TPESD0534P 产品概述

一、概述

TPESD0534P 是台舟电子(TECH PUBLIC)推出的一款四路低容抗静电/浪涌保护器件,采用 DFN2510-10 紧凑封装,针对低压高速信号线提供有效的过压与静电放电保护。器件以 Vrwm = 5V 的反向耐压为设计基准,适合 5V 及更低电压系统的保护需求,既能满足 IEC 61000-4-2(ESD)也能应对 IEC 61000-4-5(浪涌)测试要求。

二、主要参数

  • 反向截止电压(Vrwm):5 V
  • 击穿电压(Vbr):7.5 V(典型)
  • 钳位电压(Vc):15 V(典型,测试条件下)
  • 反向漏电流(Ir):500 nA(在 Vrwm 下)
  • 通道数:4 路
  • 结电容(Cj):0.4 pF / 0.2 pF(低容抗扰设计,利于高速信号完整性)
  • 类型:ESD / 浪涌保护器件
  • 封装:DFN2510-10(小尺寸,适合空间受限设计)
  • 符合标准:IEC 61000-4-2,IEC 61000-4-5

三、核心特性

  • 低结电容:典型 0.2–0.4 pF,最小化对高速信号的影响,适配高速数据接口。
  • 低漏电流:在 5 V 工况下 Ir 仅 500 nA,有利于电池供电与高阻抗设计。
  • 多路集成:四路保护减少 PCB 占用和外围器件数量,便于多信号线同时保护。
  • 小尺寸封装:DFN2510-10 节省板面空间,适合便携、移动终端与相机模组等应用。
  • 工业级兼容:设计满足 IEC 61000-4-2 与 IEC 61000-4-5 要求,具备较强的抗干扰能力。

四、典型应用场景

  • 移动终端与平板的外设数据线保护(USB、摄像头接口等)
  • 相机模组、MIPI/CSI 高速接口(需注意匹配具体速率和差分特性)
  • 工业控制与传感器信号线的浪涌与静电防护
  • 物联网节点、可穿戴设备及其他空间受限电子产品

五、封装与 PCB 布局建议

  • 器件靠近受保护接口或连接器放置,缩短受保护节点到器件的走线长度,减小环路感应。
  • 将器件的接地焊盘直接连至大面积接地平面,并在焊盘附近添加若干过孔(vias)导通至内部/下层地,以利于热量与瞬态能量快速散逸。
  • 避免在保护器与端口之间放置其它元件,若必须,优先使用小阻值串联电阻以降低浪涌能量传递。
  • 对于差分高速线,保持两线对称走线,尽量避免在器件附近形成不必要阻抗不连续。
  • 推荐遵循标准回流工艺焊接,确保焊点可靠。

六、选型与使用注意事项

  • Vrwm = 5 V 表明器件适用于 5 V 及以下逻辑电平保护;若为双向信号或更高电压,应选用对应规格的双向或更高 Vrwm 器件。
  • 钳位电压 15 V 为典型值,实际钳位效果与测试条件(脉冲电流、波形)相关,设计时应结合系统允许电压余量与下游元件耐压能力评估。
  • 虽然器件符合 IEC 标准,最终产品抗扰性能还取决于系统接地、屏蔽与整体布局。

七、总结

TPESD0534P 以其四路集成、低结电容、低漏电流与小型 DFN 封装,为需要在有限板面和对信号完整性敏感的场合提供了高效的静电与浪涌保护解决方案。正确的布局与配套设计能充分发挥其在移动设备、相机模组及各类高速接口的保护效能。若需更详细的电气特性曲线或封装与焊盘推荐图,请参考台舟电子产品资料或联系供应商获取完整技术手册。

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
