TPD4EUSB30DQAR-TP 产品概述
一、产品简介
TPD4EUSB30DQAR-TP 是 TECH PUBLIC（台舟电子）提供的一款四路单向瞬态电压抑制/静电放电保护器（TVS/ESD），封装为 DFN2510-10。器件面向 USB 及其他低电压高速信号线的静电与浪涌保护需求，工作温度范围宽（-55℃ ～ +125℃），适用于工业级和消费类产品的环境。
二、主要特性
- 钳位电压：25 V（典型钳位能力，针对冲击电流时限值）
- 反向耐压（Vrwm）：5 V，适配 5 V 总线系统
- 击穿电压（Vbr）：8 V
- 峰值脉冲功率：100 W @ 8/20 μs（单脉冲峰值能量吸收能力）
- 峰值脉冲电流（Ipp）：4 A @ 8/20 μs
- 结电容（Cj）：0.3 pF（超低寄生电容，利于高速信号完整性）
- 反向电流（Ir）：400 nA（低漏电流，有利于低功耗系统）
- 极性：单向，四通道独立保护
- 防护级别：满足 IEC 61000-4-2 / 4-4 / 4-5（ESD、EFT、浪涌）标准
- 封装：DFN2510-10，小尺寸便于紧凑布局
三、典型应用
- USB 数据口（尤其对高速数据线要求低电容的保护）
- 智能手机、平板、笔记本等便携设备的外部接口保护
- 工业控制、测量与通信设备的信号端口防护
- 其他对 ESD、EFT 与浪涌有要求的高速差分或单端信号线
四、设计与布局建议
- 将器件尽量靠近外部连接器放置，以缩短走线并提高保护效率；保护端接地旁应设置多条过孔低阻连接至公共地。
- 由于为单向器件，注意方向性，确保对地钳位路径正确。
- 极低的结电容（0.3 pF）有利于信号完整性，但在需要严格阻抗控制的差分链路上仍建议配合匹配电阻和良好走线。
- 在高能脉冲环境下，确保 PCB 地平面与返回路径的连续性以避免地弹引起的二次干扰。
五、可靠性与封装信息
- 工作温度：-55℃ ~ +125℃，适应宽温度范围应用。
- 小型 DFN2510-10 封装，适合自动贴装与回流焊工艺，便于批量生产与成本控制。
- 推荐在样机阶段进行系统级 ESD/浪涌验证，确认在目标应用下的实际钳位与传导路径表现。
总结：TPD4EUSB30DQAR-TP 以其四路单向保护、超低结电容、工业级温度与符合 IEC 防护标准的能力，适合需要兼顾高速信号完整性与可靠防护的接口电路。

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.
