PESDNC2XD12VB TVS/ESD保护器件产品概述

一、产品核心定位

PESDNC2XD12VB是芯导(Prisemi)推出的双向瞬态抑制二极管(TVS)/静电放电(ESD)保护器件,专为电子设备的静电和浪涌防护设计,兼顾小封装、低电容与高防护能力,适配消费电子、通信、物联网等领域的高密度、高速信号接口防护需求。

二、关键电气与封装参数

该器件的核心参数明确了其防护性能边界,具体如下:

2.1 电气参数

参数名称 数值规格 实际意义 极性 双向 可同时防护正负方向的静电/浪涌过压,无需额外匹配反向器件 反向截止电压(Vrwm) 12V 正常工作时允许的最大反向电压,不触发保护功能 击穿电压(Vbr) 15V 过压达到此值时器件开始导通,启动防护 钳位电压(Vc) 23V 峰值脉冲电流下的最大钳位电压,直接决定后端电路的安全裕度 峰值脉冲电流(Ipp) 3A@8/20μs 耐受8μs上升沿、20μs下降沿的浪涌脉冲能力,覆盖常见ESD/浪涌波形(如HBM、MM) 反向漏电流(Ir) 1μA(典型) 正常工作时的反向漏电流极小,不影响电路功耗 结电容(Cj) 8pF(典型) 低电容特性不干扰高速信号传输(如USB 3.0、HDMI 2.0等)

2.2 封装参数

  • 封装类型:DFN0603-2L(双端无引脚封装)
  • 尺寸:0.6mm×0.3mm(极小封装)
  • 优势:节省PCB空间,适配小型化、轻薄化产品设计,支持自动化贴装

三、核心性能特性

  1. 双向防护全覆盖:无需区分正负方向,简化电路设计,有效抑制正负静电脉冲(如人体接触产生的ESD)和浪涌过压;
  2. 低钳位电压保障安全:23V的钳位电压远低于多数敏感芯片的损坏阈值(通常30V以上),可快速将过压钳位至安全范围;
  3. 高脉冲耐受能力:3A的峰值脉冲电流可应对日常使用中的多次静电放电(如IEC 61000-4-2的接触放电8kV、空气放电15kV);
  4. 低电容适配高速信号:8pF的结电容对高频信号衰减极小,适合USB、HDMI、以太网等高速接口的防护,不影响信号完整性;
  5. 小封装高密度集成:DFN0603-2L封装仅为0603尺寸,可在狭小PCB空间内实现多端口防护,满足智能手机、智能穿戴等产品的小型化需求。

四、典型应用场景

该器件的参数特性使其适配多类电子设备的防护需求,典型应用包括:

  1. 消费电子终端:智能手机、平板电脑、笔记本电脑的USB Type-C接口、耳机孔、SIM卡槽等端口的ESD防护;
  2. 通信设备:路由器、交换机的以太网接口(RJ45)、射频模块(RF)的浪涌/ESD防护;
  3. 物联网设备:智能手表、智能家居传感器(如温湿度传感器)、工业物联网节点的信号输入端口防护;
  4. 小型电子模块:无人机遥控器、便携式医疗设备(如血糖仪)的接口防护。

例如,在智能手机的USB Type-C接口中,PESDNC2XD12VB可并联在信号线上,当用户插拔数据线产生静电时,器件快速导通,将过压钳位至23V以下,保护后端的USB控制器芯片不被损坏。

五、品牌与可靠性说明

芯导(Prisemi)是国内专注于功率半导体与保护器件的领先厂商,其产品符合IEC 61000-4-2(ESD测试)、IEC 61000-4-5(浪涌测试) 等国际标准,可靠性经过量产验证:

  • 器件可承受多次静电放电(>1000次循环),性能无衰减;
  • 封装工艺稳定,支持SMT贴装(回流焊温度符合行业规范);
  • 广泛应用于华为、小米等主流终端厂商的产品中,市场验证充分。

总结:PESDNC2XD12VB是一款高性价比的双向TVS/ESD保护器件,兼具小封装、低电容、高防护的特点,可满足多数电子设备的静电与浪涌防护需求,是高密度、高速接口设计的理想选择。

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
