Being part of the Diodes – Zener – Single category, the KDZTR18B model is a two-lead single-order Zener diode. It features a low reverse blocking voltage drop in the range of 1.0 Volts to 18 Volts with a relatively large current capability. It can also handle a maximum DC power dissipation of 600 mW at a junction temperature of 25 °C.

KDZTR18B has numerous applications. It is utilized in many everyday electronics and computers as a form of protection against electrical shorts within a circuit. It is also widely used to maintain a constant voltage level in various machines because of its low reverse breakdown voltage. KDZTR18B is a part of numerous linear voltage regulator circuits, inverters, motor controllers, UPS systems and in other industrial applications.

The working principle of KDZTR18B is quite simple. In cases where input voltage exceeds the level set by the voltage regulator, the KDZTR18B utilizes its breakdown voltage to divert the excess current and protect the regulator from overload. This type of protection is known as over-voltage protection. KDZTR18B also works similarly in a case of a low voltage drop, but instead of diverting the excess current it sources the current from itself and maintains the regulation of the voltage from its breakdown voltage.

KDZTR18B uses its Zener diode structure to produce a tailored breakdown voltage from heavily doped PN-junctions. That breakdown voltage created by the machine produces a strong flow of current in the reverse direction. That current is clamped to the voltage of the Zener diode and remains constant at this value regardless of the variations of the external voltage.

To use KDZTR18B correctly in circuit boards is an essential point of consideration. Improper usage of the diode, as well as varying conditions such as temperature, may lead to malfunctioning or even possibly damage of the diode. It is important to use the diode is a proper current regime to avoid overloading it, or in cases of voltage fluctuations apply resistors next to the diode to shape the current and avoid harming the device.

Being part of the Diodes - Zener - Single family, the KDZTR18B model offers reliable protection and regulated levels of voltage and current. It has many possible uses and, when used correctly, it provides a valuable service in many industrial, computer and everyday electronics applications.
