TDZ2V7J, 115 is a single breakdown Zener diode with a maximum reverse voltage of 115 volts. This voltage is chosen to provide protection from high voltage events in a wide variety of applications. The rated current of the device is 400 mA and its power rating is 1/8 watt. The peak forward current for a pulse is 3 amps. It also has a low forward voltage drop of 0.7V at 1A allowing for efficient switching in many circuits. This diode is available in a variety of packages.

A Zener diode acts as a voltage regulator, limiting the voltage to the value stated in its datasheet. It is connected so that the anode is connected to the positive voltage supply and the cathode is connected to the load. This configuration allows the diode to easily pass current from the supply source to the load. However, when the voltage across the reverse biased junction exceeds the Zener voltage a voltage breakdown occurs, allowing the current to flow from the cathode to the anode and aiding the Zener diode to regulate the voltage.

This Zener diode can be used in a wide range of applications such as industrial controllers, power supplies, lighting control, electrical safety areas, protection of transistors, circuit breakdown prevention and protection against voltage surges. These diodes are also used in clamping circuits, such as those used in television and radio receivers, to ensure that the voltage across active components such as transistors never exceed the peak voltage available in the circuit.

This Zener diode is also used in biasing circuits. In this application, it provides stable voltage to an active device like a transistor. The Zener diode is connected in parallel to the transistor collector and creates a voltage drop of the Zener voltage across it, allowing the transistor to be biased to the correct voltage. This type of circuit is used to create stable amplifier circuits, as well as to provide low distortion when amplifying audio signals.

A Zener diode’s working principle is based on the principle of Zener Breakdown Voltage. This phenomenon occurs due to the concentration of electric field at the junctions of a p-n junction diode. When the reverse voltage across the diode exceeds the breakdown voltage, the electric field intensity at the junction increases significantly. This field causes electrons to jump across the junction, and they move towards the anode. As a result, the diode becomes conductive in the reverse direction and creates a path for current to flow which in turn regulates the voltage.

Overall, the TDZ2V7J, 115 is a widely used Zener diode that offers a wide range of applications and provides excellent performance in voltage regulating and surge protection. With its low forward voltage drop, efficient switching and wide range of packages available, it is the perfect choice for many applications.
