PESD5V0L1UL 产品概述

一、简介

PESD5V0L1UL 是 UMW(友台半导体)推出的一款单向瞬态抑制器,专为对静电放电(ESD)和瞬态脉冲干扰提供可靠保护而设计。器件采用小型 SOD-882 封装,针对计算机外设、音视频设备等对信号完整性和体积有要求的应用场景进行了优化。

二、主要技术参数

  • 极性:单向(Unidirectional)
  • 反向截止电压 Vrwm:5 V
  • 击穿电压 VBR(典型):6.8 V
  • 钳位电压 VCL(典型):12 V
  • 峰值脉冲电流 Ipp:3.5 A @ 8/20 µs
  • 峰值脉冲功率 Ppp:42 W @ 8/20 µs
  • 反向泄漏电流 Ir:10 nA(典型,静态)
  • 结电容 Cj / 二极管电容 Cd:25 pF
  • 通道数:单路
  • 防护等级:符合 IEC 61000-4-2,4 级(可达 26 kV ESD)
  • 封装:SOD-882
  • 类型:ESD 抑制器

三、关键特性与优势

  • 低钳位电压:典型 VCL = 12 V,可在短脉冲事件中有效限制过压,保护下游电路。
  • 极低泄漏电流:Ir = 10 nA,有利于在高阻抗或低功耗电路中保持正常工作电流。
  • 较高脉冲承受能力:Ipp = 3.5 A(8/20 µs)与 Ppp = 42 W 能承受严苛的静电和脉冲干扰事件。
  • 低结电容:Cd = 25 pF,在许多音频、视频及低速数字接口中对信号失真影响小,能兼顾防护与信号完整性。
  • 单向结构:适用于有明确电源极性的 5 V 系统(Vrwm = 5 V),在正常工作时呈高阻状态,发生瞬态时迅速导通夹止电压。

四、典型应用场景

  • 计算机及其外设(键盘、鼠标、USB 2.0 等低速接口)
  • 音频与视频设备(模拟音频线、复合视频与低速数字视频接口)
  • 消费电子端口保护(充电口、控制信号线)
  • 任何需在有限空间内实现单路 ESD 保护的接口

五、封装与可靠性

SOD-882 小封装便于贴片安装,适合高密度 PCB 布局。器件符合 IEC 61000-4-2 等级 4 要求(可达 26 kV),在经过合适的 PCB 布局和接地处理后可提供长期稳定的防护性能。低泄漏和低电容特性也有助于在对功耗和信号完整性敏感的系统中维持可靠性。

六、设计建议与注意事项

  • 放置位置:将 PESD5V0L1UL 靠近需保护的外部接口或连接器,尽量缩短信号线与接地回路以降低寄生电感。
  • 接地处理:良好、短而粗的接地回路能够显著提升放电能力和降低钳位电压。
  • 信号速率匹配:Cd = 25 pF 适合多数音视频与低速数字信号;若用于高速接口(如 USB3.0、PCIe 等),需评估电容对信号链的影响或选择更低电容的器件。
  • 功率等级:器件额定为 8/20 µs 波形下 Ppp = 42 W,针对多次高能脉冲或更长波形应结合系统整体防护策略(如串联电阻、L-C 滤波或多级防护)。

总结:PESD5V0L1UL 以其低钳位、低泄漏、较低结电容和良好的脉冲承受能力,为 5 V 级别的外部接口提供经济且可靠的单路 ESD 保护方案,适合计算机外设、音视频与一般消费电子的防护需求。

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
