Diodes are one of the most widely used semiconductor components, playing a very important role in many fields. Among them, Zener diode is a special semiconductor component. Single Zener diode means that there is only one PN junction in it. SMBG5343BE3/TR13 is a commonly used single Zener diode. It is featured by low leakage current and low tolerance. This article will discuss the application field and working principle of SMBG5343BE3/TR13 in detail.

Different Zener diodes have different application fields due to different physical parameters. SMBG5343BE3/TR13 is mainly used in the field of constant voltage circuit and voltage stabilization circuit. For example, in power supply circuit, SMBG5343BE3/TR13 can be used to stabilize the output voltage in a precise range, providing a steady power to the connected circuit, thus regulating the entire circuit. In communications system, SMBG5343BE3/TR13 can be used as voltage suppression and noise filtering, ensuring a precise and steady signal transmission.

The working principle of SMBG5343BE3/TR13 is based on the Zener effect. The PN junction of Zener diode has the characteristics that when a reverse voltage is applied to the diode, the leakage current will increase exponentially. Generally, when the reverse bias voltage of the diode exceeds the Zener voltage of the diode, the Zener effect will occur. In this way, the leakage current begins to increase exponentially, and the diode can obtain a relatively stable and precise reverse voltage, and the voltage value is equal to the Zener voltage.

In addition, the reverse bias voltage of SMBG5343BE3/TR13 is 5.3V, and the stability service temperature range is -30℃ to 125℃. The maximum continuous leakage current is 0.5 mA, the reverse current is 0.1 mA, and the breakdown voltage accuracy is ±2%. Its noise immunity is excellent. The SMBG5343BE3/TR13 chip size is 0805, and its lead welding temperature is as low as 260℃.
