PTVSHC3N24VUH 产品概述

一、产品简介

PTVSHC3N24VUH 是 Prisemi(芯导)推出的一款单路瞬态抑制二极管(TVS),专为静电放电(ESD)、电快速瞬变(EFT)和雷击/浪涌(Surge)等瞬态过压事件提供保护。器件采用 DFN-3 (2×2 mm) 小封装,适合高密度布板与自动贴装生产,适配工业级 24V 直流系统及类似应用的过压防护需求。

二、主要性能参数

  • 反向工作电压(Vrwm):24 V
  • 击穿电压(V(BR)):典型 27 V
  • 钳位电压(Vclamp):典型值 34 V ~ 40 V(随脉冲电流级别变化)
  • 峰值脉冲电流(Ipp):140 A @ 8/20 µs
  • 反向漏电流(Ir):1 µA(在 Vrwm 条件下)
  • 结电容(Cj):约 800 pF(较大,需要在高频信号线路上慎用)
  • 通道数:单路
  • 防护等级与标准:符合 IEC 61000-4-2(ESD)、IEC 61000-4-4(EFT)、IEC 61000-4-5(Surge)

三、封装与机械特性

  • 封装:DFN-3,外形尺寸约 2.0 × 2.0 mm
  • 适合表面贴装(SMT)工艺,底部设有散热焊盘以提升能量耗散能力
  • 小体积利于空间受限设备的布局

四、应用场景

PTVSHC3N24VUH 非常适合用于需要 24V 直流保护的场合,例如:

  • 工业控制与自动化设备的信号线与电源防护
  • 通信与接入设备的电源入口保护
  • 电源适配器、PoE 辅助线路(需考虑结电容影响)
  • 仪表与测控终端的浪涌与静电防护

五、设计与使用建议

  • 布局:将 TVS 器件尽可能靠近受保护连线或接口放置,缩短导线与走线长度以降低感抗,尽量直接接地或接至公共参考地。
  • 接地:为获得最佳防护效果,建议使用较低阻抗的接地平面或地线,避免长回流路径。
  • 对高频信号:器件结电容约 800 pF,可能对高速数据线造成信号畸变,不建议直接用于对带宽敏感的高速差分信号(如 USB3.x、千兆以太网等)。
  • 热与功率:在高能冲击场景下注意 PCB 散热,必要时留凉铜或加大焊盘面积以提升脉冲能量吸收能力。
  • 配合元件:在对抗大量连续脉冲或特殊浪涌时,可与串联阻抗、共模电感或熔断器等配合使用以分担能量和限制电流。

六、可靠性与合规

该型号面向通过 IEC 61000-4 系列抗扰度要求的应用场景设计,能在常见的静电放电、脉冲群与浪涌事件中提供有效钳位与钳位能量吸收能力。建议在产品验证阶段结合系统级 EMC 测试,依据具体应用调整保护布置与器件选型。

七、订购信息与替代

  • 型号:PTVSHC3N24VUH
  • 品牌:Prisemi(芯导)
  • 封装:DFN-3 (2×2)
    如需更低结电容或更高/更低工作电压的保护器件,可参考同系列或其它型号以满足特定信号完整性与保护能量需求。

如需电路示例、PCB 布局建议或与具体系统兼容性评估,请提供目标应用的电气参数与拓扑,以便给出更详细的工程建议。

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
