PESD5V0V1BB 产品概述

一、产品简介

PESD5V0V1BB 是东沃(DOWO)出品的一款单路双向静电放电(ESD)与浪涌保护二极管,封装为超小型 SOD-523。器件为双向结构,适用于需要双极性过压保护的信号/电源线,工作温度范围宽(-55℃~+125℃),并满足 IEC 61000-4-2(ESD)与 IEC 61000-4-5(浪涌)规范,适合消费电子、通信接口及各种易受瞬态干扰的应用场景。

二、主要特性

  • 极性:双向(bidirectional),可对正负瞬态脉冲进行钳位保护
  • 反向截止电压 Vrwm:5 V(稳态耐压)
  • 击穿电压:5.5 V(典型)
  • 钳位电压:15 V(峰值脉冲条件下)
  • 峰值脉冲电流 Ipp:8 A(单次脉冲能力)
  • 峰值脉冲功率 Ppp:120 W(短脉冲功率吸收能力)
  • 反向电流 Ir:500 nA(在 Vrwm 条件下的小漏电流)
  • 结电容 Cj:15 pF(对高速信号会有影响,应注意信号完整性)
  • 通道数:单路
  • 工作温度:-55℃ 至 +125℃
  • 防护等级:符合 IEC 61000-4-5、IEC 61000-4-2 要求
  • 封装:SOD-523(超小体积,便于空间受限设计)

三、电气参数(主要)

该器件在标称工作电压 5 V 下提供稳态保护,击穿点约 5.5 V,当遭受 ESD/浪涌脉冲(例如峰值电流 8 A)时,器件将钳位到约 15 V 以保护后端电路。静态漏电小(Ir≈500 nA),但结电容约 15 pF,设计高速差分信号通道时需评估对信号的影响。

四、典型应用

  • USB/数据接口、GPIO、串口保护(非超高速差分线需评估电容影响)
  • 移动终端、物联网终端的外部接口保护
  • 消费电子产品信号/控制线防护
  • 工业与仪表设备的瞬态电压抑制

(注:如用于高速接口(如 USB 2.0/3.0、LVDS 等),请在 系统级检测信号完整性,15 pF 电容可能影响高速链路的眼图。)

五、PCB 布板与使用建议

  • 器件应尽量靠近被保护端口放置,走线短且粗以减小寄生电感与阻抗。
  • 双向器件的两端分别接到信号线两极或信号与参考地(或公共线)——常见接法为直接并联到保护点与地之间。
  • 尽量减少器件到地的回流路径长度,使用低阻抗地平面以提高泄放能力。
  • 对高速差分信号,建议评估并行电容造成的失真;必要时考虑更低 Cj 的保护元件或外置滤波/共模措施。
  • 焊接兼容常见回流工艺,注意避免过热、严格按照元件制造商的焊接曲线操作。

六、热与可靠性

器件额定工作温度 -55℃ 至 +125℃,适用于宽温环境下长期使用。长期可靠性取决于实际脉冲能量、工作环境及焊接工艺。建议进行产品级的 ESD 与浪涌验证以确认系统可靠性。

七、封装与订购信息

  • 型号:PESD5V0V1BB
  • 品牌:DOWO(东沃)
  • 封装:SOD-523,表面贴装,适合自动贴片与回流焊装配。
  • 通道:单路,双向保护

使用前请参考厂方完整数据手册以获取详尽的峰值钳位测试条件、浪涌曲线、封装尺寸及回流焊推荐曲线。针对关键或高速接口,建议在样机阶段进行信号完整性与系统级防护验证,确保在实际工作条件下达到预期保护效果。

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
