USBLC6-2P6 产品概述

一、产品简介

USBLC6-2P6 是东沃(DOWO)推出的一款双路单向 TVS 晶体管,采用超小型 SOT-563 封装,专为 USB 供电与数据接口的瞬态浪涌和静电放电(ESD)防护而设计。器件在-40℃至+125℃的工作温度范围内稳定工作,适用于消费电子、外设、移动设备及工业接口等场合。

二、主要电气参数

  • 钳位电压(Vc):12 V(典型钳位水平,针对脉冲条件下对输出的限定)
  • 工作反向电压(Vrwm):5 V(适配 5 V 总线)
  • 击穿电压(Vbr):6 V
  • 峰值脉冲功率(Ppp):60 W @ 8/20 μs
  • 峰值脉冲电流(Ipp):4.5 A @ 8/20 μs
  • 反向漏电流(Ir):1 μA(在 Vrwm 下)
  • 结电容(Cj):0.6 pF(单通道,低电容利于高速信号完整性)
  • 通道数:双路(两路独立保护)
  • 极性:单向(对地钳位)
  • 防护等级:符合 IEC 61000-4-2 静电放电防护要求
  • 封装:SOT-563
  • 品牌:DOWO(东沃)

三、特点与优势

  • 低结电容(0.6 pF):对 USB2.0 等高速数据线影响小,保持信号完整性,减少插损与时延失真。
  • 双路独立设计:单封装内可保护两条差分或两条独立信号线,节约 PCB 空间与成本。
  • 单向钳位:在正向工作时对地钳位,适合保护 5 V 总线与数据线免受上升的瞬态电压损害。
  • 小型封装 SOT-563:占板面积小,适合紧凑型手机、平板及外设接口布局。
  • 良好的脉冲功率吸收能力(60 W@8/20μs):可以承受典型的工业脉冲与雷击诱发浪涌。
  • 宽温工作范围:适合消费级与工业级应用环境。

四、典型应用场景

  • USB2.0/USB3.0(数据线或 VBUS 辅助保护时选型需注意电容)
  • 手机、平板、USB 外设、充电器与数据线保护
  • 主板 I/O 接口、扩展坞与车载娱乐系统的瞬态保护
  • 需要在有限 PCB 空间内实现双通道 ESD 与浪涌保护的场合

五、封装与布局建议

  • 建议将器件靠近被保护的连接器布置,缩短走线长度以降低回路电感。
  • TVS 的地端应连接到低阻抗地平面,尽可能使用多个过孔实现快速回流。
  • 对于连续或更高能量的浪涌,建议在系统级增加串联阻抗(如阻抗匹配或 +5 V 线路上的阻容)以分担能量。
  • SOT-563 为小型贴片封装,回流焊时按厂家推荐的焊接曲线进行,以避免热损伤。

六、可靠性与注意事项

  • 尽管器件符合 IEC 61000-4-2,要达到系统级别的防护性能,还需考虑 PCB 设计、外壳接地与其它抑制元件配合。
  • 对于重复或极高能量的浪涌事件,应评估器件热稳态和累积损耗,必要时采用更高功率或并联保护方案。
  • 在选择用于高速差分信号保护时,关注总线特性阻抗与 TVS 电容对串扰和眼图的影响,必要时在样机上验证信号完整性。

总结:USBLC6-2P6 以其低电容、双路设计、小尺寸封装和良好的脉冲防护能力,为 5 V 总线与高速数据线提供实用且经济的瞬态防护解决方案,适合空间受限且对信号完整性有较高要求的应用。

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
