TPE4V5KHC-ES 产品概述

TPE4V5KHC-ES 是 ElecSuper(静芯微)推出的一款高能量、单路双向 ESD 防护器件,采用 SOD-323 封装,专为 3.3V 电源与靠近外部接口的防护场景设计。器件在极端环境下仍能提供可靠的瞬态浪涌吸收能力,适合空间受限且需高抗扰性的消费、通信与工业类电子设备。

一、主要电气参数一览

  • 极性:双向(Bidirectional)
  • 反向截止电压 Vrwm:4.5 V(适配 3.3V 电源防护)
  • 击穿电压 VBR:4.8 V
  • 钳位电压 Vclamp:14.5 V(在峰值脉冲条件下)
  • 峰值脉冲电流 Ipp:160 A
  • 峰值脉冲功率 Ppp:2.5 kW
  • 反向泄漏电流 Ir:≤1 μA(典型、在 Vrwm 条件下)
  • 结电容 Cj:330 pF(大容量)
  • 通道数:单路
  • 工作温度范围:-55 ℃ ~ +125 ℃
  • 抗扰等级:满足 IEC 61000-4-2(最高可达 30 kV 空气/接触放电)
  • 封装:SOD-323
  • 品牌:ElecSuper(静芯微)
  • 型号:TPE4V5KHC-ES

二、产品特性与优势

  • 高能量吸收能力:160 A 峰值脉冲电流与 2.5 kW 峰值功率能力,使器件可承受较大能量的 ESD 与浪涌事件,保护下游敏感芯片免受瞬态击穿或功能失效。
  • 双向保护:对正负极性瞬态均能提供对称保护,适合没有明确极性的电源或信号线(如某些电源总线或双向接口)。
  • 适配 3.3V 电源:Vrwm = 4.5 V,针对 3.3V 系统留有安全余量,常态下泄漏电流极低(≤1 μA),降低静态功耗。
  • 空间节省封装:SOD-323 小型化封装,适用于空间受限、需表贴安装的电路板设计。
  • 高容性器件:330 pF 的结电容适合电源类或低速信号的旁路/防护,但不适合对带宽敏感的高速差分信号线。

三、典型应用场景

  • 3.3V 电源轨的输入保护(模块、电源滤波节点)
  • 靠近外部连接器的总线防护(电源适配器、充电口、电池接口)
  • 工业控制设备与通信终端的入板 ESD 防护
  • IoT 终端与消费电子设备需要高抗扰性的电源保护 注意:由于结电容较大,不推荐用于 USB 2.0/HDMI/高速串行差分等对线间容性严格限制的高速信号线路上。

四、典型电路连接建议

  • 将 TPE4V5KHC-ES 横跨被保护电源线与地(或参考地)之间,确保 ESD 能量通过低阻抗路径导入地平面。
  • 对于靠近外部接口的 PCB 区域,应将器件放置在可能受击中的走线与接地平面之间,器件引脚到被保护节点之间走线尽量短且直。
  • 若用于某些对电容敏感的线路,可通过串联小电阻或使用差分隔离方案减小瞬态透传对信号的影响。

五、PCB 布局与可靠性建议

  • 尽量靠近接口或潜在放电点放置器件,减少走线感抗与感性串联。
  • 为提高吸收能量能力与热散逸,建议在器件下方与周围使用较大面积的地铜箔,并通过多条过孔与内层地相连,形成良好的热与电流回流路径。
  • 避免在器件到地的走线上串入过多感性元件,保持回路最短最直接。
  • SOD-323 为小封装,手工焊接或回流焊时注意温度曲线,避免过热导致封装或内部结构损伤。

六、选型与使用注意

  • 若目标线路对带宽或信号完整性敏感,应选择低结电容型 TVS 器件;TPE4V5KHC-ES 更适合电源与低速信号防护。
  • 在高能量多次冲击场景下,建议在系统层面结合屏蔽、接地与滤波等手段共同防护,以延长器件寿命并保证系统稳定性。
  • 工作温度覆盖 -55 ℃ ~ +125 ℃,可用于工业级环境,但在特殊苛刻环境(如汽车电磁兼容 AEC-Q100 要求)时,请与供应商确认具体资格与可靠性数据。

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
