Diodes - Zener - Single

The PZU36B,115 is a single Zener diode, classifying it as part of the Diodes - Zener - Single family. Diodes are two-terminal electrical components with a forward voltage break that allows for current to only flow in one direction. Zener diodes are a variation of a normal diode, with a known breakdown voltage likened to a fixed resistor. A single Zener diode is limited to 5mW of power output and works by dissipating the excess power across the Zener voltage.

The PZU36B,115 is a symmetrical Zener diode, meaning that the forward and reverse breakdown voltages are the same at the same current. It has a Max Power dissipation of 5.0 mW and a Total Capacitance of 4.0 pF. It typically operates at a Forward Voltage of 1.2 V and a Reverse Voltage of 5.5V within a Total Voltage of 6.7V. The minimum breakdown voltage is 4.3V.

The PZU36B,115 can be used in a variety of applications, including:

• Providing overvoltage protection for sensitive electronics
• Overcurrent protection
• Regulating the output of AC-DC converters
• Creating voltage references for op-amps and other application
• Generating constant DC currents

The working principle of the PZU36B,115 is fairly simple. When the voltage across the diode exceeds the breakdown voltage, the diode will “break down,” allowing current to flow across it in both directions and, in the process, dissipate any excess voltage into the Zener voltage.

This process has a number of advantages and disadvantages. For instance, the Zener voltage can be stable between cycles and will self-adjust automatically if the load changes. The PZU36B,115 also protects against overvoltage spikes, which can be extremely damaging. On the downside, however, the diode also limits the input voltage and dissipates power, resulting in power loss. Furthermore, the breakdown voltage of the diode is not always perfectly stable and may drop over time with increasing temperature.

The PZU36B,115 is a versatile and cost-effective solution for a variety of applications that require overvoltage or overcurrent protection, as well as voltage reference generation and DC current generation. By understanding its working principle and its primary applications, engineers can make an informed decision when considering the PZU36B,115 and other similar components for their application.
