PTVSHC3D4V5BH 产品概述

一、产品简介

PTVSHC3D4V5BH 是 Prisemi(芯导)推出的一款单路瞬态抑制二极管(TVS),用于静电放电(ESD)与浪涌保护。器件采用 SOD-323 小型封装,适合空间受限的消费电子与工业接口防护,型号定位为对 5.1V 工作电压的电路提供高速脉冲保护。

二、关键参数

  • 类型:单路 TVS(瞬态电压抑制器)
  • 钳位电压(Vc):20V(典型)
  • 击穿电压(Vbr):4.6V
  • 反向截止电压(Vrwm):5.1V
  • 峰值脉冲功率(Ppp):2.7kW @ 8/20µs
  • 峰值脉冲电流(Ipp):160A @ 8/20µs
  • 反向漏电流(Ir):≤2µA
  • 结电容(Cj):≈300pF
  • 工作温度范围:-55℃ ~ +125℃
  • 防护等级:符合 IEC 61000-4-2(ESD)与 IEC 61000-4-4(EFT)
  • 封装:SOD-323

三、性能亮点

  • 高脉冲功率承受能力(2.7kW@8/20µs)和大峰值浪涌电流(160A),能有效吸收瞬态能量,保护下游器件。
  • 低漏电流(2µA),在待机或低功耗场景下对系统影响小。
  • SOD-323 封装体积小、热阻低,利于贴片化自动化生产与可靠焊接。
  • 满足 IEC ESD/EFT 标准,适合对接外部可接触接口的保护需求。

四、典型应用场景

  • USB、串口、低速信号线及5V系统电源轨保护。
  • 消费电子(手机配件、便携式设备)、工业控制模块与仪表中需局部防护的接口。
  • PCB 上靠近连接器的位置进行过压与静电泄放防护。

五、选型与布局建议

  • 由于结电容约为300pF,器件对高速差分信号(如高速 USB/HDMI)可能引入显著电容负载,建议用于电源线或对电容敏感性低的信号;高速链路应优先选择低电容型 TVS。
  • 器件应尽量靠近被保护的连接器或输入端放置,缩短走线并保证良好地线回流。必要时在 TVS 与关键器件之间增加串联阻抗(阻容或铁氧体)以改善浪涌能量分配。
  • 遵循厂商推荐焊盘及回流温度曲线,SOD-323 有利于常规 SMT 工艺。

六、可靠性与使用注意

  • 工作温度范围 -55℃ 至 +125℃ 满足工业级应用。长期在高温高能脉冲环境下使用,建议按系统热设计与循环应力考量余量。
  • 在反复高能冲击后,器件特性可能变化,关键系统应做整机级耐久性验证。

PTVSHC3D4V5BH 以其高能量承受能力、工业级温度范围和小巧封装,适合对 5V 级电路进行可靠的瞬态与静电防护。在选型时应结合系统对信号带宽、容性负载和功率吸收需求综合评估。

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
