LESD8D5.0CAT5G 产品概述

一、产品简介

LESD8D5.0CAT5G 是由 UMW(友台半导体)推出的一款 SOD-882 封装的 ESD 保护器件,专为低电压高速接口提供静电放电(ESD)保护。器件具备低结电容和较高的脉冲承受能力,适合在有限空间内对接口进行防护,同时兼顾信号完整性要求。

二、主要参数与电气特性

  • 反向截止电压(Vrwm):5 V,适配 5 V 及以下工作电压的系统
  • 钳位电压:12.5 V,有效钳止过冲,保护下游电路器件
  • 峰值脉冲电流(Ipp):5.5 A,能承受短时高能量冲击
  • 峰值脉冲功率(Ppp):69 W,用于脉冲能量吸收评估(按厂方脉冲规范)
  • 击穿电压:8 V,在超过 Vrwm 时导通以吸收能量
  • 反向电流(Ir):500 nA,低泄漏电流有利于低功耗系统
  • 结电容(Cj):15 pF,低电容设计对高速信号干扰小
  • 防护等级:符合 IEC 61000-4-2 静电放电防护标准
  • 类型:ESD(瞬态电压抑制)
  • 封装:SOD-882,表面贴装、小尺寸

三、封装与可靠性

SOD-882 小封装利于在紧凑 PCB 布局中靠近信号入口处布置,缩短环路面积以降低寄生电感和干扰。UMW 的生产工艺确保器件在典型环境与快速脉冲条件下具有稳定重复防护能力,适用于消费电子及工业级别的接口防护需求。

四、典型应用场景

  • 以太网、CAT5/5e 等高速网络接口的线路保护
  • USB、HDMI、MIPI、相机接口等高速信号线的 ESD 保护
  • 手机、平板、路由器、交换机、IoT 终端等外部接口防护
  • 工业控制和测控设备的信号输入保护

五、设计与选型建议

  • 将 LESD8D5.0CAT5G 靠近可能遭受静电冲击的连接器或接口走线放置,最小化导线长度与环路面积。
  • 对于对信号完整性要求非常高的差分对,需评估 15 pF 电容对带宽的影响,必要时采用更低电容的保护器件或配合差分滤波设计。
  • 峰值功率与电流为脉冲指标,不宜作为连续工作条件。选型时参考应用的放电能量及脉冲特性。
  • 与地的布线要低阻抗、短回流路径以提高放电能力并减少 EMI 影响。

六、注意事项

器件为瞬态过压防护元件,不作为持续电压或电流承载元件使用。实际系统中应结合 PCB 布局、接地设计及其它保护元件(如串联保护电阻、滤波器)共同实现可靠的防护方案。购买时建议向供应商确认量产一致性及相关曲线(V-I、钳位特性、脉冲寿命)以满足特定应用要求。

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
