说明：  在汽车电子的驱动负载的各种应用中,最常见的半导体元件就是功率MOSFET 了。本文 不准备写成一篇介绍功率MOSFET 的技术大全,只是让读者去了解如何正确的理解功率 MOSFET 数据表中的常用主要参数,以帮助设计者更好的使用功率MOSFET 进行设计。 数据表中的参数分为两类:即最大额定值和电气特性值。对于前者,在任何情况下都不能 超过,否则器件将永久损害 对于后者,一般以最小值、最大值、和典型值的形式给出，它们的 值与测试方法和应用条件密切相关。在实际应用中，若超出电气特性值，器件本身并不一定 损坏，但如果设计裕度不足，可能导致电路工作失常
(In a variety of applications in the automotive electronics to drive the load, the most common semiconductor element is a power MOSFET. This article Not ready to write a description of the power MOSFET technology Daquan, just let the reader to understand how to properly understand the power MOSFET data sheet main parameters commonly used to help designers make better use of the power MOSFET design. Data sheet parameters are divided into two categories: the maximum ratings and electrical characteristics values. For the former, can not under any circumstances Over, otherwise the device will permanently damage for the latter, generally the minimum, maximum, and typical values are given in the form of their Closely related to the value of the test methods and application conditions. In practice, if the value exceeds the electrical characteristics of the device itself is not necessarily Damage, but if the design margin, this could lead to circuit malfunction)
