USB6B1RL电路保护的TVS-二极管规格书PDF中文资料

USB6B1RL属于电路保护的TVS-二极管。由意法半导体集团制造生产的USB6B1RLTVS - 二极管TVS 二极管是一种半导体器件，可用于限制或阻止特定电压电平的浪涌。该系列产品使用二极管（只能单向导电的元器件）进行设计。TVS 是 Transient Voltage Suppression/Suppressor（瞬态电压抑制/抑制器）的首字母缩写。类型包括转向（轨至轨）或齐纳，具有单向通道、双向通道、电压 – 反关态、电压 – 击穿、电压 – 箝位、电流 – 峰值脉冲、功率 – 峰值脉冲和电源线路保护等特征。

DESCRIPTION

In order to prevent fast transients from leading to severe damages in a high speed data system, a specific protection has been developed by STMicroelectronics.

The USB6Bx protects the two input lines against overvoltage. Besides, this device also keeps the power rails in a safe limit thanks to the integrated Transil diode.

FEATURES

◾ Full diode bridge with integrated clamping protection

◾ Breakdown voltage : VBR = 6V min.

◾ Peak pulse power dissipation : PPP = 500W(8/20µs)

◾ Very low capacitance, compatible with high debit data or signal rates.

APPLICATIONS

Where transient overvoltage protection in sensitive equipment is required, such as:

- Universal Serial Bus ports

- RS-423 interfaces

- RS-485 interfaces

- ISDN equipment

- T1/E1 line cards

- HDSL / ASDL interfaces

BENEFITS

◾ Provides protection for each line and between the supply voltage and GND : 25A , 8/20µs.

◾ High ESD protection level : up to level 3 per MIL STD 883C-Method 3015-6

◾ Separated inputs and outputs (so-called 4-point structure) to improve ESD susceptibility.

◾ Comprehensive package pin-out for immediate implementation.
