http://www.eng-tips.com/viewthread.cfm?qid=96155 Ảp THUẬN max mà diode chịu được là như thế nào ? Bt chúng ta đều biết diode có áp ngược chịu được là giới hạn, còn áp thuận có giới hạn không ? (Theo phạm vi thông thường chứ ko phải max như KV). I am having a problem with a 60V Schottky diode. We are having around a 1% failure rate of the diodes in production. This appears to be an early break-in type of failure, since we don't have any failures that show up during life testing. The failure mode is a short. We have not been able to successfully locate the cause of the failure, but have limited it down to 3 causes: overvoltage transient, process damage, or inherent defect. The function of the diode in the circuit is to act as a barrier diode to block reverse voltage. The load is a DC/DC boost converter. After the diode and parallel to the load we have a filter capacitor. The input range of the circuit is 16VDC up to 42VDC. The circ...
