用于机动车和通信系统收发器接口的设备
摘要：
本公开涉及用于机动车和通信系统收发器接口的设备。通信接口保护装置包括：电连接到第一端子的第一电气过应力(EOS)保护开关和电连接到第二端子的第二EOS保护开关。第一和第二EOS保护开关中的每一个包括第一半导体控制的整流器(SCR)和第二SCR以及阴极电连接到所述第一SCR的阳极的第一二极管和阴极电连接到所述第二SCR的阳极的第二二极管，所述第一EOS保护装置被配置为响应于在所述第一和第二端子之间引起第一偏置的EOS条件而激活，并且其中所述第二EOS保护装置被配置为响应于在所述第一和第二端子之间引起第二偏置的EOS条件而激活。
摘要（英）：

A communication interface protection device includes a first electrical overstress (EOS) protection switch electrically connected to a first terminal and a second EOS protection switch electrically connected to a second terminal. Each of the first and second EOS protection switches includes a first semiconductor-controlled rectifier (SCR) and a second SCR and a first diode having a cathode electrically connected to an anode of the first SCR and a second diode having a cathode electrically connected to an anode of the second SCR. The first EOS protection device is configured to be activated in response to an EOS condition that causes a first bias between the first and second terminals, and wherein the second EOS protection device is configured to be activated in response to an EOS condition that causes a second bias between the first and second terminals.
