V47ZC7PX2855 TVS - Varistors, MOVs Application Field and Working Principle

TVS (Transient Voltage Suppressor), Varistor (Voltage Dependent Resistor), MOV (Metal Oxide Varistor) are all three-terminal components which perform the same function: to protect other electronic components from over-voltage. The V47ZC7PX2855 belongs to the TVS family and is specifically designed to protect sensitive electronic circuits from transient over-voltage conditions.

Principle of Operation

TVS, Varistor and MOV devices are all based on the same basic principle: when a device is stressed with an electrical signal beyond its absolute maximum voltage rating, it dissipates the excess energy as heat; thereby protecting the components connected to it. In the case of a V47ZC7PX2855 this is achieved by a P-N junction diode placed between one terminal and the other two.When the protection device is triggered, it immediately goes into reverse polarization, creating a low impedance shunt path. This ensures that any voltages above the absolute maximum rating of the V47ZC7PX2855 are shunted safely away from the other components.
