• As a temperature protection device for integrated circuits.
• For enabling low-noise switching in high-voltage applications.

Working Principle

The MM3Z7V5ST1 Zener diode works by using a Zener breakdown process to allow electrical current to pass through in only one direction. The Zener breakdown process involves a carefully controlled amount of electrical avalanche breakdown in the diode’s electronic structure, allowing a regulated amount of electrical current to flow in only one direction. When the voltage of the power supply is lower than the expected voltage, the diode will pass a current that is proportional to the applied voltage, and thus regulate the voltage output.

As the voltage of the power supply increases above the specified voltage, a small amount of current that is proportional to the applied voltage will pass through the diode, creating a separate current path that is referred to as the Zener breakdown process. This process is what allows the regulated voltage to be output from the diode, without any further regulation from other components of the circuit.

Furthermore, the MM3Z7V5ST1 Zener diode is highly reliable and effective, due to its low thermal impedance, low forward voltage drop, wide operating temperature range, and low leakage current. This makes it ideal for a wide range of applications, such as overvoltage protection, temperature protection, and voltage regulation.
