PESD36VS2UT 双路单向ESD防护器件产品概述

一、产品定位与核心功能

PESD36VS2UT是东沃(DOWO)推出的双路单向瞬态抑制二极管(TVS),专为敏感电子电路的瞬态过压防护设计,可有效抑制静电放电(ESD)、电快速瞬变脉冲群(EFT)、浪涌(雷击/电源浪涌)等干扰事件,避免后端电路损坏或性能异常,保障设备稳定运行。

二、关键电气参数解析

该器件核心参数针对性强,兼顾防护性能与电路兼容性:

  • 极性:单向,适用于单方向过压防护场景(如电源线路单向浪涌);
  • 反向截止电压(Vrwm):36V,正常工作时器件处于截止状态,不干扰电路信号传输;
  • 击穿电压(Vbr):40V,电压超过此值时器件快速导通,启动泄放机制;
  • 钳位电压(Vc):75V,导通后将过压钳位在75V以内,保护后端敏感电路;
  • 峰值脉冲电流(Ipp):6A,可承受的最大瞬态脉冲电流;
  • 峰值脉冲功率(Ppp):300W@8/20μs,符合标准浪涌波形的最大功率耐受能力;
  • 结电容(Cj):25pF,中等电容值,兼顾防护与信号完整性,适用于中等速率接口;
  • 反向漏电流(Ir):1μA,正常工作时漏电流极小,不影响电路功耗与稳定性。

三、防护能力与标准符合性

器件严格符合国际电磁兼容(EMC)标准,覆盖多场景干扰防护:

  • IEC 61000-4-2(ESD):可承受接触放电±8kV、空气放电±15kV(典型值),有效抑制人体/设备静电干扰;
  • IEC 61000-4-4(EFT):支持2kV/5kHz电快速瞬变脉冲防护,抑制高频瞬态干扰;
  • IEC 61000-4-5(浪涌):兼容1.2/50μs电压浪涌与8/20μs电流浪涌,对应300W功率能力,应对雷击或电源开关浪涌。

四、环境适应性与可靠性

  • 宽温工作范围:-55℃~+125℃,符合工业级与汽车级温度要求,可在极端环境(如高温工业现场、低温户外场景)下稳定工作;
  • 高可靠性封装:采用SOT-23封装,工艺成熟,耐温、耐湿性能优异,适合批量生产;
  • 长期稳定性:低漏电流(1μA)确保器件长期工作无额外功耗,击穿电压一致性好,防护性能稳定可靠。

五、典型应用场景

结合参数特点,该器件适用于以下场景:

  1. 工业控制接口:RS485、CAN总线、Modbus等通信接口的ESD/浪涌防护;
  2. 汽车电子系统:车载传感器(温度、压力传感器)、车载通信接口的瞬态干扰防护;
  3. 消费电子:机顶盒、路由器等设备的接口(如HDMI、USB辅助防护);
  4. 低电压电源线路:24V电源系统的单向浪涌防护;
  5. 物联网设备:智能传感器、无线模块的接口瞬态防护。

六、封装与选型优势

  • 小体积封装:SOT-23封装尺寸约1.6×2.9×1.1mm,适合高密度PCB布局,节省空间;
  • 双路集成:单器件支持两路信号/电源防护,减少元件数量,简化电路设计;
  • 匹配性强:36V截止电压适配24V系统(留有余量),25pF结电容兼容10Mbps以下速率接口(如RS485),兼顾防护与信号传输质量。

总结:PESD36VS2UT凭借高防护能力、宽温适应性、小封装双路集成等优势,成为工业、汽车、消费电子等领域敏感电路瞬态防护的可靠选择。

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
