Prisemi芯导PESDNC9D5VB双向ESD防护器件产品概述

一、产品定位与核心功能

PESDNC9D5VB是芯导(Prisemi)推出的单路双向ESD防护器件,专为5V级低电压电子系统设计,核心作用是抵御静电放电(ESD)、电快速瞬变脉冲群(EFT)等电磁干扰,保护后端敏感元件(如微控制器、传感器、通信接口芯片)免受过压损坏。其设计兼顾防护性能、信号完整性与小型化需求,是消费电子、可穿戴设备等高密度电路的理想防护方案。

二、关键电气参数详解

该器件参数针对低功耗、高频场景优化,各参数作用清晰:

  1. 双向极性:无需区分电路正负极,可直接并联在信号/电源线路两端,简化PCB布线与设计流程;
  2. 反向截止电压(Vrwm):5V:匹配5V供电系统(多数消费电子、物联网节点),正常工作时无额外导通损耗;
  3. 钳位电压:15V:遭遇ESD脉冲时快速导通,将线路电压钳位在15V以内(远低于芯片耐压阈值),避免后端元件损坏;
  4. 峰值脉冲电流(Ipp):5.5A:可承受主流静电冲击强度(如人体静电模型HBM、机器模型MM),应对日常使用中的静电干扰;
  5. 击穿电压:6.7V:略高于Vrwm,确保正常工作时器件截止、无功耗,干扰来临时快速响应;
  6. 反向电流(Ir):1uA:漏电流极低,几乎不影响系统待机/工作功耗,适合对功耗敏感的可穿戴设备;
  7. 结电容(Cj):12pF:低电容对高频信号传输影响极小,适配USB 2.0/3.0、HDMI、音频接口等高频线路;
  8. 单路通道:针对单路信号/电源防护,可并联多颗实现多路防护。

三、封装与可靠性设计

  1. 封装形式:SOD-923:超小型表面贴装封装(典型尺寸1.6mm×0.8mm×0.5mm),节省高密度PCB布局空间,适配智能手机、智能手表等小型设备;
  2. 国际标准认证:符合IEC 61000-4-4(电快速瞬变脉冲群) 和 IEC 61000-4-2(静电放电) 标准,经测试可通过对应等级干扰冲击,可靠性有权威背书;
  3. 环境适应性:采用成熟封装工艺,工作温度范围覆盖-55℃~125℃(参考芯导同类产品),满足不同场景的环境需求。

四、典型应用场景

PESDNC9D5VB的参数特性使其适用于多类低电压、高频、小型化设备:

  1. 消费电子终端:智能手机、平板电脑的USB接口、音频接口、SIM卡槽;
  2. 可穿戴设备:智能手表、手环的充电触点、传感器(心率/加速度计)接口、蓝牙天线;
  3. 物联网节点:智能家居传感器(温湿度/人体感应)、智能门锁的信号/电源电路;
  4. 小型便携设备:蓝牙耳机、无线耳机的充电端口、触控按键电路;
  5. 车载低端应用:车载USB接口、车载蓝牙模块等。

五、品牌与产品优势总结

依托芯导的功率半导体技术积累,PESDNC9D5VB具备核心优势:

  • 防护全面:双向极性覆盖正负静电,低钳位电压保障元件安全;
  • 信号兼容:低结电容适配高频信号,不影响传输质量;
  • 低功耗:1uA漏电流对系统功耗无显著影响;
  • 小型化:SOD-923封装适配高密度布局;
  • 高可靠:符合国际电磁兼容标准,经严格测试验证。

该器件是低电压电子系统中性价比高、性能均衡的ESD防护解决方案,能有效提升产品的静电抗干扰能力与使用寿命。

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
