ESD3Z5.0C 产品概述

ESD3Z5.0C是KUU品牌推出的一款单路双向ESD防护器件,专为敏感电子电路的瞬态过压防护设计,具备宽温适应性、低电容、高脉冲耐受等核心优势,广泛适配消费电子、汽车电子、工业控制等多领域应用。

一、核心参数总览

该器件的关键参数围绕瞬态干扰抑制的核心需求设计,具体如下:

  • 极性:双向,无需区分正负极,可同时防护正负向瞬态脉冲;
  • 反向截止电压(Vrwm):5V,正常工作时可承受的最大反向电压,不影响电路信号传输;
  • 击穿电压:典型值7.8V,最小值5.6V,确保瞬态干扰触发时快速导通;
  • 钳位电压:16V,干扰峰值时的电压限制值,有效保护后级电路;
  • 峰值脉冲电流(Ipp):8A(tp=8/20μs),可承受的标准脉冲电流上限;
  • 峰值脉冲功率(Ppp):100W,对应脉冲能量的耐受能力;
  • 结电容(Cj):10pF,低电容特性对高频信号损耗极小;
  • 工作温度范围:-40℃~+150℃,覆盖宽温环境需求;
  • 通道数:单路,适配单路信号接口防护;
  • 反向漏电流(Ir):1μA(@Vrwm=5V),低漏电流降低功耗损耗。

二、关键特性解析

ESD3Z5.0C的性能优势可从以下维度体现:

  1. 双向防护简化设计:无需区分引脚极性,电路布局灵活,可同时抑制正负向静电放电(ESD)、电快速瞬变脉冲群(EFT)等干扰,提升系统可靠性;
  2. 低电容适配高速信号:10pF的结电容对USB 2.0/3.0、HDMI、以太网等高速信号的传输损耗可忽略,不影响信号完整性;
  3. 高脉冲耐受能力:8A的峰值脉冲电流(符合8/20μs标准波形)及100W峰值功率,可应对接触放电±8kV、空气放电±15kV的静电冲击;
  4. 宽温稳定工作:-40℃至+150℃的工作温度范围,满足工业现场、车载高温区域等 harsh环境的长期使用;
  5. 国际标准认证:符合IEC 61000-4-2(ESD)、IEC 61000-4-4(EFT)测试规范,防护性能经权威验证;
  6. 小封装高密度集成:SOD-323封装(尺寸约1.6mm×0.8mm),体积小巧,适合智能手机、智能穿戴等高密度PCB设计场景。

三、典型应用场景

该器件的参数特性使其适配多领域的信号接口防护,常见应用包括:

  1. 消费电子:智能手机、平板电脑、智能手表的USB接口、音频接口、HDMI接口防护,避免用户操作时的静电损坏;
  2. 汽车电子:车载信息娱乐系统的USB、蓝牙接口,传感器(温度、压力)信号接口的瞬态干扰防护,适应车载宽温环境;
  3. 工业控制:PLC控制器的RS485、以太网接口,现场传感器的输入输出接口防护,应对工业现场电磁干扰;
  4. 医疗设备:便携式医疗仪器(心电图机、血氧仪)的传感器接口防护,低电容不影响生理信号传输;
  5. 通信设备:路由器、交换机的以太网接口,光纤收发器的信号接口防护,抑制高速信号中的瞬态干扰。

四、环境适应性与可靠性

除宽温工作范围外,ESD3Z5.0C还具备良好的环境可靠性:

  • 湿度适应性:可在5%~95%相对湿度(无凝露)环境下长期工作;
  • 机械可靠性:SOD-323封装引脚抗弯折能力符合行业标准,可承受PCB组装机械应力;
  • 长期稳定性:低漏电流(1μA)确保正常工作时无额外功耗,重复脉冲测试100次后性能无衰减。

五、品牌与封装信息

  • 品牌:KUU,专注过压保护器件研发,产品符合RoHS环保标准;
  • 封装:SOD-323,表面贴装封装,适配自动化贴装生产;
  • 引脚定义:无极性,引脚1/2可互换,简化电路布局。

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
