Diodes technetium technology allows you one hundred percent satisfaction diode packaging

TVS (TRANSIENT VOLTAGE SUPPRESSOR) or said transient voltage suppression diodes are developed in the regulator process on the basis of a new product, the same as the circuit symbols and ordinary zener diode, the shape is no different from ordinary diodes, TVS tube when both ends subjected to transient high energy impact, it at high speed (up to 1 * 10-12 seconds) so that impedance suddenly reduced, while absorbing a large current, the voltage between both ends of the clamp in a a predetermined value, thereby ensuring back of the circuit elements from transient high-energy impact damage. TVS absolute reaction rate faster than the RC circuit more 10s-12s, can not consider TVS breakdown voltage VBR, reverse threshold voltage VWM, the maximum peak pulse current IPP and a maximum clamping voltage VC and peak pulse power PP. Select VWM equal to or greater than the circuit voltage, VC voltage is less than the value of the protection device can measure the best (IPP), or the estimated pulse power, choose the larger power TVS. Guangdong technetium Electronics Limited production and sales of various type diode twenty years, TVS tube is divided 400W, 600W, 1500W, 3000W, 5000W, can produce different voltage points according to customer requirements, and can be divided into one-way or two-way. Schottky diode structure: new high-voltage Schottky diode structure and materials with traditional Schottky diodes are different. SBD by conventional metal-semiconductor contact with the composition. Optional aluminum metal material, gold, molybdenum, nickel, and titanium, semiconductors typically silicon (Si) or gallium arsenide (GaAs). Since the electron mobility is larger than the hole, in order to obtain good frequency characteristics, so the choice of N-type semiconductor material as the substrate. In order to reduce the SBD junction capacitance and improve the reverse breakdown voltage, so that the series resistance without too large, usually a high resistance N- epitaxial thin layer on the N + substrate. CP is a shell and tube shunt capacitance, LS is the lead inductance, RS is the series resistor comprises a semiconductor body resistance and lead resistance, including, Cj and Rj respectively junction capacitance and junction resistance (both bias, bias function). 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.
