SLVU2.8-4 — 四路单向TVS/ESD保护器件产品概述
一、产品简介
SLVU2.8-4 是台舟电子（TECH PUBLIC）推出的四路单向瞬态电压抑制器（TVS/ESD），封装为SO-8，专为接口保护设计，能同时对静电放电（ESD）和浪涌（Surge）事件提供可靠的瞬态抑制。器件符合 IEC 61000-4-2、IEC 61000-4-4 及 IEC 61000-4-5 等抗扰度标准，适用于消费电子、通信接口和工业控制等场景。
二、关键电气参数
- 钳位电压（Vc）：10 V（在规定脉冲条件下的峰值钳位）
- 击穿电压（Vbr）：4.3 V
- 反向耐压/工作反向电压（Vrwm）：2.8 V（建议最大连续反向电压）
- 峰值脉冲功率（Ppp）：100 W（脉冲条件下瞬态能量承受能力）
- 峰值脉冲电流（Ipp）：10 A（器件可承受的最大瞬态电流）
- 反向漏电流（Ir）：1 μA（在 Vrwm 条件下的典型反向电流）
- 结电容（Cj）：4.7 pF（对高速信号影响较小）
- 通道数：4 路，极性：单向，类型：ESD/TVS
三、主要特性与优势
- 四路集成，节省PCB空间，简化多通道接口的防护设计。
- 单向结构适合对地抑制直流侧或单向信号线的瞬态冲击。
- 低结电容（4.7 pF），对高速数据线（如USB、HDMI、LVDS 等）干扰小。
- 低漏电流（1 μA）可保证对敏感低功耗系统的影响最小。
- 符合多项IEC抗扰度标准，适合经过规范性测试的产品设计。
四、典型应用场景
- USB、串口、HDMI、MIPI、摄像头模块等高速数据接口的ESD与浪涌保护；
- 以太网PHY接口、PoE 辅助保护（配合其它防护元件）；
- 工业控制器、测量设备、消费电子外设的输入/输出端口保护；
- 需要多路保护且受限于PCB面积的便携式设备。
五、设计与使用建议
- 布局：将SLVU2.8-4尽可能靠近被保护的连接器或信号源，走线最短且直接接地；
- 接地：在器件接地端附近布置足够的地铜并增加过孔以降低地回路阻抗，提高抑制效果；
- 串联元件：对高频敏感信号可配合小阻值串联电阻或共模滤波，以减少残压与反射；
- 热与能量管理：在可能遇到高能脉冲的应用中，注意器件的脉冲能量分配与系统整体保护策略，必要时并联更大功率防护器件或使用多级防护。
- 焊接与封装：遵循SO-8封装的回流焊规范，避免过高温度和长时间加热造成元件性能退化。
六、封装与品牌信息
- 封装：SO-8，适合SMT工艺，便于批量生产与自动化贴装。
- 品牌：TECH PUBLIC（台舟电子），型号：SLVU2.8-4。
总结：SLVU2.8-4 为多通道、低容、高能量承受能力的单向TVS器件，特别适合需要兼顾ESD抗扰度与高速信号完整性的接口保护方案。按照上述布局与使用建议设计，可在实际产品中实现稳健的瞬态保护。若需原理图示例、封装尺寸或应用参考电路，可提供进一步资料。

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.
