Diodes are important non-linear semiconductor components that have a wide range of uses in all sorts of electrical systems. Zener diodes are a special type of diode that display the Zener effect, which allows the diode to efficiently regulate the voltage across a circuit. single zener diodes are designed for single DC voltage regulation, and the TZX11D-TR is a popular device for this purpose.

Application Field

The TZX11D-TR has a maximum blocking voltage of 23V, a maximum zener voltage of 11V, and a maximum power dissipation of 350mW in an SOT-323 package. These characteristics make it suitable for use in a wide range of AC/DC and DC/DC applications, such as automotive electronics, computer peripherals, mobile phones and communications systems, and more.

The TZX11D-TR is ideal for applications that require tight voltage regulation in environments with high noise levels and high temperature variability. The device is ideal for use in high efficiency switching power supplies, as its low temperature coefficient helps to guarantee reliable and stable performance in variable power systems.

Working Principle

The TZX11D-TR is a zener diode designed for single DC voltage regulation. It utilizes the Zener effect, which is when a volt-ampere (V-A) curve displays the diode\'s capability to regulate the voltage output of the circuit.

The TZX11D-TR utilizes a unique combination of semiconductor materials to create a PN junction diode with a Zener breakdown voltage within the value range specified. This voltage is determined by the amounts of materials used and the doping concentrations. The voltage drop across the diode is relatively constant over the entire operating temperature range, thus allowing for tighter voltage regulation.

The voltage is regulated by the built-in resistance in the PN junction. When the voltage across the diode exceeds the Zener breakdown voltage, the PN junction resistance increases dramatically, making the diode act as a voltage regulator. This ensures that the applied voltage remains within the specified value range, regardless of load or temperature fluctuations.

The TZX11D-TR is designed for use in applications where the supply voltage is greater than the zener breakdown voltage, and the current is a constant or varying AC/DC source. This allows the device to be used in any AC/DC powered system. It also features reverse voltage protection, overvoltage protection and ESD protection, to ensure stable performance in any application.
