PESD24VS2UT-N 产品概述

一、产品定位与核心用途

PESD24VS2UT-N是伯恩半导体(BORN)推出的单向ESD防护器件,核心作用是为电子设备的信号线路、电源线路提供静电放电(ESD)、电快速瞬变脉冲群(EFT)及浪涌干扰的一体化防护,避免后端敏感元器件(如MCU、传感器、通信芯片等)因瞬态高压损坏。该器件适配消费电子、物联网、通信及工业控制等领域的小型化设计需求,是低成本、高可靠性的瞬态干扰防护解决方案。

二、关键性能参数解析

该器件的参数围绕“防护有效性”与“信号兼容性”平衡设计,核心指标解析如下:

  1. 极性与工作电压:单向防护设计,反向截止电压(Vrwm)为24V——正常工作时,反向施加电压≤24V时器件截止,不干扰信号;击穿电压30V,当电压超过30V时导通启动防护,避免后端器件击穿。
  2. 防护能力:峰值脉冲电流(Ipp)达6A(8/20μs波形,对应IEC 61000-4-5浪涌标准),峰值脉冲功率(Ppp)300W,可抑制强瞬态脉冲;钳位电压44V,导通后将浪涌电压钳位在44V以内,保护后端器件(多数敏感器件耐压远低于此值)。
  3. 信号兼容性:反向漏电流(Ir)仅500nA,低漏电流避免信号衰减或功耗增加;结电容(Cj)30pF,适合中等频率以下信号(如音频、低速数字信号、传感器数据),不影响信号完整性。
  4. 标准符合性:通过IEC 61000-4-2(ESD,接触放电±8kV/空气放电±15kV)、IEC 61000-4-4(EFT,±2kV/5kHz)、IEC 61000-4-5(浪涌,±2kV/1.2/50μs)三项核心电磁兼容标准,满足工业级与消费级设备抗干扰要求。

三、封装与典型应用场景

  1. 封装特点:采用SOT-23封装,尺寸仅约2.9×1.6×1.1mm,体积小、重量轻,可直接贴装PCB,适配高密度布线设计,满足电子设备“轻薄化”趋势。
  2. 典型应用:
    • 消费电子:智能手机、平板的USB接口、音频接口、按键线路防护;
    • 物联网设备:传感器节点、低功耗网关的信号输入/输出端防护;
    • 通信领域:基站辅助控制线路、无线模块的射频辅助接口防护;
    • 工业控制:小型PLC、远程IO模块的数字输入/输出口防护(满足工业级抗干扰)。

四、产品优势与应用价值

  1. 全场景防护:同时覆盖ESD、EFT、浪涌三种瞬态干扰,无需额外搭配其他器件,简化电路设计;
  2. 低干扰信号:低漏电流+合适结电容,平衡防护与信号完整性,避免影响设备正常功能;
  3. 小型化适配:SOT-23封装适配便携设备与高密度PCB,符合当前电子设备空间限制;
  4. 高可靠性:伯恩半导体成熟工艺,参数一致性好,长期工作稳定性高,降低设备返修率;
  5. 成本可控:性价比高于同类进口器件,适合中低端至中端设备批量应用。

五、选型与使用注意事项

  1. 极性匹配:单向防护需注意线路极性,确保防护方向与干扰方向一致(通常并联于信号/电源线路,反向接干扰源);
  2. 频率适配:若应用于超高频信号(如GHz级射频),30pF结电容可能导致信号衰减,建议搭配低结电容器件(如Cj<1pF);
  3. 电压匹配:正常工作电压需≤24V(Vrwm),避免器件误导通;若系统电压高于24V,需选择更高Vrwm的防护器件。

PESD24VS2UT-N凭借平衡的防护性能、小型化封装及高性价比,成为各类小型电子设备瞬态干扰防护的常用选择。

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
