SRV05-4-HXY 产品概述

一、产品简介

SRV05-4-HXY 是华轩阳电子(HXY MOSFET)推出的一款五路单向ESD保护器件,采用 SOT-23-6L 小型封装,专为对低电容、高速信号线进行静电放电保护而设计。器件在反向截止电压 5V 条件下提供低钳位电压和快速响应,适合移动终端、接口保护、传感器及通信模块等场景。

二、主要参数

  • 极性:单向
  • 反向截止电压 (Vrwm):5 V
  • 钳位电压:8.5 V(典型)
  • 峰值脉冲电流 (Ipp):4 A(IEC 61000-4-5/标准脉冲条件)
  • 击穿电压:6 V
  • 反向电流 (Ir):1 μA(常温、Vrwm 下)
  • 通道数:5 路
  • 工作温度:-55 ℃ ~ +125 ℃
  • 防护等级:符合 IEC 61000-4-2 ESD 标准
  • 结电容 (Cj):0.4 pF;0.8 pF(典型,适用于高速差分/单端线)
  • 类型:ESD 保护器件
  • 封装:SOT-23-6L

三、主要特性与优势

  • 低钳位电压:8.5 V 的钳位值可在发生静电或瞬态冲击时保护后端敏感芯片,降低损伤风险。
  • 低漏电流:Ir 仅 1 μA,适用于电池供电和低功耗系统。
  • 低结电容:0.4 pF~0.8 pF 的低 Cj 对高速信号影响小,保证信号完整性,适合 USB、HDMI、MIPI 等高速接口。
  • 多路集成:5 路保护减少外部器件数,节省 PCB 面积和元件放置复杂度。
  • 宽工作温度:-55 ℃ 至 +125 ℃,适应工业级环境。
  • 小型封装:SOT-23-6L 方便自动贴装与空间受限应用。

四、典型应用

  • 智能手机、平板等移动终端的 I/O 口保护
  • 摄像头、显示接口(MIPI/DSI/CSI)线路防护
  • USB、UART、I2C、SPI 等通信总线的静电防护
  • 工业控制与传感器接口的浪涌与 ESD 抑制
  • 物联网终端与可穿戴设备的外围保护

五、封装与布线建议

  • 封装:SOT-23-6L,适合表面贴装生产。
  • 布线建议:保护器件到受保护信号线的连线应尽量短且直;保护二极管至地的回流路径应采用多颗地穿孔并靠近器件接地引脚以降低感抗。
  • 接地:确保器件接地良好且与系统地平面有低阻抗连接,避免通过芯片或长回路泄放 ESD 能量。

六、设计注意事项

  • SRV05-4-HXY 为瞬态抑制器,不适用于长期承受高电压或持续电流的场合;遇到重复或持续浪涌需评估散热与功率承受能力。
  • 在高速差分线应用中,请参考厂商提供的结电容分布(0.4 pF、0.8 pF)以评估对信号抖动和插入损耗的影响。
  • 与其它保护或滤波元件并用时,注意并联电容、阻抗匹配及滤波网络对保护性能的影响。

七、可靠性与规范

SRV05-4-HXY 按 IEC 61000-4-2 标准设计用于对抗静电放电事件,器件在额定工作温度范围内具有良好的热稳定性与长寿命表现。推荐在样机与系统级产品中进行 ESD 及浪涌完整性测试,以验证在目标应用中的实际保护效果。

如需封装尺寸图、典型电路图和详细电气特性曲线(钳位能量、动态电阻、各温度下漏电随电压变化等),建议向华轩阳电子索取产品手册和 S-parameter 数据以完成最终设计验证。

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
