    Abstract: The method of testing a DMOS power transistor (2) comprises the phases of: arranging a switch (4) between the low-voltage circuitry (3) and the gate terminal (G) of the DMOS power transistor (2); maintaining the switch (4) in an open condition; applying a stress voltage to the gate terminal (G); testing the functionality of the DMOS power transistor (2); and, if the test has a positive outcome, short-circuiting the switch (3) through zapping.

    Abstract translation: 测试DMOS功率晶体管(2)的方法包括以下阶段:在低压电路(3)和DMOS功率晶体管(2)的栅极端子(G)之间布置开关(4)。 将开关(4)保持在开启状态; 向栅极端子(G)施加应力电压; 测试DMOS功率晶体管(2)的功能; 并且,如果测试有正面的结果,则通过切换使开关(3)短路。
