Littelfuse产品并非为以下用途而设计,也不应被用于这些用途:包括但不限于汽车、航空航天、医疗、救生、维生、核设施、高可靠性应用、用于手术植入体内的装置,或者在产品故障或运行无法达到理想状态的情况下会造成人身伤害、死亡或财产损失的任何其他应用。除非在适用的Littelfuse产品文档中已有明确说明。 如果将产品用于相关Littelfuse文件中未明确说明的任何其他用途,则产品不享受Littelfuse质保。 如果将产品用于相关Littelfuse文件中未明确说明的其他用途,则Littelfuse不会为因此造成的任何索赔或损失承担责任。 除非经Littelfuse另行许可,否则Littelfuse产品的销售和使用应遵守Littelfuse销售条款与条件。 "Littelfuse"包括Littelfuse, Inc.及其所有附属实体。

SP723采用SCR/二极管两极结构阵列,用于敏感输入电路的ESD和过压保护。 SP723每个输入端都有2个保护SCR/二极管的器件结构。 共有6个有效输入端,可保护高达6条外部信号或总线。 过压保护范围:从IN(引脚1-3和引脚5-7)到V+或V-。

SCR结构适用于+VBE二极管阈值超过V+(引脚8)或-VBE二极管阈值低于V-(引脚4)时需要快速跳闸的场合。 如果瞬态脉冲使输入电压升至V+以上的一个VBE,从输入端IN至V+的箝位电压就会被激活。 如果低于V-的VBE负脉冲施加至IN输入端时,对V-的类似箝位就会被激活,

pdficon ESD and Transient Protection Using the SP720 Application Note

This application note discusses ESD and transient protection using the SP720. For a given level of voltage or power there is a defined degree of protection compatible to that need. For the SP720 the protection circuits are designed to clamp over-voltage within a range of peak current that will substantially improve the survival input expectancy of average monolithic silicon circuits used for small signal and digital processing applications.

pdficon AN9734 IEC Electromagnetic Compatibility Standards for Industrial Process Measurement and Control Equipment

This application note discusses the purpose of the International Electrotechnical Commission lEC 61000-4 (previously known as lEC-801) standard which established a common reference for evaluating the performance of industrial-process measurement and control instrumentation when exposed to electric or electromagnetic interference.

pdficon SP720 SP721 and SP723 Turn-On and Turn-Off Characteristics Application Note

The purpose of this application note is to focus on customer concerns related to the fast switching characteristics of the SP720 SP721 and SP723 family of protection ICs during an ESD discharge. The SCR cell structures of this family were first introduced for ESD protection of sensitive ICs that were subject to substantially more severe conditions than normal Human Body Model stress.
