PDWL050019 产品概述
一、产品简介
PDWL050019 是友台半导体（UMW）推出的一款四路低电容ESD保护二极管，专为高速信号线与接口电路提供可靠的浪涌与静电防护。器件采用 SOT-23-6 小型封装，集成四路保护通道，适合空间受限的消费类与工业电子产品。
二、主要性能特点
- 反向截止电压 (Vrwm)：5 V，适用于低电压信号总线。
- 击穿电压 (Vbr)：6 V（典型），确保在过压时可靠导通。
- 钳位电压 (Vclamp)：15 V，8/20µs 浪涌下有效限制电压幅值。
- 峰值脉冲功率 (Ppp)：150 W（8/20µs），可承受瞬态大能量冲击。
- 反向电流 (Ir)：1 µA（典型），在工作电压下漏电小，降低对信号线影响。
- 结电容 (Cj)：典型 0.5 pF / 0.8 pF（视通道与测试条件），对高速差分与单端信号影响小。
- 防护等级：符合 IEC 61000-4-2、IEC 61000-4-4、IEC 61000-4-5 标准。
三、典型应用场景
- USB、HDMI、DisplayPort、MIPI 等高速数据接口的端口保护。
- 手机、平板、笔记本与可穿戴设备的输入/输出端口。
- 工业控制与通信设备的信号线与传感器接口。
- PCB 边界处的静电放电防护与浪涌吸收。
四、封装与安装
产品采用 SOT-23-6 封装，体积小、便于贴片生产，适合自动化焊接。器件为四通道设计，可根据 PCB 布局将每路独立布线到需保护的信号线上。具体引脚定义与布局建议请参照官方数据手册以保证最佳性能。
五、选型与使用建议
- 选型时确认工作侧最高持续电压不超过 Vrwm（5 V），以避免误触发。
- 对高速差分对优先选择结电容较低的通道（0.5 pF），以减小信号失真。
- 在高能量环境建议配合适当的串联阻抗或磁珠，提升系统整体浪涌承受能力。
- 设计时按照 IEC 标准测试条件验证通道钳位电压与重复浪涌能力。
六、品牌与品质
PDWL050019 由 UMW（友台半导体）生产，供应稳定，适合规模化量产。有关可靠性、包装信息及更多电气特性，请参考友台半导体的完整数据手册与应用说明。
Request for quote
Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
