3. Working Principle
The PTVS12VZ1USK315 operates based on the principle of avalanche breakdown. Under normal operating conditions, the TVS diode is in a non - conducting state, similar to an open circuit. The voltage across it is below the reverse stand - off voltage (VRWM). However, when a voltage transient, such as a voltage spike or surge, occurs and the voltage across the diode exceeds the VRWM and reaches the breakdown voltage (VBR), the diode enters the avalanche breakdown region.
In the avalanche breakdown state, a large number of electron - hole pairs are generated within the diode. This causes a significant increase in the current flow through the diode. As a result, the diode starts to conduct and clamps the voltage across the protected circuit to a relatively low and safe level, known as the clamping voltage (VC). The excess energy of the voltage transient is dissipated in the form of heat within the PTVS12VZ1USK315. Once the voltage transient subsides and the voltage across the diode drops below the VBR, the diode returns to its non - conducting state, ready to protect the circuit from any future voltage transients.
