PTVS6V0S1UR 产品概述

一、主要参数

PTVS6V0S1UR 是富芯森美(FUXINSEMI)推出的一款单路单向 TVS 瞬态抑制二极管,适用于对 5V 级别电源与信号线的浪涌与静电防护。关键电气与环境参数如下:

  • 钳位电压 (Vc):9.2 V(典型)
  • 工作温度:-55 ℃ ~ +150 ℃
  • 击穿电压 (Vbr):7 V
  • 反向截止电压 (Vrwm):6 V
  • 峰值脉冲功率 (Ppp):400 W @ 10/1000 μs
  • 峰值脉冲电流 (Ipp):38.8 A @ 10/1000 μs
  • 反向电流 (Ir):≤500 μA(@ Vrwm)
  • 防护等级:符合 IEC 61000-4-2(ESD)要求
  • 通道数/极性:单路 / 单向
  • 封装:SOD-123(贴片)

二、产品特性

  • 高能量吸收能力:在 10/1000 μs 波形下可承受 400 W 峰值脉冲功率,适合较长脉冲宽度的浪涌环境。
  • 低钳位电压:9.2 V 的典型钳位电压可在浪涌发生时有效限制被保护节点电压,降低下游器件应力。
  • 宽工作温度:-55 ℃ 至 +150 ℃,可满足工业级与汽车周边电子设备的温度要求(请留意车规认证要求)。
  • 小型贴片封装:SOD-123 便于在空间受限的 PCB 上布局与自动贴装。
  • 单向设计:适合对直流供电线和单向信号线进行防护(如 5V 电源、单向 IO)。

三、典型应用场景

  • 5V USB 电源与接口保护(注意 USB 数据线通常需要专用低电容 TVS)。
  • 板级电源输入防护(例如嵌入式主板、模块电源接口)。
  • 工业控制与传感器电源线保护(高能脉冲或感应浪涌场景)。
  • 通信接口的单向线路防护(如某些单端串口或控制信号线)。

四、设计与使用建议

  • 布局:TVS 器件应尽可能靠近被保护的接口或插头,走线短而粗,减小寄生电感。
  • 极性:单向器件在正常工作下以反向(Vrwm)承压,连接时确保阴极端朝向接地方向(参考封装标识)。
  • 热管理:虽然单个脉冲能量大,但不适合连续重复大能量冲击,必要时与熔断器或复位保险丝搭配使用以防器件自毁波及系统。
  • 考虑漏电:反向电流 ≤500 μA 对高阻电路或电池备用电路可能产生影响,敏感电路需评估漏电容忍度或选择漏电更低的型号。
  • 选型注意:若保护双向信号线(交流或差分)应选择双向 TVS;对高速数据线还需考虑器件电容与信号完整性影响。

五、封装与可靠性

SOD-123 封装适合自动贴装工艺,推荐按元件供应商的回流焊曲线进行焊接;长期在高温环境下使用时请参考厂商寿命与漂移数据。器件符合 IEC 61000-4-2 抗静电标准,能对常见的触摸静电事件提供保护;但不同系统的具体等级(KV 数值)请参考具体器件数据表以确认。

六、采购与注意事项

订购时请确认完整型号(PTVS6V0S1UR)、制造批号与包装数量;对关键应用建议索取并阅读完整数据手册与可靠性测试报告。使用前应在目标系统中做实际浪涌与信号完整性评估,确保钳位与漏电特性满足整体设计需求。若需替代或配合器件选型咨询,可提供系统工作电压与预期浪涌波形以获得更精确的建议。

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
