1N5264B is a type of diode of the Zener class which is designed specifically to regulate voltage. Unlike ordinary diodes, Zeners have a special "breakdown voltage" called the Zener voltage which occurs when the junction of the diode is forward biased and the electric current is increased until it reaches a point where the electric field is too high and begins to actively conduct. This conductivity can then be used to stabilize voltage and act as a voltage regulator.

The 1N5264B is a 5.1V Zener diode which can easily be integrated into small and large circuits. It is especially useful in situations where a voltage regulator is needed in a small space and the output power of the circuit needs to be kept stable. It is a single diode, so it only offers unidirectional voltage regulation, meaning that it won’t be suitable for all applications, such as situations where bi-directional voltage regulation is needed.

The 1N5264B Zener diode has a maximum voltage rating of 5.1V, a power dissipation of 200mW and a reverse current of 0.5mA. It is capable of providing a continuous forward current of 5.0mA with a surge capability of 8mA and a surge time of one millisecond. It has a working temperature range of -65 to +150°C, maximum storage temperature of +175°C, clamping voltage of 4.3V, and a Zener impedance of 13.4ohms.

The 1N5264B is a very versatile device, especially in small-scale circuits. They are used most notably in low-voltage power supplies, voltage regulators, voltage references and clipping circuits. For example, in voltage regulators, they can be used to reduce the output voltage of an analog circuit. Similarly, they can be used in an audio circuit to clip the output range of the signal at a certain voltage level. In both of these cases, the Zener diode acts as a form of protection for the circuit and ensures stability of the output.

The working principle of the 1N5264B is similar to that of any other Zener diode. Its ability to regulate voltage comes from the fact that once a certain reverse voltage (the Zener voltage) is applied across its junction, it starts to conduct. This conductivity can then be used to divert current through the Zener, thus creating a stable output. It is important to note, however, that the Zener has a finite and limited current carrying capacity - if the current is too high, then the Zener will be overloaded and it will break down. As such, it is important to select a Zener diode with a sufficient current capacity for the application.

The 1N5264B is one of the most popular Zener diodes on the market due to its wide range of applications in both small and large circuits. It is ideal for use in low-voltage power supplies, voltage regulators, voltage references, and clipping circuits. Furthermore, it has a Zener voltage of 5.1V, a maximum voltage rating of 5.1V, a power dissipation of 200mW and a reverse current of 0.5mA, allowing it to easily offer the required amount of current and voltage regulation in any application.
