The SZMMSZ4711T3G is a single Zener diode capable of operating in the breakdown region and regulating voltage. It has a maximum operating temperature of 125°C and a maximum reverse voltage of 3.3V, as well as a maximum junction temperature of 150°C. It has an average power dissipation of 100mW and a maximum operating current of 100mA. This diode\'s maximum zener impedance at a given current level is 1.5kΩ, and its capacitance at 1MHz is 0.1pF. It also offers an ESD protection of 8KV Human Body Mode.

Application Fields

The SZMMSZ4711T3G can be used in a variety of applications, ranging from voltage regulation in power circuits to ESD protection in sensitive electronics. Its inherent behavior in the breakdown region makes it particularly well-suited for voltage regulation and protection. In power circuits, it can be used to limit voltage, while in digital circuits it can protect transistors, semiconductors, and other components from damage caused by electrostatic discharge. It can also be used in logic, analog, and other circuits where it can be used to control voltage spikes.

Working Principle

The Zener diode operates in a manner known as reverse breakdown. When the voltage exceeds a certain level, known as the Zener voltage, the current begins to increase and acts as a way of regulating voltage. This behavior can be seen as a form of electrostatic discharge protection, as the Zener diode is able to limit the voltage before it reaches a point where it can cause damage. The SZMMSZ4711T3G, in particular, can provide up to 8kV of ESD protection.

Conclusion

The SZMMSZ4711T3G is a single Zener diode with a wide range of applications. Due to its inherent behavior in the breakdown region, it can be used to regulate voltage as well as protect digital and analog circuits from electrostatic discharge. Its maximum reverse voltage of 3.3V, maximum operating temperature of 125°C, and ESD protection of 8KV Human Body Mode make it an ideal choice for a variety of applications. Its ability to limit voltage spikes makes it an especially valuable addition to any power or protection circuit.
