韦尔ESD56241D15-3/TR 静电浪涌保护器件产品概述

韦尔半导体(WILLSEMI)推出的ESD56241D15-3/TR是一款单向单路TVS/ESD复合型防护器件,专为电子设备的静电放电(ESD)和浪涌脉冲防护设计,兼顾小型化封装与高防护能力,广泛适配消费电子、工业控制、物联网终端等领域的单通道线路防护需求。

一、核心身份与典型应用场景

ESD56241D15-3/TR定位为低速信号/电源线路的集成防护器件,核心属性明确:

  • 类型:TVS(瞬态抑制二极管)与ESD防护二合一,可同时应对ESD脉冲和浪涌干扰;
  • 通道数:单路设计,适合单电源线路、单数据总线、单传感器接口等单通道防护场景;
  • 品牌背书:韦尔半导体是国内功率器件头部厂商,产品可靠性经市场长期验证。

典型应用举例

  1. 消费电子领域:智能手机3.5mm耳机接口、Type-C充电口(单路电源防护)、智能手表电池充电线路;
  2. 工业控制:PLC(可编程逻辑控制器)数字输入/输出口、工业温度传感器电源线路;
  3. 物联网终端:智能门锁指纹传感器线路、智能家居灯泡电源接口。

二、关键电气参数深度解析

参数针对12V左右低速线路优化,边界清晰,核心指标意义明确:

1. 电压防护核心参数

  • 反向截止电压(Vrwm)15V:器件正常工作时反向偏置的最大允许电压,适配12V电源线路(留3V余量,避免正常波动触发防护);
  • 击穿电压(Vbr)17.3V:线路电压超过此值时器件反向击穿导通,泄放多余电流保护后端IC,避免误触发;
  • 钳位电压(Vc)29V:浪涌脉冲到来时,器件将线路电压钳位在29V以下(远低于多数IC耐压值),是防护有效性的核心指标。

2. 电流与功耗参数

  • 峰值脉冲电流(Ipp)160A@8/20us:可承受的最大浪涌电流(符合IEC 61000-4-5标准的8/20us波形),足以应对雷击感应、电源开关浪涌;
  • 反向漏电流(Ir)100nA:正常工作时漏电流极小,几乎不增加线路功耗,也不会导致后端IC误触发。

3. 结电容与应用边界

  • 结电容(Cj)1250pF:适合低速信号(如音频、1Mbps以下数据),对高速信号(USB3.0以上)会造成信号衰减,需避免使用。

三、封装与可靠性设计

采用DFN2x2-3L封装,兼顾小型化与可靠性:

1. 封装优势

  • 体积紧凑:2mm×2mm×0.7mm(典型厚度),适配智能手机、智能手表等小型化设备的高密度贴装;
  • 散热优异:DFN(无引脚扁平封装)通过焊盘直接散热,热阻远低于传统SOT-23封装,可承受大电流脉冲不失效;
  • 贴装兼容:支持标准SMT工艺,与自动贴片机兼容,降低生产难度。

2. 可靠性保障

  • 标准符合性:符合IEC 61000-4-5浪涌标准,同时满足ESD防护的人体放电模型(HBM≥±15kV);
  • 长期稳定性:漏电流仅100nA,长期工作无发热,参数漂移极小,适配工业级7×24小时运行;
  • 环保适配:符合RoHS标准,无有害物质,满足全球市场需求。

四、场景适配与选型建议

适配场景

  • 电源电压≤15V的单路电源线路;
  • 信号速率≤1Mbps的低速数据/音频线路;
  • 单通道接口(耳机、单传感器、单充电口)防护。

不适用场景

  • 高速信号线路(USB3.0、HDMI、以太网);
  • 双向信号线路(需双向ESD器件);
  • 电源电压>15V的线路(需更高Vrwm器件)。

五、产品总结

ESD56241D15-3/TR是一款高性价比单路防护器件,核心优势:

  • 紧凑封装适配小型化设备;
  • 160A浪涌电流能力应对强干扰;
  • 100nA漏电流保障线路稳定性;
  • 明确低速/15V线路的应用边界。

该器件已广泛应用于消费电子、工业控制、物联网等领域,是单通道线路防护的可靠选择。

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
