5V 双向TVS管X*D5VD923B/*D9B5，单价：0.072元

概述：
   The X*D5VD923B *D protector is designed to replace multilayer varistors (MLVs) in portable applications such as cell phones, notebook computers, and PDA’s. They feature large cross-sectional area junctions for conducting high transient currents, offer desirable electrical characteristics for board level protection, such as fast response time, lower operating voltage, lower clamping voltage and no device degradation when compared to MLVs. The X*D5VD923Bprotects sensitive semiconductor components from damage or upset due to electrostatic discharge (*D) and other voltage induced transient events. The  is available in a SOD-923 X*D5VD923B package with working voltages of 5 volt. It gives designer the flexibility to protect one bidirectional line in applications where arrays are not practical. Additionally, it may be “sprinkled” around the board in applications where board space is  at a premium. It may be used to meet the *D immunity requirements of IEC 61000-4-2, Level 4 (&plu*n;15kV air, &plu*n;8kV contact discharge)
