Bourns RS-485端口专用气体放电管
Bourns气体放电管(GDT)专用于RS-485端口，设计符合RS-485端口接口的行业标准，并在有噪声的严苛电子环境中提供电路保护。对于不允许发生故障、需应对大电涌和快速电涌的外露线路，建议使用三级Bourns保护系统。该系统包括TVS二极管()、TBU™设备()及一个或多个GDT。每个设备均有其独特的保护功能。根据分层保护计划，TVS阵列由TBU设备充分保护，而TBU设备由快速GDT充分保护。 因此电涌保护的限制即GDT本身的限制。RS-485端口专用Bourns GDT处理极高强度电流并配合TBU设备提供极快的电压保护，以及TBU触发后的过压保护。
It consists of TVS Diodes (CDSOT23-SM712), TBU™ Devices (TBU-CA065-100-WH), and one or more GDTs. Each device contributes a unique protection function. Due to the layered protection scheme, the TVS array is fully protected by the TBU device and the TBU device is fully protected by the fast GDT. The limits of surge protection are then those of the GDT itself. The Bourns GDT for RS-485 Ports handles extremely high currents and coordinates with the TBU device to provide extremely fast voltage protection, as well as protection the TBU device from excessive voltage after it triggers.
