PESDUC2FD5VBA 静电浪涌保护器件产品概述

一、产品基本信息

PESDUC2FD5VBA是芯导(Prisemi)推出的双向TVS/ESD防护器件,专为电子设备的静电放电(ESD)和电快速瞬变脉冲群(EFT)浪涌防护设计。该器件采用超小型DFN1006-2L封装(1.0mm×0.6mm),适配高密度PCB布局,可广泛应用于消费电子、通信、工业控制等领域的信号/电源接口防护。

二、核心电气参数详解

1. 反向截止与击穿特性

  • 反向截止电压(Vrwm=5V):器件正常工作时,反向偏置不导通的最大电压,适配5V供电系统的线路防护;
  • 击穿电压(Vbr=9V):线路电压超过该值时,器件导通泄放过压能量,避免后端电路损坏。

2. 钳位电压与脉冲功率

  • 钳位电压(Vc=22V):测试条件为“峰值脉冲功率80W+8/20μs波形”,可将过压钳位在22V以内,保护敏感芯片(如MCU、射频IC);
  • 峰值脉冲功率(Ppp=80W):承受单脉冲浪涌的最大能量,满足IEC 61000-4-4的EFT防护要求。

3. 漏电流与结电容

  • 反向漏电流(Ir=1μA):5V偏置下漏电流极小,不影响低功耗设备(如可穿戴、物联网节点)的待机功耗;
  • 结电容(Cj=0.45pF):低电容设计减少对高频信号(USB 3.0、HDMI、Wi-Fi 6)的衰减,保障信号完整性。

4. 防护等级认证

符合IEC 61000-4-2(ESD) 和 IEC 61000-4-4(EFT) 标准,可应对±15kV接触放电、±8kV空气放电,以及电快速瞬变脉冲群干扰。

三、关键性能优势

1. 低电容适配高频应用

0.45pF结电容是核心优势,相比传统高电容器件,可避免高速信号串扰/衰减,无需额外匹配电容,适合高频接口防护。

2. 双向防护简化设计

无需区分正负极,直接并联在信号/电源线路两端(如VCC-GND、信号-GND),大幅简化PCB布局,减少设计错误。

3. 双重干扰防护覆盖

同时支持ESD(静电)和EFT(浪涌)防护,应对日常触摸静电、电源开关浪涌等场景,提升设备可靠性。

4. 小封装节省空间

DFN1006-2L封装仅占极小PCB面积,适配智能手机、智能手表等轻薄便携设备,满足高密度设计需求。

5. 低功耗适配低功耗设备

1μA漏电流在5V下仅消耗5μW,几乎不影响电池供电设备的待机时间。

四、典型应用场景

1. 消费电子

  • 智能手机/平板:USB Type-C充电口、数据接口ESD防护;
  • 可穿戴设备:智能手表、蓝牙耳机充电触点防护;
  • 智能家居:智能音箱、门锁接口防护。

2. 通信设备

  • 路由器/交换机:Ethernet端口、USB 3.0接口浪涌防护;
  • 基站设备:射频接口、控制信号线路EMC防护。

3. 工业控制

  • PLC:I/O端口、通信接口EFT防护;
  • 工业传感器:温度/压力传感器信号线路抗干扰。

4. 车载电子

  • 车载USB:充电/数据接口静电+浪涌防护;
  • 车载显示屏:触摸面板、信号线路ESD防护。

五、封装与应用注意事项

1. 封装规格

DFN1006-2L为2引脚表面贴装结构,适配自动化贴装,生产效率高。

2. 布局建议

  • 器件靠近被保护端口并联(信号端接器件一端,地端接另一端),减少引线电感(避免钳位效果下降);
  • 多接口防护时,每个接口单独并联器件,避免串扰;
  • 电源线路防护:并联在VCC与GND之间,保护电源管理芯片。

3. 可靠性说明

可承受多次脉冲冲击,工作温度范围(-40℃~+85℃)稳定,结电容随温度变化小,适合宽温环境应用。

该器件凭借“低电容、双向防护、小封装”的核心优势,成为电子设备接口防护的高性价比选择,可有效提升产品的电磁兼容性能与可靠性。

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
