ESD56151W05-2/TR 瞬态抑制二极管产品概述

一、产品简介

ESD56151W05-2/TR 是 WILLSEMI(韦尔)推出的一款单路、双向瞬态抑制二极管(TVS),封装为 SOD-323(TR:卷带供料),用于对电源线或信号线的瞬态过压、雷击和静电放电提供可靠保护。该器件在-40℃~+85℃工作温度范围内稳定工作,适用于工业、通信、消费电子等需要 5V 级别保护的场合。

二、主要电气参数

  • 钳位电压(VC):7.5 V(典型)
  • 击穿电压(Vbr):6.3 V(典型)
  • 反向截止电压 Vrwm:5 V
  • 峰值脉冲功率 Ppp:2.4 kW @ 8/20 µs
  • 峰值脉冲电流 Ipp:145 A @ 8/20 µs
  • 峰值反向电流 Ir:100 nA(在 Vrwm 条件下)
  • 结电容 Cj:400 pF(典型)
  • 通道数:单路;极性:双向
  • 符合标准:IEC 61000-4-5(雷击/浪涌)、IEC 61000-4-2(静电放电)

三、关键特性与优势

  • 高能量承受能力:2.4 kW@8/20µs 的浪涌钳位能力和 145 A 的峰值电流,可有效吸收大多数工业雷击和浪涌事件。
  • 低钳位电压:约 7.5 V 钳位,有助于在 5 V 系统中将被保护器件限制在安全电压范围内。
  • 双向保护:能同时抑制正负极性瞬态,适合对差分信号线或双向电源线的保护。
  • 小型封装:SOD-323 便于在空间受限的电路板上实现自动贴片安装(TR 卷带供料),适合批量制造。

四、典型应用场景

  • USB、串行接口、I/O 口与微控制器接口的过压/ESD 保护(适用于 5 V 等级系统)。
  • 通讯设备和终端的接口防护(考虑到结电容,适用于低速或容差较大的信号)。
  • 工业控制、仪表与楼宇设备的浪涌抑制与静电防护。

五、设计与布局建议

  • 靠近受保护端口或连接器布置:将 TVS 器件尽量靠近外部接口放置,以最小化导线/走线上的寄生电感,提升吸收瞬态能量的效率。
  • 注意结电容影响:Cj = 400 pF 较大,会对高速差分信号(例如高速 USB/HDMI/USB3.x)产生明显影响,建议在高速信号保护时评估信号完整性或选用低电容版本;对 5 V 电源和低速信号非常合适。
  • 考虑串联阻抗或滤波:在需要兼顾信号完整性的场合,可配合小阻值串联或 RC 滤波,以平衡保护与传输性能。
  • 散热与重复冲击:器件的峰值脉冲能力基于单次 8/20µs 波形,若遇到多次或长时间冲击,应评估热耗散与器件寿命,必要时采用并联或更高功率等级的保护方案。

六、封装与可靠性

  • 封装:SOD-323,适配表贴工艺,TR 表示卷带包装,便于 SMT 自动化装配。
  • 工作温度范围:-40℃ ~ +85℃,适合大部分商业和工业环境。
  • 符合 IEC 61000-4-5 与 IEC 61000-4-2 标准,能在常见的浪涌与静电环境中提供合格的防护性能。

七、注意事项

  • 在选型前请确认目标信号频宽与结电容对系统的影响;若用于高速接口,请进行仿真验证或选择低容 TVS。
  • 确认焊接温度曲线与 PCB 装配工艺,以避免封装和性能退化。
  • 若需要更高反复承受能力或更低钳位电压,可与供应商沟通替代型号或并联/级联方案。

总结:ESD56151W05-2/TR 以其 5 V 级别的稳压与高达 2.4 kW 的瞬态吸收能力,结合小型 SOD-323 封装,适合在空间受限且需对 5 V 电源或低速双向信号实施可靠浪涌与静电防护的应用场景。

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
