Working Principle

In the MMSZ4699ET1, the reverse breakdown voltage is 7.5V when the current flowing through it increases to its maximum limit. When the voltage increases beyond this value, the current will either remain unchanged or slightly reduce. So, when a momentary load is applied, the current can be regulated so that the load does not get overloaded.

The MMSZ4699ET1 has an internal structure which provides very good reverse leakage current characteristics. This characteristic is important in over-voltage protection. When the reverse breakdown voltage is reached, the current can be decreased or limited by the zener action which prevents an overload on the system. Thus, the MMSZ4699ET1 provides an over-voltage protection function when used in conjunction with other components.

The fast switching speed of the MMSZ4699ET1 is ideal for protection circuits of the time varying loads. It is also used in voltage regulator circuits where the input voltage is regulated and an output voltage is generated. The MMSZ4699ET1 can be used as a current limiting device as well. It can offer protection from over-current and short-circuits in applications like consumer electronic products.

In summary, the MMSZ4699ET1 provides good reverse leakage characteristics and can be used for protection from over-voltage, over-current and short-circuits. It is also used in regulator circuits for generating the required voltage. Thanks to its fast switching speed, it is also suitable for protection of time varying loads.
