High voltage rectifier diode is a kind of energy can be converted to direct current (dc) of semiconductor devices, there is the positive and negative two terminals.High voltage rectifier diode reverse maximum average rectifier, the highest working parameters such as voltage is the users must grasp,Let me give you a little bit of detail to this specific high voltage rectifier diode, hope that can help users better use high voltage rectifier diode products. The main parameters: (1) The maximum average rectifier current IF: refers to the long-term work allows maximum positive average current.The current is determined by the p-n junction area and cooling conditions.Through the diode should be paid attention to when using the average current is not greater than this value, and to meet the cooling conditions. (2) the highest reverse voltage VR refers to exert the maximum allowable on both ends of the diode reverse voltage.If is greater than this value, the reverse surge current (IR), diode unidirectional conductivity was damaged, causing reverse breakdown.Take (VB) half of the reverse breakdown voltage (VR). (3) the largest reverse current IR: it is a diode in the highest reverse voltage, reverse current flow, this parameter to reflect the diode one-way conductive performance is good or bad.So the current value is smaller, which indicates that quality of diode, the better. (4) the breakdown voltage VB: refers to the diode reverse voltage value of volt-ampere characteristic curve bends sharply.Reverse for soft features, meaning is given under the condition of reverse leakage current, voltage value.
