Diodes are among the most common components in electrical and electronics systems. Zener diodes are specially designed to provide a safe reverse conduction-voltage path over a certain voltage level. Single Zener diodes are a type of Zener diode family, and BZX85C27-TAP is one of them. This application field and working principle of BZX85C27-TAP is elaborated in this paper.

BZX85C27-TAP, with a breakdown voltage of 27V, is a regular current-limiting choice with a power dissipation rating of 500mW. Particularly, it is especially used in relatively low-monitoring voltage application. The voltage coefficient of its breakdown voltage is 2.0mV/°C and its operating temperature is -55°C to 125°C. For its superior features and reliable performance, it is a popular choice for both economic and professional services.

The main application field of BZX85C27-TAP is mainly in portable electronics and computer peripherals. Here, it could be utilized to limit current and minimize the power consumed by the system. It is also adopted in amplifiers, electronic circuits, relays, television receivers, LAN systems and many other industrial and consumer electronic systems.

In addition, many automated systems have integrated BZX85C27-TAP due to its reliable performance in pulse and noise control, high-frequency communications, and AC circuit protection. Similarly, it is used in voltage regulation and overvoltage protection in the power production and distribution systems. Moreover, this diode is also useful in many high-precision control systems due to its low effect of heat on its breakdown voltage.

The working principle of this diode is quite simple as it follows the principle of PN junction diode. It consists of two layers of doped silicon, i.e. two sections of either P-type or N-type silicon. When a forward-biased voltage is applied, a current flow occurs. Contrarily, when a reverse-biased voltage is applied, the PN junction starts to break down and Zener breakdown effect occur, which behaves together with a sudden decrease in the resistance of the diode. This change produces an internally controlled voltage.

Overall, the BZX85C27-TAP is a family of single Zener diodes with a breakdown voltage of 27V and simple PN junction working principle. It is most notably used in portable electronic and computer peripherals. But, due to its exceptional performance and reliable results, it is also useful in a wide range of industrial and consumer electronic systems. Therefore, it is certainly a cost-effective and reliable choice for various application requirements.
