LXES1UTAA1-157 产品概述

一、产品简介

LXES1UTAA1-157 是 Leiditech(雷卯电子)推出的一款单路瞬态抑制二极管(TVS),用于抑制浪涌与脉冲干扰,保护敏感电子线路。该器件工作稳压(反向截止)电压为 5V,具有低结电容 0.22pF 和极低的漏电流 500nA,适合用于需保持高速信号完整性的 5V 系统和高速数据线保护场景。

二、主要电气参数

  • 反向截止电压 (Vrwm):5V
  • 击穿电压 (Vbr):6V
  • 钳位电压:12V(峰值)
  • 峰值脉冲功率 Ppp:110W(8/20μs)
  • 反向电流 (Ir):500nA
  • 结电容 Cj:0.22pF
  • 通道数:单路
  • 防护等级:满足 IEC 61000-4-5 标准
  • 封装:DFN1006-2(小型化表面贴装)

三、产品特点与优势

  • 极低结电容(0.22pF):对高速接口(如 USB、HDMI、LVDS 等)几乎无信号失真影响,适合高速数据线保护。
  • 低漏电流(500nA):利于电池供电或低功耗系统,降低静态能耗。
  • 中等钳位能力(12V)与 110W 峰值功率:能有效吸收典型的浪涌与雷击脉冲,保护下游器件不被过压损坏。
  • 小型 DFN1006-2 封装:适合空间受限的便携设备与紧凑 PCB 布局。
  • 符合 IEC 61000-4-5:具备工业级浪涌防护能力,适用于多种工业与民用场景。

四、典型应用场景

  • USB/数据接口保护(尤其 5V 系统)
  • 移动终端、便携设备的电源与数据线防护
  • 工业控制和通信设备的输入/输出端口浪涌防护
  • 智能家电、物联网节点的接口保护

五、设计注意事项

  • 布局:器件应尽量靠近被保护引脚并缩短到接地面的走线长度,以降低寄生电感和提高抑制效果。
  • 散热:虽然 DFN 小封装热阻较低,但在频繁或高能脉冲环境下需注意 PCB 散热与焊盘过孔布置。
  • 额定使用:遵循 8/20μs 脉冲能量规范,避免长期超出 Ppp 额定值工作。
  • 极性与方向:在单向保护应用中按厂商推荐方向焊接;对双向线路请确认型号支持或使用相应双向 TVS。

如需器件原理图引脚连接建议、封装尺寸图或更详细的电气特性曲线(I-V、钳位特性),可提供进一步资料以便设计验证与样板测试。

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
