SR05-ES 产品概述

一、产品简介

SR05-ES 是 ElecSuper(静芯微)推出的一款用于两路信号线的单向瞬态过压保护器件(ESD Protector)。器件采用 SOT-143 小封装,集成双路单向浪涌/静电防护功能,专为需要低电容、高可靠性保护的高速数据与接口电路设计。器件在保证低漏电与低结电容的同时,能承受较高的脉冲能量,适合移动终端、工业控制及消费电子的接口防护需求。

二、主要性能参数

  • 极性:单向(单向钳位,适用于带方向性的信号线)
  • 反向截止电压 Vrwm:5 V
  • 击穿电压 Vbr:6 V(典型)
  • 峰值脉冲电流 Ipp:5 A(8/20 μs)
  • 峰值脉冲功率 Ppp:180 W @ 8/20 μs
  • 钳位电压:约 15 V(在 Ipp 条件下测得)
  • 反向电流 Ir:1 μA(在 Vrwm 条件下,典型)
  • 结电容 Cj:单路约 0.8 pF,双路组合约 1.6 pF(典型)
  • 通道数:双路(Two-channel)
  • 工作温度范围:-40 ℃ ~ +125 ℃
  • 防护等级 / 兼容标准:IEC 61000-4-2(ESD)、IEC 61000-4-4(EFT)、IEC 61000-4-5(浪涌)
  • 封装:SOT-143(小尺寸,四引脚)

三、关键特性与优势

  • 极低结电容:单路约 0.8 pF,适合高速数据线,减小对信号完整性的影响。
  • 高脉冲能量承受能力:支持 180 W(8/20 μs)峰功率及 5 A 峰脉冲电流,能有效吸收电涌与大能量脉冲。
  • 单向钳位设计:适用于需反向隔离的接口或需在特定电压下保护的电路(典型 Vrwm 5 V)。
  • 低漏电流:Ir 典型为 1 μA,有助于降低静态损耗并适配低功耗系统。
  • 紧凑封装:SOT-143 占板面积小,利于空间受限的移动设备与便携式产品布局。
  • 工业温度范围:-40 至 +125 ℃,满足工业级应用环境要求。
  • 完整电磁兼容防护:通过 IEC 61000-4-2/4-4/4-5 三级抗扰度规范,增强系统现场抗干扰能力。

四、典型应用场景

  • 手机、平板和便携设备的外部 I/O 保护(如 USB、耳机接口等)
  • 高速数据接口:USB2.0、MIPI、LVDS、差分数据链路等(0.8 pF 的低电容有利于保持信号完整性)
  • 工业控制通讯接口(串口、以太网非专用端口的边缘保护)
  • 摄像头、显示接口保护(MIPI CSI、DSI 等前端保护)
  • 智能家居、物联网终端、传感器接口防护

五、封装与引脚(SOT-143)

  • 小型 SOT-143 封装,便于贴片与自动化生产。
  • 四引脚结构适合两路独立保护,每路一信号引脚加公共接地/参考引脚(具体引脚定义请参见器件数据手册)。

六、使用建议与 PCB 布局要点

  • 将 SR05-ES 尽可能靠近受保护的连接器或信号输入端放置,减小 PCB 上未保护的走线长度。
  • 保护器要保证有低阻抗的接地回路,建议在保护器附近打若干地通过(VIA)并尽量缩短到地平面连线。
  • 对于差分或高速信号,注意差分对长度与阻抗匹配,避免在保护器处产生不必要的阻抗突变。
  • 如需更高的系统级浪涌承受能力,可与串联电阻或电感配合使用以限制峰值电流。
  • 在布局时预留热散空间与良好的焊盘焊接条件以确保可靠性。

七、可靠性与认证

  • 工作温度范围覆盖工业级应用(-40 ℃ ~ +125 ℃)。
  • 器件在设计上满足 IEC 61000-4-2(静电放电)、IEC 61000-4-4(快速瞬变脉冲)、IEC 61000-4-5(浪涌)相关要求。
  • 建议在量产前依据实际系统环境做整机级的 ESD/浪涌兼容性验证,以确认 PCB 布局与接地策略的有效性。

八、订购信息与注意事项

  • 型号:SR05-ES;品牌:ElecSuper(静芯微)。
  • 封装:SOT-143,适配常规贴片生产工艺。
  • 在选型与设计时,请参考完整的数据手册获取详细的电气测量条件(如钳位电压测定电流、温度影响、典型波形等)及引脚定义、最大额定值与回流焊工艺说明。
  • 如需获得样片、可靠性测试报告或应用参考电路图,请联系经销商或厂商技术支持。

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
