PESD5V0S1UB-N 产品概述

一、产品简介

PESD5V0S1UB-N 是 BORN(伯恩半导体)推出的一款单向瞬态电压抑制(TVS)二极管,封装为 SOD-523,专为保护 5V 及以下信号/电源线免受静电放电(ESD)、脉冲群(EFT)和浪涌冲击设计。器件响应迅速、体积小巧,适合空间受限的消费电子与工业控制场景。

二、主要参数

  • 钳位电压(Vc):18V(在规定冲击条件下)
  • 反向工作峰值电压 Vrwm:5V
  • 峰值脉冲功率 Ppp:250W @ 8/20µs
  • 峰值脉冲电流 Ipp:15A @ 8/20µs
  • 结电容 Cj:80pF(典型)
  • 反向漏电流 Ir:500nA(在 Vrwm 条件下典型值)
  • 极性:单向
  • 类型:ESD TVS
  • 防护等级:符合 IEC 61000-4-2、IEC 61000-4-4、IEC 61000-4-5 标准

三、性能特性

  • 快速钳位与低漏电:在大冲击电流下将瞬态电压有效钳位至约 18V,同时在正常工作电压下保持微安级漏电,便于节能与静态电流控制。
  • 中等结电容(80pF):对低速数字/控制信号及电源线影响较小,但对超高速差分信号(高频/USB3.0 等)可能产生一定影响,应谨慎评估。
  • 小型 SOD-523 封装:便于高密度 PCB 布局与自动贴装。

四、典型应用场景

适用于 USB 低速/全速(需评估电容)、串口(UART)、控制信号线、充电口前端保护、移动设备、智能家居与工业控制器等需要 5V 级别防护的场合。

五、PCB 布局与使用建议

  • 靠近受保护端口(如连接器)放置,最短的引线连接到地,以减少串联电感和环路面积。
  • 为高能量浪涌提供低阻抗回流路径,确保良好地平面连接。
  • 若用于高速差分线,需评估 80pF 对信号完整性的影响,必要时选择低电容型 TVS。

六、封装与可靠性

SOD-523 小型封装支持自动化贴装与回流焊接。焊接和储存按 JEDEC/IPC 标准处理,避免潮湿引起焊接缺陷。器件已通过 IEC 等抗扰度测试,能满足常见工业与消费级抗干扰需求。

七、总结

PESD5V0S1UB-N 在体积、耐浪涌能力和响应速度之间提供了均衡方案,适合需在受限空间内实现对 5V 等级接口的有效保护的应用。选型时结合结电容对信号完整性的影响与实际工作电压进行评估,以确保既能满足防护要求又不影响电路性能。

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
