Working Principle of MASMCJ120AE3

TVS or transient voltage suppressor diodes are designed to provide protection from over-voltage and over-current, as well as inductive and capacitive surge protection. The MASMCJ120AE3, specifically, is a FET-equipped diode, which allows it to offer better protection than non-FET diodes.

The working principle of MASMCJ120AE3 is very simple. It basically functions as a switch that is activated when it detects a transient voltage or current that is higher than its operating voltage or current. When activated, the diode conducts current, providing an effective short circuit that dissipates the current, thus protecting the circuit and components.

The diode can handle both AC and DC transients, and its response time is fast enough to protect the circuit from the damage caused by the transient voltage. Furthermore, it is designed to handle multiple current or voltage transients without fail, making it suitable for use in a wide variety of applications.
