Chen表示。“通过在相同的额定电压下实现高达15%的箝位电压降低，我们的折回技术增强了数据中心和工业系统等高可靠性应用的电路保护性能。”5.0SMDJ-FB系列的主要功能与优势包括：•折回技术：可降低箝位电压，提高对电气快速瞬变（EFT）、静电放电（ESD）和其他过压条件的保护；•击穿电压（VBR）始终大于反向断态电压（VR），非常适合保持直流电源线的稳定性；•5000 W的峰值脉冲额定功率，可在恶劣的电气环境中提供强大的保护；•传统5.0SMDJ系列的直接替代产品，具有同样紧凑的DO-214AB（SMC）外形尺寸。这些器件可保护各种要求苛刻的应用中的直流电源线，包括：•以太网供电（PoE）系统；•AI 和数据中心服务器；•ICT设备电源；•工业直流配电。随着系统设计不断发展，包括更高性能、更紧凑的DC/DC转换器，瞬态故障的风险也随之增加。5.0SMDJ-FB系列为设计工程师提供了一种结合了紧凑尺寸、易于集成和先进保护性能的解决方案，以满足这些需求。供货情况5.0SMDJ-FB瞬态抑制二极管提供卷带封装，起订量3,000只。通过全球授权的Littelfuse经销商接受样品请求。如需了解Littelfuse授权经销商名单，请访问Littelfuse.com。更多信息可通过以下方式查看更多信息：5.0SMDJ-FB系列产品页面.如有技术问题，请联系：ESBU产品营销总监Ben
