芯导PESDNC3FD5VB ESD防护器件产品概述

一、产品定位与核心用途

PESDNC3FD5VB是芯导(Prisemi)推出的双向ESD瞬态防护器件,核心作用是为敏感电子电路提供静电放电(ESD)和电快速瞬变脉冲群(EFT)防护,避免电路因瞬态过压损坏。其设计针对小型化、低功耗应用场景,适配消费电子、通信设备等领域的单路信号/电源线路防护需求,无需额外匹配防护方向,简化电路设计。

二、关键电气参数详解

2.1 基础防护阈值与极性

  • 双向极性:可同时抑制正、负方向的瞬态过压,无需区分输入输出方向,降低电路设计复杂度;
  • 反向截止电压(Vrwm)5V:正常工作时,当电路电压低于5V,器件处于截止状态,不干扰信号传输;
  • 击穿电压(Vbr)6.2V:电压超过6.2V时器件开始导通,快速将过压钳位至安全范围;
  • 钳位电压(Vc)7V/8V/9V:不同脉冲强度下的钳位值(需结合实际应用确认),确保过压被限制在电路耐受阈值内。

2.2 脉冲耐受能力

  • 峰值脉冲电流(Ipp)5A:可承受最高5A的瞬态脉冲电流冲击,满足常见ESD/EFT场景的防护需求;
  • 峰值脉冲功率(Ppp)100W@8/20us:基于标准8/20us浪涌波形的功率耐受能力,符合IEC 61000-4系列防护标准。

2.3 静态特性与结电容

  • 反向漏电流(Ir)1uA:截止状态下漏电流极小,不影响电路静态功耗;
  • 结电容(Cj)16.5pF:中等结电容值,适配音频、低速数字信号(如USB 2.0、音频接口)等场景,对高频信号干扰可控。

2.4 通道数

单路通道设计,适合单条信号线路或电源支路的独立防护,避免多通道串扰。

三、封装与可靠性设计

3.1 小型化DFN封装

采用DFN1006-3L封装,尺寸约1.0mm×0.6mm×0.4mm(典型值),无引脚设计具有以下优势:

  • 体积小,适配智能手机、无线耳机等小型化设备的高密度PCB布局;
  • 散热性能好,可快速 dissipate 瞬态脉冲能量;
  • 引脚电感低,响应速度快,防护延迟小(ns级)。

3.2 国际标准合规性

防护等级符合IEC 61000-4-2(ESD防护) 和 IEC 61000-4-4(EFT防护) 标准,可有效抵御:

  • 人体静电放电(接触放电8kV、空气放电15kV);
  • 电快速瞬变脉冲群(EFT)干扰,满足工业级和消费级设备的可靠性要求。

四、典型应用场景

PESDNC3FD5VB的参数特性使其适配以下场景:

  1. 消费电子终端:智能手机、平板、无线耳机的USB接口、音频接口、充电端口防护;
  2. 通信设备:路由器、交换机的以太网端口、WiFi模块信号端口防护;
  3. 小型电子设备:智能穿戴(手表、手环)、便携式蓝牙音箱的信号/电源线路防护;
  4. 低功耗工业设备:小型传感器、控制器的信号输入输出防护(需结合设备工作电压确认)。

五、品牌与质量保障

芯导(Prisemi)是国内专注于功率半导体、防护器件的知名厂商,PESDNC3FD5VB经过严格可靠性测试(温度循环、湿度老化等),符合RoHS环保标准,产品一致性好,可稳定应用于批量生产场景。

该器件通过平衡防护性能、体积和成本,成为小型化电子设备ESD防护的高性价比选择。

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
