TPESD05LUS3 ESD防护器件产品概述

TPESD05LUS3是台舟电子(TECH PUBLIC)推出的一款针对低电压电路的静电放电(ESD)防护器件,主打小体积、低电容、宽温稳定,可有效抵御静电冲击及电快速瞬变脉冲群干扰,适配消费电子、工业控制等多领域的小型化设备防护需求。

一、产品核心定位

该器件聚焦低电压电路的“防护能力”与“信号完整性”平衡,针对3.3V/5V供电系统设计:既通过低结电容减少对高频信号的干扰,又具备足够的脉冲耐受能力,是小型电子设备接口与敏感电路的经济高效防护方案。

二、关键技术参数解析

2.1 防护核心参数

  • 反向截止电压(Vrwm):5V:适配主流3.3V、5V供电电路,正常工作时器件处于反向截止状态,漏电流仅1uA,不影响电路功耗与功能。
  • 击穿电压:6V:比截止电压高1V,可应对电路电压波动(如瞬态过冲),同时在静电冲击时快速击穿导通,泄放能量。
  • 峰值脉冲电流(Ipp):3A@8/20us:可承受8/20us波形(模拟人体放电模型HBM、机器放电模型MM的典型脉冲)的3A峰值电流,覆盖常见静电冲击场景。
  • 峰值脉冲功率(Ppp):150W@8/20us:对应脉冲能量耐受能力,满足IEC 61000-4-2等标准的防护要求。

2.2 信号兼容性参数

  • 结电容(Cj):0.6pF~1pF:低电容特性使其可用于高速信号传输线(如USB 2.0/3.0、HDMI、以太网接口),避免信号衰减、相位失真,保障数据传输完整性。

2.3 环境适应性参数

  • 工作温度:-55℃~+125℃:覆盖工业级温度范围,可在极端环境(高温车间、低温户外)下稳定工作,适配严苛应用场景。

三、封装与可靠性设计

TPESD05LUS3采用SOT-23封装,尺寸小巧(约2.9mm×1.6mm×1.1mm),适合智能手机、智能穿戴、小型工业传感器等对体积敏感的设备。封装引脚布局合理,焊接兼容性强,支持回流焊、波峰焊等常规工艺。

此外,器件通过IEC 61000-4-2(静电放电:接触放电±8kV、空气放电±15kV) 及IEC 61000-4-4(电快速瞬变脉冲群:±2kV/5kHz) 标准测试,可靠性符合工业级要求,可承受数千次静电冲击(典型值)。

四、典型应用场景

该器件的特性使其适用于以下场景:

  1. 消费电子接口:智能手机、平板、笔记本的USB、HDMI、音频接口防护;
  2. 工业控制电路:传感器输入输出端口、PLC数字量接口的静电防护;
  3. 通信设备:路由器、交换机的以太网端口、无线模块接口防护;
  4. 小型智能设备:智能手环、智能家居控制器的敏感电路防护。

五、使用注意事项

  1. 极性确认:TPESD05LUS3为单向防护器件,需核对丝印与引脚对应关系,避免反向安装导致防护失效;
  2. 安装位置:尽量靠近被防护端口/电路,减少引线长度,降低引线电感对防护效果的影响;
  3. 焊接工艺:焊接温度需符合SOT-23封装要求(如回流焊峰值温度≤260℃,时间≤10s),避免高温损坏器件;
  4. 电压匹配:确保电路工作电压不超过5V(反向截止电压),防止器件长期导通。

六、总结

TPESD05LUS3以小体积、低电容、宽温稳定为核心优势,兼顾防护能力与信号完整性,是3.3V/5V供电电子设备的高性价比防护选择,可满足消费电子、工业控制等多领域的静电防护需求。

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
