PTVSHC3D7VU 产品概述

一、产品简介

PTVSHC3D7VU 为 Prisemi(芯导)出品的一款单通道单向瞬态抑制二极管(ESD TVS),封装为 SOD-323。器件针对瞬态电压冲击和静电放电(ESD)保护而设计,提供快速钳位响应并满足工业级抗扰度测试标准,适用于对空间有严格要求的表面贴装保护方案。

二、主要技术参数

  • 钳位电压(Vc):25 V(典型钳位电压)
  • 击穿电压(Vbr):8 V
  • 反向截止电压(Vrwm):7 V
  • 峰值脉冲功率(Ppp):1.1 kW @ 8/20 μs
  • 峰值脉冲电流(Ipp):60 A @ 8/20 μs
  • 反向电流(Ir):1 μA(常温)
  • 结电容(Cj):500 pF
  • 通道数:单路;极性:单向
  • 类型:ESD(瞬态抑制二极管)
  • 防护等级:符合 IEC 61000-4-2(ESD)与 IEC 61000-4-4(EFT)规范
  • 品牌/型号:Prisemi(芯导) / PTVSHC3D7VU
  • 封装:SOD-323(表面贴装)

三、关键特性与优势

  • 快速响应:对静电放电和短时高能脉冲具有快速钳位保护能力,能在瞬间将多余能量导入地线,保护下游电路。
  • 高能量吸收能力:在 8/20 μs 波形下支持 60 A 峰值脉冲电流和 1.1 kW 峰值脉冲功率,适合常见突发浪涌场景。
  • 小型 SOD-323 封装:占板面积小,适用于体积受限的移动设备、便携仪器及各种 I/O 接口保护。
  • 低漏电流:反向漏电仅 1 μA,有利于低功耗电路的长期可靠工作。
  • 工业级兼容性:满足 IEC 61000-4-2 / 4-4 要求,可用于具备抗静电与快速瞬态抗扰要求的系统。

四、应用场景

  • 人机接口与外设接口保护:如按键、插孔、外部传感器接口等。
  • 通用信号线与电源线路的瞬态保护:适用于直流偏置或低频信号线(注意结电容限制)。
  • 消费类与工业电子设备的局部浪涌防护:仪表、控制模块、低速通信口等。

注意:由于结电容约 500 pF,本器件对高速差分或高带宽信号(例如 USB3.0、HDMI、PCIe 等)会造成信号失真或带宽下降,不建议用于高速信号线的直接保护。

五、典型电路接法

对于单向型号,建议按下列方式连接:将二极管阳极接地,阴极接被保护的信号线/电源线上(即常态为反向偏置)。在正常工作电压下二极管呈高阻抗;当瞬态电压超过 Vrwm 或击穿点时迅速导通,将过压钳位到 Vc 附近并导入地线,从而保护后端电路。若需要双向保护,应选用对应的双向型号或并联两只单向器件并注意封装和布局。

六、封装与可靠性提示

  • SOD-323 小封装适配常见贴片工艺,适于回流焊安装。
  • 在布局时应尽量缩短信号线到二极管的回流路径,确保低感抗接地回路,以提高吸收能量的效率。
  • 对于经常承受高能冲击的应用,建议增加外部限流或串联阻抗(如熔断器、PTC、阻性元件)以分担能量并提高系统可靠性。
  • 出厂或实际应用中请参考厂家完整的器件数据手册(包括温度特性、焊接曲线和管脚尺寸)以确认在极端工况下的性能。

七、选型与采购建议

PTVSHC3D7VU 适合需要单通道、单向保护且对板面空间敏感的低速信号及供电口。若应用涉及高速信号或需更低结电容,请选择专为高速接口设计的低容 TVS 器件。采购时请向正规代理或厂商索取最新器件规格书、RoHS/REACH 证明及样片测试数据,以确保参数满足具体应用需求。

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
