浪涌防护装置及方法以及一种移动终端
摘要：
本公开是关于一种浪涌防护装置及方法以及一种移动终端，涉及电子领域，该装置包括瞬态抑制二极管和过压保护芯片，其中，所述瞬态抑制二极管的一端连接于所述过压保护芯片与需进行浪涌防护的接口的公共端上，所述瞬态抑制二极管的另一端接地，所述过压保护芯片的另一端与需进行浪涌防护的芯片连接。通过利用瞬态抑制二极管和过压保护芯片对可能发生的浪涌进行双重保护，降低了对瞬态抑制二极管的高防护能力的要求，降低了瞬态抑制二极管的制作难度和成本，从而减小了瞬态抑制二极管的体积，减轻了需进行浪涌防护的芯片的电路板的空间负担，且提高了浪涌防护的效果。
摘要（英）：

The invention discloses a surge protection device and method and a mobile terminal, and relates to the field of the electronics. The device comprises a transient voltage suppression diode and an overvoltage protection chip, wherein one end of the transient voltage suppression diode is connected with a common port of the overvoltage protection chip and an interface needing the surge protection, and the other end of the transient voltage suppression diode is grounded; the other end of the overvoltage protection chip is connected with a chip needing the surge protection. The transient voltage suppression diode and the overvoltage protection chip are used for performing dual protection on the possible surge, the high-protection capability requirement on the transient voltage suppression diode is lowered, the manufacturing difficulty and cost of the transient voltage suppression diode is lowered, so that the volume of the transient voltage suppression diode is reduced, the space burden of the a circuit board of the chip needing the surge protection is relieved, and the surge protection effect is improved.
