PESD2IVN24-TR-ES 产品概述

PESD2IVN24-TR-ES 是由 ElecSuper(静芯微)推出的一款双路双向瞬态电压抑制器(ESD 保护器件),采用紧凑的 SOT-23 封装,专为接口和信号线的静电放电及瞬态过电压保护设计。器件在满足 IEC 61000-4-2 标准的同时,兼顾低漏电与较高的峰值吸收能力,适用于多种消费类、工业与通信类电子产品的接口保护。

一、主要特点与优势

  • 双路双向保护:两路独立通道,可同时保护两条差分或单端信号线,适用于差分接口或多通道设计。
  • 工作耐受电压:反向截止电压(Vrwm)24V,适配常见 24V 以内工作电压的接口与电源侧保护。
  • 强力瞬态抑制能力:在标准 8/20 μs 脉冲下,峰值脉冲功率 Ppp 为 600W,峰值脉冲电流 Ipp 为 8A,能有效吸收由静电或开关瞬态引起的高能脉冲。
  • 低漏电:典型反向电流 Ir 为 1 μA,在待机或低功耗场景下对系统影响小。
  • 极低结电容影响:单路典型结电容 Cj 为 24 pF(测试条件下),对中低速信号线影响有限,适合多数接口保护需求。
  • 紧凑封装:SOT-23 小体积,便于高密度 PCB 设计与自动化贴装。
  • 行业防护等级:满足 IEC 61000-4-2 静电放电防护要求,提升系统抗扰度与可靠性。

二、电气参数摘要(关键值)

  • 极性:双向
  • 反向截止电压 Vrwm:24 V
  • 钳位电压(典型):48 V(测试条件下)
  • 峰值脉冲电流 Ipp:8 A
  • 峰值脉冲功率 Ppp:600 W @ 8/20 μs
  • 击穿电压:26.5 V
  • 反向电流 Ir:1 μA
  • 通道数:双路
  • 结电容 Cj(典型):24 pF
  • 防护等级:IEC 61000-4-2
  • 封装:SOT-23
  • 品牌:ElecSuper(静芯微)
  • 器件类型:ESD 抑制二极管

三、典型应用场景

  • USB、串口、PWM、CAN 等 I/O 接口的静电与瞬态保护(当接口工作电压 ≤ 24V 时推荐)。
  • 工业控制与工业以太网中对外部连线的过电压防护(需根据系统带宽评估结电容影响)。
  • 通讯设备的差分信号或多通道输入保护。
  • 消费类电子(显示器接口、遥控端口)以及其他需兼顾空间与防护性能的场合。

四、布局与使用建议

  • 布局:器件应尽量靠近受保护的接口或连接器端放置,走线尽量短且宽,减少串联电感与阻抗。
  • 地线处理:对地型保护时,应保证本地接地良好并尽量减少地环路;在多层板上,保护器附近应有连续的接地平面,并在器件附近布置过孔连接至地平面。
  • 焊盘与封装:推荐遵循 SOT-23 标准焊盘与回流工艺,-TR 表示卷带包装,便于自动化贴装。请参考器件数据手册的焊盘设计建议以获得最佳焊接可靠性。
  • 信号完整性:结电容 24 pF 对超高速(如 USB3.0、HDMI)可能造成一定影响,使用前务必评估系统带宽与通带失真;对高频敏感线路可考虑更低电容的替代器件。

五、可靠性与合规

PESD2IVN24-TR-ES 按照行业常见 ESD 抗扰度设计,并满足 IEC 61000-4-2 静电放电要求。器件典型漏电小、响应快、可在多次脉冲下保持稳定保护性能。具体的寿命、工作温度范围、焊接热循环与返修建议请参照 ElecSuper 提供的器件规格书与可靠性报告。

六、选型与订购说明

  • 型号:PESD2IVN24-TR-ES(TR 通常表示带卷带包装,适合贴片生产线)。
  • 在选型时请确认系统最大工作电压不超过 Vrwm(24 V),并根据接口速率评估 24 pF 结电容对信号的影响。
  • 若需 RoHS、AEC 或其它认证信息,请向供应商或厂商技术支持索取完整规格书与合规性文件。

总结:PESD2IVN24-TR-ES 以其双路双向保护、小封装、高能量吸收与低漏电的特点,是针对中低速数据线与电源接口进行静电及瞬态保护的实用选择。设计时注意布线与接地,参考器件规格书进行系统级验证,可有效提升产品的抗扰动能力与可靠性。

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
