ESD56161D24-3/TR 产品概述

一、产品简介

ESD56161D24-3/TR 是 WILLSEMI(韦尔) 出品的单路单向瞬态电压抑制二极管(TVS),封装为紧凑型 DFN2x2-3L,专为对 24V 等级电源/信号线提供快速浪涌与静电释放保护而设计。器件符合 IEC 61000-4-2、IEC 61000-4-4、IEC 61000-4-5 等抗干扰标准,适合工业与消费类电子的抗瞬态干扰场景。

二、主要参数(关键指标)

  • 极性:单向
  • 反向截止电压 Vrwm:24V
  • 击穿电压 Vbr(典型):25V
  • 钳位电压 Vc(典型):30V
  • 峰值脉冲电流 Ipp:170A(8/20µs)
  • 峰值脉冲功率 Ppp:5kW(8/20µs)
  • 反向电流 Ir:1µA
  • 结电容 Cj:700pF
  • 通道数:单路
  • 工作温度:-40℃ 至 +85℃
  • 防护等级:符合 IEC 61000-4-2/4-4/4-5

三、特点与优势

  • 高能量吸收:5kW(8/20µs)峰值功率与 170A 峰值电流能力,可应对工业级浪涌事件。
  • 快速钳位:典型钳位电压 30V,在 24V 系统中能有效限制过压幅度,保护下游元件。
  • 低漏电:1µA 的反向电流有利于降低静态功耗。
  • 小封装:DFN2x2-3L 体积小,利于空间受限的 PCB 布局。
  • 标准兼容:通过常见的 IEC 抗扰度测试,可靠性高。

四、典型应用

  • 24V 工业电源总线与分支保护
  • 接口保护:RS-485、CAN 辅助保护(注意结电容限制)
  • 电源输入、继电器驱动回路和小型逆变器前端保护
  • 工业控制设备、楼宇自动化、通信设备防雷电与静电场景

五、布局与安装建议

  • 器件应尽量靠近被保护的接口或电源引脚放置,走线尽量短直,减小回路电感。
  • 将器件阴极/接地端与设备地平面通过短而粗的走线或多过孔连接,必要时使用焊盘下的大焊盘/散热垫并辅以过孔散热。
  • 结电容 700pF 较大,会影响高速差分信号;若用于高速接口(USB/高速以太网等)需评估信号完整性或选用低容版本。
  • 在多通道应用中注意每通道的接地路径分离以避免耦合。

六、选型与注意事项

  • 对于严格的高速数据线保护,应优先考虑低 Cj 的 TVS;若保护对象为电源或低速信号,ESD56161D24-3/TR 是经济且高能的选择。
  • 工作温度范围为 -40℃~+85℃,用于更高温度环境需核实器件的长期热稳定性。
  • 选型时关注实际浪涌波形与能量,必要时在 PCB 上并联熔丝或限流元件以提高系统保护能力。

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
