PTVSHC2EN5VB TVS瞬态抑制二极管产品概述

一、产品定位与核心价值

PTVSHC2EN5VB是芯导(Prisemi)推出的低电压瞬态抑制二极管(TVS),专为5V供电系统的过压防护设计,核心作用是快速抑制静电放电(ESD)、电快速瞬变脉冲群(EFT)等瞬态浪涌,保护敏感电子电路免受损坏。产品平衡了防护能力与电路兼容性,适配高密度小型化应用场景,是消费电子、IoT设备等领域的理想防护器件。

二、关键电气参数解析

2.1 瞬态浪涌防护能力

  • 反向截止电压(Vrwm):5V,精准匹配5V系统正常工作电压,不影响电路静态功耗;
  • 击穿电压(Vbr):典型值6.5V(范围5.5V),保证正常电压下处于截止状态,仅浪涌超过阈值时导通;
  • 钳位电压(Vc):提供9V、10V、12V、14V多档位(对应不同浪涌强度),将瞬态电压钳位在安全范围,避免后端电路过压;
  • 峰值脉冲参数:峰值脉冲电流(Ipp)10A@8/20μs(标准浪涌波形),峰值脉冲功率(Ppp)1.5kW@8/20μs,可承受常见ESD/EFT冲击(如HBM±8kV、MM±1kV)。

2.2 电路兼容性设计

  • 反向漏电流(Ir):典型值1μA(最大值2μA),漏电流极小,不影响5V系统静态功耗与信号完整性;
  • 结电容(Cj):260pF,适配中低速信号接口(USB 2.0、UART、I2C等),避免高频信号衰减(若需高速接口可搭配低容值TVS并联)。

2.3 国际标准认证

符合IEC 61000-4-2(ESD防护) 和 IEC 61000-4-4(EFT防护) 标准,经第三方测试验证,可有效抵御工业/消费场景电磁干扰,满足产品EMC要求。

三、封装与可靠性设计

采用DFN1610-2封装(尺寸1.6mm×1.0mm×0.5mm),具备三大优势:

  1. 小型化高密度:紧凑尺寸适配便携设备(智能手机、智能手表)的高密度PCB布局;
  2. 散热性能优异:暴露焊盘设计快速传导瞬态热量,避免器件过热损坏;
  3. 工艺兼容性:支持回流焊、波峰焊等常规SMT工艺,批量一致性好,抗机械应力能力强(适配车载等振动环境)。

四、典型应用场景

PTVSHC2EN5VB针对5V系统防护需求,典型应用包括:

  1. 消费电子便携设备:智能手机、平板电脑、智能手表的充电/数据接口(USB Type-C、Micro-USB)防护;
  2. IoT与智能家居:传感器节点(温湿度传感器)、智能家电(智能插座、扫地机器人)的通信端口防护;
  3. 小型电子模块:蓝牙/ WiFi/GPS模块的输入输出端口,防止静电/浪涌损坏射频电路;
  4. 低电压数字电路:5V供电单片机(STM32)、FPGA、LCD显示屏的I/O口防护,避免过压击穿。

五、品牌与品质保障

芯导(Prisemi)作为国内功率半导体领先厂商,PTVSHC2EN5VB具备:

  • 严格可靠性测试:经过-55℃~125℃温度循环、85℃/85%RH湿度测试、HBM 1000次ESD冲击等验证;
  • 环保合规:符合RoHS 2.0、REACH标准,无有害物质;
  • 批量一致性:成熟晶圆制造与封装工艺,参数离散性小,适合大规模量产。

该产品通过精准的参数设计与可靠的工艺保障,为5V系统提供高效、稳定的瞬态防护,是电子设备抗干扰设计的核心器件之一。

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
