ESD9L5.0ST5G 产品概述

一、产品简介

ESD9L5.0ST5G(品牌:DOWO/东沃)是一款单路、单向低容抗静电与浪涌保护二极管,采用紧凑的 SOD-923 封装,面向高速接口与敏感信号管脚的瞬态过压保护设计。器件兼顾低结电容与高脉冲吸收能力,适合在空间受限且要求高速信号完整性的应用场合使用。

二、主要性能特点

  • 钳位电压(VC):20V(典型条件下@峰值脉冲)
  • 峰值脉冲功率(Ppp):100W @ 8/20μs
  • 峰值脉冲电流(Ipp):4.5A @ 8/20μs
  • 反向静态截止电压(Vrwm):5V,击穿电压(Vbr):6V(象征性阈值)
  • 结电容(Cj):0.5pF,适合高速数据线(如 USB、HDMI、SATA 等)
  • 反向漏电流(Ir):≤1μA
  • 工作温度范围:-55 ℃ ~ +125 ℃
  • 符合 IEC 61000-4-2(静电放电)与 IEC 61000-4-5(浪涌)防护等级

三、电气与环境规格说明

器件以单向 TVS(瞬态电压抑制)形式工作,正常工作电压下反向漏电小于 1μA,可长期并联在线路上。大电流脉冲条件下钳位电压约 20V,Ppp=100W(8/20μs)表示短时浪涌时具有良好的能量吸收能力。超低结电容(0.5pF)有效降低对高速信号的影响,适用于要求高信号完整性的接口保护。

四、封装与物理特性

  • 封装:SOD-923,体积小,便于贴片自动化生产与高密度布板
  • 通道数:单路;极性:单向
  • 推荐布局:靠近被保护引脚放置,走线最短最粗以降低串联电阻与感抗,接地回路要短且低阻抗

五、典型应用场景

  • 移动终端、摄像头模块、高速数据接口(USB、MIPI、LVDS)
  • 工业控制和通信设备的信号线保护
  • 需要同时满足静电放电与雷击浪涌防护的板级保护点

六、选型与使用注意事项

  • 依据系统工作电压选择 Vrwm(本型号 Vrwm=5V,适合 5V 及以下系统保护)
  • 钳位电压随脉冲电流变化,设计时应考虑最大允许电压对下游器件的承受能力
  • 布局时将 TVS 与地线间的回路尽可能短,以提高释放效率并降低感性峰值
  • 高能脉冲多次冲击会引起器件发热或退化,关键场合建议配合熔断器或串联限流元件以提升系统可靠性

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
