PESDNC2FD5VB 产品概述

一、产品简介

PESDNC2FD5VB 是 Prisemi(芯导)推出的单路双向静电与浪涌保护器件(TVS/ESD),封装为超小型 DFN1006,专为对敏感信号线和低压供电线进行瞬态过压保护设计。器件针对工业级浪涌与静电脉冲,能在瞬态事件中吸收能量,保护后端器件不被击穿或损坏。

二、主要电气参数

  • 钳位电压(Vc):10V / 13V / 15V(不同型号或测量条件下典型值)
  • 击穿电压(Vbr):典型 6.7V
  • 反向截止电压 Vrwm:5V(适合 5V 系统)
  • 峰值脉冲功率 Ppp:80W @ 8/20 µs
  • 峰值脉冲电流 Ipp:5.5A @ 8/20 µs
  • 结电容 Cj:15 pF(低电容,适合高速信号线)
  • 反向漏电流 Ir:≈1 µA
  • 通道数/极性:单路 / 双向
  • 标称类型:ESD / TVS
  • 封装:DFN1006(超小型封装)
  • 符合标准:IEC 61000-4-2(静电放电)、IEC 61000-4-4(快速瞬变脉冲)

三、特点与优势

  • 双向保护:无需区分极性,适用于双向数据线或交流类瞬态。
  • 低结电容(15 pF):对高速接口(例如 USB、信号线)影响小,保留信号完整性。
  • 高能量吸收能力:80 W/8/20 µs 与 5.5 A 峰值脉冲电流,能有效抑制常见浪涌与 ESD 事件。
  • 低漏电流:1 µA 水平,有利于待机/低功耗系统。
  • 小体积封装:DFN1006 有利于空间受限的移动或便携产品设计。

四、典型应用场景

  • 5V 信号保护:USB、I2C、UART 等通用接口保护。
  • 通讯与接口板卡:防止外部连接器带入的静电与浪涌。
  • 工业与消费电子设备的输入输出保护。
  • 对需要低电容且高可靠性的高速数据线保护场合。

五、PCB 布局与使用建议

  • 保护器件尽量靠近受保护的外部端口或连接器放置,缩短引线长度以降低寄生电感。
  • 在器件与地之间使用单一、短的回流路径;若有多层板,建议在器件下方或附近放置连续地平面并通过多颗地通孔回流。
  • 对高速信号,注意 Cj 的影响,必要时在布线中做仿真确认信号完整性。
  • 对于功率散热,DFN1006 本身散热受限,若在高能事件频繁出现的环境,考虑增加散热铜箔或选择更高功率等级的器件。

六、选型与注意事项

  • 根据被保护电路能承受的最大钳位电压选择 10V/13V/15V 版本,确保在峰值冲击下后端器件不会超压。
  • 若用于严格的 5V 信号线,Vrwm=5V 的特性非常匹配,但要确认钳位电压在脉冲电流下不会损伤后端元件。
  • 注意环境与标准要求,器件满足 IEC 61000 系列测试要求,适合需要抗 ESD/EFT 能力的应用。

七、可靠性与封装信息

PESDNC2FD5VB 以 DFN1006 超小封装提供,适合空间受限设计,品牌为 Prisemi(芯导),在工业与消费类应用中具有良好的抗静电与抗浪涌表现。使用前建议参考器件数据手册中的典型波形、热阻和焊接工艺规范,以确保长期可靠性。

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
