Silicon planar power zener diodes are widely used and versatile components in the production and development of electronic circuits. We will dive into the specific characteristics and workplace performance, 1N5733B, which is one type of these planar power zener diodes.

The maximum power dissipation of the 1N5733B is 500mW, which ensures work in a wide range of applications. It adopts a 5.6V peak reverse voltage, which makes it suitable for circuit protection and reference-power supply design. For the reverse leakage current, when the reverse voltages of 1.5V to 5.6V, the reverse voltage decreases exponentially. Nevertheless, the reverse current decreases linearly in low voltage and reaches a value of 4uA at the zener voltage of 4.3V.

The maximum zener impedance of 1N5733B is 75 ohms at the purchased voltage and the maximum working temperature is 150 degrees. In the actual application, the tolerance is 5%. Calculated with JEDEC method, the stored energy is 1.4mJ and the avalanche energy density is 5mJ.

The usual way to use 1N5733B is to connect in series. When the power supply is turned off and the electric current surpasses the rated value of the diode, reverse current will be uniformly discharged from the power supply and will flow from the low voltage end to the high voltage end, that is, from the anode to the cathode.

In addition, 1N5733B uses high-resistivity and low-cost oxide passivation to prevent defect-causing and string leakage, making it widely used in power supplies, audio power amplifiers, television sets, electronic ballast, etc. It also has a great range of practical application, such as a voltage regulator, voltage reference, surge protection device, and the like.

In conclusion, 1N5733B is a high-efficiency, low-cost and wide-range zener diode, suitable for protection and reference-power supply design in commercial applications. With the features of high reverse leakage current and low zener impedance, combined with the 700mW maximum power dissipation, it has up to 5 per cent tolerance and 150 degrees working temperature. Applications of 1N5733B are widely used in power supplies, audio power amplifiers, television sets, electronic ballast, voltage regulator, voltage reference, surge protection device, and related components.
