flowing through diode D2;
[0034] Figure 4 is a voltage waveform diagram of both input and output;
[0035] As can be seen from the above two figures, this application meets the design requirements.
[0036]Working principle: The circuit of the present application is composed of two parts, one is a constant current source, one is a single ordinary TVS diode, the constant current source can suppress the discharge current of the TVS in the range of the TVS tube, set the relevant parameters of the constant current source, you can meet the current value of different TVS, the constant current source is composed of a MOSFET, a small power triode and a regulator, which are very easy to meet the 50V and 100V withstand voltage, but also relatively easy to meet the GJB and related temperature standards, MOSFET selection according to the current...
