Surge testing apparatus, surge testing method and electronic parts

摘要

PROBLEM TO BE SOLVED: To ensure detecting that specified surge electric power is applied to a test target element.SOLUTION: A surge test apparatus includes: a surge-voltage generation circuit SC applying a surge voltage; a first test terminal T1 connected to an output of the surge-voltage generation circuit SC; a second test terminal T2 that is grounded; a voltage detector VD detecting the surge voltage applied from the surge-voltage generation circuit SC to a test target element connected between the first test terminal T1 and the second test terminal T2 so as to be reversely biased, and having avalanche characteristics; a current detector CD detecting a surge current flowing in the test target element by applying the surge voltage to the test target element from the surge-voltage generation circuit SC; and determination unit JUD determining whether electric power equal to or higher than specified electric power is applied to the test target element on the basis of the detected voltage detected by the voltage detector VD and the detected current detected by the current detector CD.
