The KDZTR12B is a single Zener diode designed to regulate a variety of power applications. It is part of the KDZTR series manufactured by Microsemi, a manufacturer of high-reliability semiconductor products. The KDZTR12B is an axial leaded diode with an operating temperature range from -55 to +125 degrees Celsius. The Zener diode has a breakdown voltage of 12 volts.

The KDZTR12B is designed to regulate voltage when applied across a load. It acts as a reverse-biased diode, allowing current to flow in one direction only. When the applied voltage across the diode reaches or exceeds the reverse breakdown voltage, the diode begins to conduct and establishes a constant voltage, regardless of additional changes in the applied voltage. This is known as a clamping action.

The diode\'s behavior can be thought of as a one-way valve, precisely controlling the voltage to the load. It clamps the voltage over and above its breakdown voltage, and eliminates the need for a separate voltage regulator in the circuit.

The KDZTR12B is used in a number of applications, including RF and digital circuit protection, ESD protection, RC snubbing in power supplies, and power lead protection. It is also used in switching power supplies and voltage converters. The diode can also be employed in Class E audio and RF drivers.

The KDZTR12B is part of the KDZTR series of Zener diodes from Microsemi. The series includes diodes with breakdown voltages from 6 to 31 volts, and reverse current ratings from 200 to 600 mA. The series is carefully designed to withstand a wide range of temperatures, and offers reliable, low-cost protection in a variety of applications.
