USBLC6-2SC6 产品概述

一、概述

USBLC6-2SC6 是东沃(DOWO)推出的一款双路单向瞬态电压抑制器(TVS),专为 USB 与高速数据信号线的静电放电(ESD)与雷击浪涌(SURGE)保护而设计。器件在工作电压 5V 下提供高效的瞬态钳位,峰值脉冲功率达到 75W(tp = 8/20μs),可在恶劣电磁环境下保护终端设备的接口和敏感芯片。

二、主要特性

  • 单向保护,适合对地抑制正脉冲过压。
  • 反向工作电压(Vrwm):5V,适配 USB 5V 电源总线与数据线保护需求。
  • 击穿电压(VBR):6V,确保在过压时可靠触发导通。
  • 峰值脉冲电流(Ipp):4.5A(8/20μs)。
  • 峰值脉冲功率(Ppp):75W(8/20μs)。
  • 典型钳位电压:约 10V(在标准 8/20μs 测试条件下),最大可达 15V,能有效限制瞬态电压对下游器件的冲击。
  • 反向漏电流(Ir):1 μA(室温下典型值)。
  • 结电容(Cj):0.8 pF,低电容设计对高速数据传输影响极小。
  • 通道数:双路,独立保护两条信号线或一条信号线与电源线组合。
  • 工作温度范围:-40°C ~ +85°C。
  • 符合 IEC 61000-4-2(ESD)及 IEC 61000-4-5(浪涌)测试等级要求。
  • 封装:SOT-23-6L,体积小、易贴片,适合空间受限的移动及消费类产品。

三、典型应用场景

  • USB 2.0 / USB OTG 接口保护。
  • 手机、平板和笔记本的外部接口保护。
  • USB 集线器、充电器、车载娱乐系统接口。
  • 工业控制与仪器仪表的通信口防护。
  • 任何需在限制电容下实现高速数据线保护的场合。

四、封装与 PCB 布局建议

  • 封装为 SOT-23-6L,双通道引脚布局利于靠近连接器放置。
  • 建议将器件靠近被保护的连接器引脚放置,走线最短且宽度适中,以减少感抗与寄生电阻。
  • 将器件地端(GND)焊盘连接至大面积接地平面,且保持回流路径短且粗。
  • 对于高频高速信号,避免在保护器与信号路径之间增加额外串联电感或不必要的走线弯折,以维持低插入损耗和信号完整性。

五、可靠性与合规性

USBLC6-2SC6 通过 IEC 61000-4-2 ESD 等级测试以及 IEC 61000-4-5 浪涌测试,可在实际产品中有效减轻静电与浪涌造成的功能故障与元件损伤。器件在工业级温度范围内稳定工作,适合要求长期可靠性的消费与工业应用。

六、为何选用 USBLC6-2SC6

  • 低结电容(0.8 pF)确保对高速数据传输的最小干扰。
  • 75W 峰值功率与 4.5A 峰值脉冲电流为常见干扰事件提供足够余量。
  • SOT-23-6L 小封装利于紧凑设计与自动化贴装。
  • 东沃品牌供应与筛选,便于批量采购与一致性控制。

七、订购信息

  • 品牌:DOWO(东沃)
  • 型号:USBLC6-2SC6
  • 封装:SOT-23-6L
  • 联系供应链或授权分销商获取样片、数据手册和最小订购量信息。

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
