PRTR5V0U2X 产品概述

一、产品简介

PRTR5V0U2X 是友台半导体(UMW)推出的一款双向ESD保护二极管,封装为 SOT-143,专为高速信号线和 5V 工作电压系统设计。器件在瞬态脉冲事件下可提供可靠的钳位和能量吸收能力,满足严苛的电磁兼容与静电放电要求。

二、主要电气参数

  • 反向截止电压 Vrwm:5V(适用于典型 5V 总线保护)
  • 击穿电压(Vbr):7.2V
  • 钳位电压(Vc):10V(在脉冲条件下有效限制过冲)
  • 峰值脉冲电流 Ipp:3.5A @ 8/20µs
  • 峰值脉冲功率 Ppp:40W @ 8/20µs
  • 反向漏电流 Ir:50nA(典型,保证低泄漏)
  • 结电容 Cj:0.35pF(超低电容,适合高速差分/单端信号)
  • 极性:双向(双向夹位,适合数据线双向干扰抑制)

三、抗扰度与认证

符合IEC 61000-4-2(ESD 静电放电)、IEC 61000-4-4(EFT/脉冲群)及 IEC 61000-4-5(浪涌)相关测试要求,能在典型工业及消费类应用中对瞬态过电压提供快速、稳定的保护路径。

四、应用场景

  • USB、HDMI、DP 等高速数字接口的差分信号保护
  • 手机、平板、笔记本等便携设备外部接口防护
  • 工业现场总线及通讯端口(TTL/RS-485 等)的瞬态抑制
  • 任何 5V 或以下工作电压的敏感模拟/数字输入输出线

五、封装与布局建议

SOT-143 封装小巧,便于贴片自动化。建议将器件尽量靠近受保护的接口或芯片引脚放置,保护引线短且宽,接地面采取连续大面积地平面,并在器件到地之间布置低阻抗回流路径,以提升吸收能力并降低环路感应。

六、使用注意事项

  • 器件为瞬态脉冲保护元件,不用于连续功率限流或定常电压稳压。
  • 确保瞬态能量(按 8/20µs 标准)不超过器件额定 Ppp、Ipp。
  • 在高频或差分通道设计中,0.35pF 的低结电容可最大程度降低信号失真,但仍需与系统阻抗匹配考虑。
  • 关注工作环境温度与焊接热工艺,避免热应力影响可靠性。

PRTR5V0U2X 以其低电容、低漏电、双向钳位及符合多项 IEC 标准的抗扰能力,是面向 5V 及高速信号接口的理想瞬态保护选择。若需详细的典型特性曲线、封装图或PCB参考设计,可进一步索取数据手册。

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
