PTVS24VS1UR 产品概述

一、产品简介

PTVS24VS1UR 是 FUXINSEMI(富芯森美)推出的一款单向瞬态电压抑制二极管(TVS),专为对抗瞬态过压、浪涌和静电放电(ESD)而设计。器件采用 SOD-123 表面贴装封装,单路保护,适用于要求体积小、响应快、部署方便的中低压直流保护场景。

二、主要参数

  • 极性:单向(unidirectional)
  • 反向截止电压 Vrwm:24 V(反向工作电压/稳压点)
  • 击穿电压 Vbr:26.7 V(典型)
  • 钳位电压 Vclamp:38.9 V(在峰值脉冲电流 Ipp 下测得)
  • 峰值脉冲电流 Ipp:10.28 A(对应钳位电压测量点)
  • 峰值脉冲功率 Ppp:400 W(典型测试条件,测试波形通常为 10/1000 µs)
  • 反向漏电流 Ir:1 µA(在 Vrwm 条件下)
  • 通道数:单路
  • 防护等级/标准:符合 IEC 61000-4-2(ESD 抗扰度)
  • 封装:SOD-123(表面贴装,侧向引脚)

三、典型应用场景

  • 24 V 工业电源轨保护(PLC、传感器、工控模块)
  • 通信接口与数据线的浪涌与静电防护
  • 车载电子中对 24 V 较高电压回路的过压保护(需评估系统级要求)
  • 电源输入端、外部接口(插座/接头)以及靠近受保护器件的局部防护

四、封装与安装建议

  • 封装为 SOD-123,适合自动贴装与回流焊工艺;请按供应商推荐的回流曲线进行焊接,以避免过热损伤器件。
  • 单向器件在电路中需注意极性:器件体上有阴极(带)标记,带端接向高压/信号源方向,阳极接地或参考地。
  • 为获得最佳防护效果,应将 TVS 尽量靠近被保护的输入端/连接器放置,缩短走线,减小回路电感。
  • 热散布与 PCB 设计:SOD-123 为小封装,连续或频繁浪涌时需考虑 PCB 铜箔面积与散热,必要时在器件附近增加散热铜箔或热墩。

五、性能与可靠性提示

  • 该器件适用于瞬态脉冲能量吸收,不适合长时间承受超过 Vrwm 的持续过压;如需连续稳压,请选用稳压器或限流方案。
  • 额定 Ppp(400 W)通常基于标准脉冲波形(例如 10/1000 µs)测试,实际应用中脉冲形状与重复率会影响器件寿命与温升,设计时需留有裕量。
  • 反向漏电流小(1 µA),适合对静态功耗敏感的电路,但在高温条件下漏电会增加,应在可靠性验证中对温升进行评估。
  • IEC 61000-4-2 ESD 等级的符合性,意味着器件能有效抑制接触或空放电引起的高频尖峰,但系统级抗扰仍需配合良好的接地与布线策略。

六、订购信息与注意事项

  • 型号:PTVS24VS1UR,品牌:FUXINSEMI(富芯森美),封装:SOD-123。
  • 采购与样片申请时请确认器件完整型号与批次,若对最高脉冲能量、测试波形或封装标识有严格要求,建议向供应商索取详细数据手册与可靠性报告。
  • 在设计验证阶段建议做热冲击、ESD、以及多次脉冲寿命测试,确保在目标应用场景中的稳定性与可靠性。

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
