USBQ50424E3/TR7中文资料TVS Array数据手册Microchip规格书

描述 Description

This Transient Voltage Suppressor (TVS) is assembled in a QFN143 package which has the same pinout and footprint as the SOT-143 package. The configuration gives protection to 1 unidirectional data or interface line. It is designed for use in applications where low capacitance protection is required at the board level from voltage transients caused by electrostatic discharge (ESD) as defined in IEC 61000-4-2, electrical fast transients (EFT) per IEC 61000-4-4 and the secondary effects of lightning. These TVS arrays have a peak power rating of 500 watts for an 8/20 ?s pulse (figure 1). With a capacitance of only 3 pF, this part can provide protection to very fast data lines including USB at 900 Mbits/sec.  ROHS, PB Free

简介

USBQ50424E3/TR7属于电路保护的TVS-二极管。由Microchip制造生产的USBQ50424E3/TR7TVS - 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。
