ESD9X5.0ST5G-ES 产品概述

ESD9X5.0ST5G-ES 是 ElecSuper(静芯微)推出的一款单路单向瞬态电压抑制器,采用超小型 DFN1006-2(SOD-882)封装,专为 5V 级别电源与信号线的静电放电(ESD)及脉冲干扰保护设计。器件在小体积下提供高达 15A(8/20µs)峰值脉冲电流能力与 225W(8/20µs)峰值脉冲功率,具有低泄漏与可控的钳位特性,适合移动终端、消费电子与工业控制等空间受限但需要可靠保护的场合。

一、主要规格要点

  • 品牌:ElecSuper(静芯微)
  • 型号:ESD9X5.0ST5G-ES
  • 极性:单向(对地夹断型)
  • 反向工作电压 Vrwm:5V
  • 击穿电压(典型):6V
  • 钳位电压:15V(8/20µs 峰值脉冲条件下)
  • 峰值脉冲电流 Ipp:15A(8/20µs)
  • 峰值脉冲功率 Ppp:225W(8/20µs)
  • 反向静态电流 Ir:1µA(在 Vrwm 条件下)
  • 结电容 Cj:150pF
  • 通道数:单路
  • 工作温度范围:-40°C ~ +125°C
  • 防护等级:符合 IEC 61000-4-2 ESD 防护要求
  • 封装:DFN1006-2(SOD-882)

二、关键特性与设计要点

  • 高冲击能力:在标准 8/20µs 冲击波形下,器件可承受 15A 峰值脉冲电流并将瞬态能量限制在安全电压范围(典型钳位 15V),为敏感电路提供有效的瞬态浪涌抑制。
  • 低漏电流:反向工作电流仅 1µA(Vrwm = 5V),在待机或低功耗应用中对系统静态功耗几乎无影响。
  • 小封装:DFN1006-2 的超小占板面积(SOD-882)非常适合空间受限的便携设备与高密度 PCB 布局。
  • 容量影响:结电容约 150pF,属于中等偏高水平,对高速差分信号或高频射频链路会产生可见影响,应慎重用于高带宽信号线。更适合用于电源线、控制线、低速数据口或 PCB 上的通用保护点。
  • 温度与可靠性:工作温度覆盖 -40°C 至 +125°C,满足工业级温度需求,可在苛刻环境下长期稳定工作。

三、典型应用场景

  • 移动终端与便携设备(电源线、充电接口)
  • USB 2.0 类 5V 设备的端口保护(注意高速信号可能受结电容影响)
  • SIM 卡接口、GPIO、按键/开关输入保护
  • 工业控制与传感器接口的瞬态浪涌与静电防护
  • 车载私有总线或低速通信接口(在额定温度与电气条件下)

注:对于高速接口(例如 USB3.0、HDMI、PCIe、射频通道等),因本器件的 150pF 结电容可能影响信号完整性,不建议直接用于高速差分对的信号线。

四、封装与 PCB 实施建议

  • 封装:DFN1006-2(SOD-882),适合常规 SMT 回流焊工艺。
  • 置放建议:将器件靠近需保护的连接器或 PCB 边缘放置,走线尽量短且直接,减少寄生电感和阻抗。
  • 接地处理:单向 ESD 二极管需一端接至保护地(最好为 PCB 的器件参考地或接地平面),确保接地回路低阻抗,提升放电效率并降低钳位电压。
  • 焊接兼容性:兼容主流的 SMT 回流焊曲线,请在实际生产中参考元器件制造商提供的回流焊工艺参数以优化焊接质量。
  • 布局注意:对高频或差分信号,优先选用低电容保护器件;对电源线、低速单端数据线则可直接采用本器件保护。

五、选型与比较要点

  • 若系统工作电压接近 5V,本器件 Vrwm=5V 可在正常工作电压下不触发,遇到瞬态时快速钳位到安全电压(典型 15V),适用于要求常态不影响、动作快速的保护需求。
  • 关注钳位电压与被保护器件的最大承受电压,确保在脉冲条件下器件不会被击穿或损坏。
  • 若要求极低泄漏或超低结电容(用于高速信号),需对比更低 Cj 的专用高速 ESD 器件。

六、包装与订购信息

  • 型号:ESD9X5.0ST5G-ES
  • 品牌:ElecSuper(静芯微)
  • 封装:DFN1006-2(SOD-882)
  • 如需样片、批量报价或更详细的器件曲线(钳位 vs. 电流、漏电随温度变化等),建议联系供应商或参考厂商完整数据手册以获取典型 IV、VC 曲线和封装尺寸图。

总结:ESD9X5.0ST5G-ES 提供了在微小封装下优秀的脉冲能量吸收能力和低漏电特性,是电源线和低速信号线的实用 ESD 防护选择。但在高速/射频通路应用上需慎重评估结电容对信号完整性的影响。

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.
