Selecting tvs diode
WebTVS P Z V Z Zener Diode TVS Figure 5: Zener and TVS I-V characteristics compared Although they appear similar, a closer look at the I-V characteristics in Figure 5 immediately shows the differences. The Zener Diode (blue trace, Vz) has a much sharper knee, steeper slope and tighter voltage tolerance (dashed lines and shaded region) than a TVS ... WebA PROTECTION DIODE HAS TO BE INVISIBLE Within the normal working voltage range of an application, an ESD or TVS diode has to be “invisible” for the application. The normal performance should not be influenced by the presence of a protection diode in a circuit. Therefore the leakage current and the capacitance have to be low enough.

WebApr 21, 2024 · For the voltage rating of the TVS, you need to make sure that it is comfortably above the maximum supply voltage. Note that the circuit that drives the coil will see the sum of the clamping voltage and your supply voltage, which would be 24 + 77 = 101 V with the P6KE62CA.

The energy absorbed by a TVS can be derived by integrating power with time as follows: Equation 3: where the power P(t) is a function of time t as primarily dictated by pulse wave shape of surge current, multiplied by the clamping voltage VC. For a TVS clamp characteristic, the latter VC is often considered
