TESD05EB 产品概述

一、产品简介

TESD05EB 是 Leiditech(雷卯电子)推出的一款小型双向瞬态电压抑制(TVS)二极管,用于对敏感电子线路提供瞬态过电压和静电放电(ESD)保护。器件工作电压(反向截止电压 Vrwm)为 5V,钳位电压约 12V,峰值脉冲功率为 100W(8/20μs 波形),单路双向结构,封装为超小型 SOD-523,特别适合对空间和寄生电容要求严格的高速接口防护场合。

二、主要参数一览

  • 类型:双向 TVS(单路)
  • 工作电压 Vrwm:5V
  • 钳位电压:12V(典型值)
  • 峰值脉冲功率 Ppp:100W @ 8/20μs
  • 反向电流 Ir:1 μA(常温下)
  • 结电容 Cj:15 pF(典型)
  • 工作温度:-55℃ ~ +125℃
  • 封装:SOD-523
  • 防护等级 / 兼容标准:IEC 61000-4-2(ESD)、IEC 61000-4-4(EFT)、IEC 61000-4-5(浪涌)

三、主要特性与优势

  • 小尺寸封装(SOD-523):适合高密度 PCB 设计与微型终端设备安装。
  • 双向保护:对互相对称的正负瞬态电压均能抑制,适用于差分信号线或对称电源应用。
  • 低结电容(15 pF):对高速信号线(如 USB、串行总线、传感器信号)影响小,能较好地保持信号完整性。
  • 高瞬态功率吸收能力(100W @ 8/20μs):能抵御常见的浪涌与脉冲干扰。
  • 宽工作温度范围与低漏电流(1 μA):适应工业级和车规级温度应力,且对低功耗系统影响小。
  • 满足 IEC 61000-4-2/-4/-5 标准:具备 ESD、EFT 与浪涌防护能力,便于系统级认证。

四、典型应用场景

  • 移动终端与可穿戴设备的接口保护(数据线、充电端口)
  • 工业控制器与传感器接口(现场总线、模拟/数字信号线)
  • 通信与网络设备的差分信号保护
  • 汽车电子中对低压信号线的抗干扰保护(在符合温度与可靠性要求的前提下)
  • 消费类电子、物联网节点等对空间要求高且需具备 ESD 防护的场合

五、使用要点与选型建议

  • 若被保护线为高速差分信号,优先选择低结电容 TVS(此器件 Cj≈15pF),以减小对信号速率的影响。
  • 确认被保护系统工作电压不超过 Vrwm(5V),以避免器件处于导通区影响正常工作。
  • 参考系统可能出现的最大浪涌能量与脉宽,确认 100W(8/20μs)能力是否充足;对更高能量场合可并联或选用更高能量等级器件。
  • 注意 PCB 布线:TVS 与被保护端尽量靠近,回流路径尽量短且阻抗低,以提高抑制效率并减小寄生感抗。
  • 考虑封装与焊接工艺的热应力,SOD-523 为小型表面贴装,需按厂商推荐的回流曲线加工。

六、可靠性与合规

TESD05EB 在设计上兼顾工业级工作温度(-55℃ ~ +125℃)与极低漏电流,满足常见的系统可靠性要求。器件通过或符合 IEC 61000-4-2(静电放电)、IEC 61000-4-4(快速瞬变脉冲群)及 IEC 61000-4-5(浪涌)的防护规范,便于整机通过相应的电磁兼容测试。

七、小结

TESD05EB 是一款面向空间受限且对信号完整性要求较高场合的双向 TVS 保护器件,具有低结电容、较高瞬态能量吸收能力与工业级温度范围,适用于移动设备、通信接口与工业传感器等领域。在选型和布局时,应关注工作电压、脉冲能量需求与 PCB 设计细节,以发挥其最佳保护效果。若需更高能量或更低电容的型号,可根据具体应用进一步比选或与供应商沟通获得器件数据手册与样片评估。

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
