The SMPZ3920B-E3/85A is a single zener diode that has a wide range of applications. It is the industry leader for low voltage drop, voltage stability, and service lifetime. This diode is commonly used in voltage regulation, overvoltage protection, and reverse polarity protection. This article will discuss the application field and working principle of the SMPZ3920B-E3/85A.The SMPZ3920B-E3/85A has a wide range of applications and is suitable for use in high-frequency circuits, television receivers, and video games. It can also be used in power supplies, LCD power supplies, high switching speed circuits, voltage regulators, and high-frequency systems. This diode has high speed operation with a low tolerance of 1.0% and a low voltage drop of 0.37V at 5mA. It has a low on-state resistance of 3Ω.The SMPZ3920B-E3/85A is a single zener diode that works on the principle of suppressing voltage in a circuit. This diode is constructed from two sections, one anode and one cathode. The cathode is connected to the voltage source and the anode is connected to the load. When the voltage of the voltage source is greater than the breakdown voltage of the diode, the diode will conduct and allow current to flow from the anode to the cathode. This causes the voltage of the load to be reduced, and the voltage across the diode to rise. The diode will then begin to conduct more current, thus increasing the voltage drop across the diode.The SMPZ3920B-E3/85A is an ideal choice for voltage regulation. It has the ability to sense and stabilize output voltage, making it a highly reliable regulator. In addition, its low on-state resistance allow it to maintain a very low quiescent current in standby mode. This, in turn, reduces power consumption and significantly improves the system\'s efficiency.The SMPZ3920B-E3/85A is also suitable for use in overvoltage protection. It can be used in a circuit to limit the voltage from the voltage source, thereby preventing damage from occurring from overvoltage. This diode can also be used for reverse polarity protection. This means that if the polarity of the voltage source is reversed, then the diode will block current flow and protect the circuit from damage.In conclusion, the SMPZ3920B-E3/85A is a single zener diode that is commonly used for voltage regulation, overvoltage protection and reverse polarity protection. It has a low tolerance of 1.0% and a low voltage drop of 0.37V at 5mA, making it ideal for use in high-frequency circuits and voltage regulators. Its low on-state resistance allows it to maintain a low quiescent current in standby mode, which reduces power consumption and improves system efficiency.
