SR05-02CTG-ES 产品概述

一 产品简介

SR05-02CTG-ES 是 ElecSuper(静芯微)推出的一款双路单向 TVS 二极管,专为低压高速信号线与接口保护而设计。器件在 SOT-143 小封装内实现双通道独立保护,具备低结电容和极低漏电流特性,能够在工业级浪涌与静电放电事件中提供可靠钳位保护,满足 IEC 61000-4-5(浪涌)与 IEC 61000-4-2(静电)要求。

二 主要技术参数

  • 极性:单向
  • 反向截止电压 Vrwm:5 V
  • 击穿电压(典型):9 V
  • 钳位电压(Ipp = 7 A @ 8/20 μs):20 V
  • 峰值脉冲电流 Ipp:7 A @ 8/20 μs(单次脉冲)
  • 峰值脉冲功率 Ppp:140 W @ 8/20 μs
  • 反向电流 Ir:1 μA(典型/最大等级请参考数据表)
  • 通道数:双路(独立)
  • 结电容 Cj:0.5 pF(典型),1 pF(最大)
  • 封装:SOT-143
  • 防护等级/标准:IEC 61000-4-5、IEC 61000-4-2

三 主要特性与优势

  • 低结电容:典型 0.5 pF,最大 1 pF,适合 USB、LVDS、Camera、PCIe 等高速差分或单端数据线,能最大限度地减少信号失真与插入损耗。
  • 低漏电:反向漏电仅 1 μA,适合对待机功耗敏感的系统。
  • 高浪涌抗扰性:支持 7 A(8/20 μs)脉冲电流与 140 W 峰值功率,能有效吸收常见的线路浪涌事件。
  • 单向保护:当保护 5 V 及以下电源/信号线时,能提供确定的导通方向与钳位水平,避免反向误触发。
  • 紧凑封装:SOT-143 小尺寸利于 PCB 空间受限场合的布局与批量生产。

四 典型应用与使用建议

  • 典型应用场景:USB2.0/USB3.0 下游/上游接口保护、串口/以太网收发器 I/O 保护、摄像头/显示接口、移动设备及工业控制信号线保护等。
  • 布局建议:TVS 器件应尽量靠近被保护的接口或连线端子放置,走线尽量短且减少串联电感;器件地端应有良好接地回路以利能量散逸。
  • 热与浪涌考虑:在多次高能脉冲场合,建议评估器件温升与系统整体散热,必要时配合串联阻抗或其他外保护元件以分摊能量。
  • 系统兼容性:低电容特性有利于保持高速信号完整性,但在差分对应用时仍需做信号完整性验证以确认眼图与抖动满足要求。

五 封装与订购信息

  • 封装形式:SOT-143,两通道并列布局,适合自动贴装与回流焊。
  • 品牌:ElecSuper(静芯微)
  • 描述/型号:SR05-02CTG-ES(双路单向 TVS)
  • 订购建议:量产前请索取完整数据手册进行引脚定义、绝对最大额定值与典型波形验证;如需样片或可靠性测试数据,请与供应商联系。

以上为 SR05-02CTG-ES 的产品概述与应用建议。如需更详细的电气特性曲线、引脚定义或参考电路图,请提供联系信息或索取完整数据手册。

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
