Choose a new generation technetium Technology Certified 500mW Zener regulator

Schottky diodes principle is a noble metal (gold, silver, aluminum, platinum, etc.) A positive electrode to the negative electrode B is N-type semiconductor, the use of both barrier formed has a contact surface made of a metal rectifying characteristics - the semiconductor device . Because the N-type semiconductor in the presence of a large number of electrons, only a very small amount of the precious metal in free electrons, so the spread to the low concentration of electrons begins A high concentration of B in. Obviously, there is no hole in the metal A, there would be no hole diffusion movement from A to B is. As electrons spreading from B to A, B surface electron concentration gradually decreased, electrically neutral surface is damaged, so they formed a barrier which the electric field direction B → A. However, under the electric field, A electrons will drift motion from A → B, thereby weakening the electric field formed by diffusion movement. After establishing a certain width of space charge region, the electric field induced electron drift motion and different concentrations to achieve a relatively balanced exercise-induced electron diffusion, they formed a Schottky barrier. Technetium Guangdong Electronic Technology Co., Ltd. professional production and sales Schottky diode twenty years, the current is divided into 1A, 2A, 3A, 5A, 8A, 10A, 15A, 20A, 30A, 45A, and it is widely used in various types of power consumer electronics products. Zener diode parameters Iz- rated current refers to the current value of the tube when the tube to generate a stable voltage regulator. Below this value, the regulator, though not impossible regulation, but the stabilizing effect will be worse; Above this value, do not exceed the rated power loss, is also allowed, but regulator performance will be better, but to consume energy. Technetium Guangdong Electronic Technology Co., Ltd. professional production and sales regulator diode twenty years, the majority of customers get the praise.
