ESD5Z5.0T1G 产品概述

一、产品简介

ESD5Z5.0T1G 是友台半导体(UMW)推出的一款单向瞬态电压抑制器(TVS),采用超小型 SOD-523 封装,专为 5V 类电源与 I/O 接口的静电与浪涌保护设计。器件对静电放电(ESD)和电快速瞬变(EFT)具有良好抑制能力,适用于消费电子、通信和工业控制等需可靠防护的小型终端设备。

二、主要参数

  • 极性:单向
  • 反向静态耐压 Vrwm:5.0 V(典型,适配 5V 系统)
  • 击穿电压 Vbr:6.2 V(在指定电流条件下)
  • 钳位电压 Vc:18.6 V(对应峰值脉冲)
  • 峰值脉冲电流 Ipp:9.4 A @ 8/20 µs 波形
  • 峰值脉冲功率 Ppp:174 W @ 8/20 µs 波形
  • 反向电流 Ir:50 nA(静态低漏)
  • 结电容 Cj:约 80 pF(典型值)
  • 防护标准:符合 IEC 61000-4-2(ESD)与 IEC 61000-4-4(EFT)
  • 封装:SOD-523(超小贴片)

三、功能与优势

  • 高效能防护:支持 8/20 µs 标准脉冲测试下 9.4 A 的电流冲击与 174 W 的瞬时功率吸收,能在瞬态事件中快速钳位,保护下游电路。
  • 低泄漏电流:反向电流仅约 50 nA,有利于电池供电与低功耗系统的静态性能。
  • 小封装:SOD-523 极小占板面积,适合空间受限的便携设备与高密度 PCB。
  • 中等结电容(80 pF):对多数控制信号与 USB2.0 类接口友好,但在超高速差分信号链路需评估其影响。
  • 标准合规:通过 IEC 61000 系列抗扰度测试,方便系统设计满足 EMC 要求。

四、典型应用场景

  • USB2.0、UART、I2C、SPI 等 5V 或兼容 5V 的接口保护(需评估电容对信号完整性的影响)。
  • 手机充电口、移动电源、便携式设备的输入端防护。
  • 工业控制模块、传感器接口、消费电子外设的静电浪涌防护。
  • 一般 PCB 上的电源轨与单端信号线的浪涌抑制。

五、设计与布局建议

  • 器件应尽量靠近受保护的连接器或接口放置,缩短引线与走线长度以降低感性耦合与环路面积。
  • 将 TVS 的地端短直接回到系统地(或接地平面),必要时增设多点接地或旁路电容以改善高频路径。
  • 对高频差分信号(如 USB3.0、HDMI 等),请先评估 80 pF 结电容对信号完整性的影响,必要时选用更低电容型号。
  • 遵循制造商推荐的回流焊工艺与热循环规范,避免超出封装耐热限制,确保良好焊接强度与可靠性。

六、选型与注意事项

  • 确认系统工作电压与 Vrwm 匹配:本型号 Vrwm=5V,适用于 5V 及以下的单端线路。
  • 核实钳位电压与保护等级:钳位 18.6V 在部分敏感器件可能仍需额外串联限流或保护级联。
  • 若应用在极端环境或需更高的脉冲能量吸收能力,请参考完整数据手册并考虑并联或使用更大功率的 TVS 器件。
  • 在批量导入设计前,建议按实际应用条件做 PCB 实测(带连线、电感、ESD 源位置)以验证防护效果与信号影响。

总结:ESD5Z5.0T1G 在体积与防护性能之间取得平衡,是保护 5V 类接口与电源轨的经济型选择。针对高频差分链路或超高能量冲击场合,请根据最终数据手册与系统要求谨慎评估。若需完整电气特性曲线、封装尺寸与回流焊建议,请参考 UMW 正式资料或联系供应商获取详细数据手册。

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
