UMW ESD5Z5.0C 瞬态抑制二极管产品概述

ESD5Z5.0C是友台半导体(UMW)推出的单路瞬态抑制二极管(TVS),专为低电压电子系统的静电放电(ESD)及电快速瞬变脉冲群(EFT)防护设计,具备小封装、低漏电流、快速响应等特点,广泛适配消费电子、移动终端等领域的信号/电源线路防护需求。

一、产品核心定位与防护目标

该器件属于单通道低电压TVS,核心目标是在不干扰电路正常工作的前提下,吸收/钳位瞬态过压(如ESD脉冲、EFT干扰),避免后级敏感元件(微控制器、传感器、接口芯片)因过压损坏。其防护性能符合国际电磁兼容标准IEC 61000-4-2(ESD) 与IEC 61000-4-4(EFT),可有效应对实际应用中的瞬态干扰场景。

二、关键电气参数深度解析

ESD5Z5.0C的参数针对低电压系统优化,核心参数及意义如下:

1. 反向截止电压(Vrwm=5V)

电路正常工作时的最大反向偏置电压,确保在3.3V/5V系统中处于截止状态,无明显导通电流,不干扰电路功能。

2. 击穿电压(Vbr=9V)

反向偏置达到9V时进入雪崩击穿,快速导通吸收瞬态能量,是过压防护的启动阈值。

3. 钳位电压(Vc=9.5V)

峰值脉冲下的最大端电压,远低于多数敏感芯片的耐受电压(如10V以上),直接决定防护效果。

4. 峰值脉冲功率(Ppp=75W@8/20μs)

在IEC标准浪涌波形(8/20μs)下的最大承受功率,体现瞬态能量吸收能力,满足一般消费电子需求。

5. 反向漏电流(Ir=1μA)

截止状态下的反向电流,低漏电流可减少电池供电设备的功耗损耗。

6. 结电容(Cj=15pF)

寄生电容值,适合中低速信号线路(USB 2.0、I2C、UART等),不影响信号完整性。

三、封装与可靠性设计

ESD5Z5.0C采用SOD-523封装,尺寸约1.6mm×0.8mm×0.6mm,属于小型贴片封装,适配高密度PCB设计(如智能手机、智能手表),兼容标准回流焊工艺。

可靠性方面,器件通过IEC 61000-4-2(接触放电±8kV、空气放电±15kV) 与IEC 61000-4-4(4kV/5kHz) 测试,工作温度范围通常为-55℃~150℃,可适应不同环境下的长期稳定工作。

四、典型应用场景

该器件适用于以下场景:

  1. 移动终端:智能手机、平板的充电接口、耳机接口、USB接口防护;
  2. 便携式电子:蓝牙耳机、智能手表、运动相机的信号线路防护;
  3. 消费电子:电视、机顶盒、路由器的HDMI、USB接口防护;
  4. 工业控制:3.3V低电压传感器、PLC输入输出接口的瞬态干扰防护。

五、选型与使用注意事项

  1. 电压匹配:电路正常电压需≤Vrwm(5V),避免器件提前导通;
  2. 钳位适配:后级元件耐受电压需≥Vc(9.5V),保证防护有效性;
  3. 信号频率:100MHz以上高速信号(如USB 3.0)需结合测试,或选更低结电容器件;
  4. 封装焊接:SOD-523需匹配对应焊盘设计,确保焊接可靠性。

总结而言,ESD5Z5.0C是一款性价比高的单路低电压TVS,兼顾小封装、低漏电流与可靠防护,是消费电子、移动终端等领域低电压系统瞬态防护的常用选型。

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
