ESD5621W15-2/TR 产品概述

一、简介

ESD5621W15-2/TR 是 WILLSEMI(韦尔)推出的一款单路、单向 TVS(二极管瞬态电压抑制器),用于对静电放电(ESD)和浪涌(Surge)事件提供快速钳位保护。器件封装为 SOD-323F,适合表面贴装自动化生产;型号后缀“/TR”表示卷装(Tape & Reel)供应,便于贴片机使用。

二、主要电气特性(典型/关键参数)

  • 钳位电压(Vc):31 V(峰值钳位,8/20µs 浪涌条件下)
  • 峰值脉冲电流(Ipp):45 A @ 8/20µs
  • 反向截止电压 Vrwm(工作电压):15 V(推荐连续工作电压)
  • 击穿电压 Vbr:18 V(典型击穿起始电压区间)
  • 反向漏流 Ir:≤100 nA(在 Vrwm 条件下)
  • 结电容 Cj:270 pF(影响高速信号的带宽)
  • 通道数:单路;极性:单向
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 符合防护标准:IEC 61000-4-2(ESD)、IEC 61000-4-5(浪涌)

三、产品特点与优势

  • 针对典型工业与消费类电源或信号线提供可靠的浪涌和静电防护,45 A @8/20µs 的处置能力能抑制常见雷击/浪涌事件的能量传递。
  • 单向结构适合正向浪涌钳位的电源轨及单向信号保护,反向漏流低,有利于长期漏电控制与功耗管理。
  • SOD-323F 小封装占板面积小,适合空间受限的移动设备、外设以及各类嵌入式控制板。
  • 兼容 IEC 标准测试,便于系统通过 EMC/ESD 认证。

四、典型应用场景

  • 直流电源轨(≤15 V)保护:如板载电源输入、适配器接口、通讯模块电源。
  • I/O 接口防护(非高速差分信号):如按键、电机控制信号、传感器线缆等,对结电容敏感的高速接口(USB、HDMI、LVDS)应慎用或另选低容型 TVS。
  • 工业控制与楼宇设备、家电控制板、通信设备防护点。

五、使用建议与布板注意

  • 器件应尽量靠近被保护端口放置,输入线与 TVS 之间走线最短以降低感抗与尖峰电压。
  • 为提高对大能量浪涌的耐受性,必要时可与熔断器、PTC 或串联电阻配合使用,共同分担能量。
  • 对高速信号链路(对时序和眼图敏感)需评估 270 pF 结电容对信号完整性的影响,如有影响请选用低电容型 TVS。
  • 考虑散热与焊盘设计,确保浪涌事件时热量能及时扩散,提升可靠性。

ESD5621W15-2/TR 以其可靠的钳位能力、符合 IEC 标准的防护特性以及小型封装,为多类中低压电源与信号线提供经济有效的瞬态保护解决方案。在设计选型时,请根据系统工作电压、信号带宽要求与浪涌能量等级综合评估是否匹配。

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
