TPE4V5KHC 产品概述

一、产品简介

TPE4V5KHC 是 TECH PUBLIC(台舟电子)推出的一款单路静电与浪涌保护二极管,采用 SOD-323 小型封装,专为 5V 类电路与接口提供快速、可靠的瞬态过压防护。器件符合 IEC 61000-4-2(ESD)与 IEC 61000-4-5(浪涌)等工业级抗扰度要求,适用于工业控制、消费电子以及通信设备的输入输出保护。

二、主要性能特点

  • 反向截止电压 Vrwm:4.5V,适配典型 5V 电源与信号线路。
  • 击穿电压(Vbr):4.7V,器件在接近工作电压时即可进入钳位状态,限制过压幅度。
  • 钳位电压 Vc:15V(峰值),在浪涌/脉冲事件时对后端电路提供有效电压限制。
  • 峰值脉冲电流 Ipp:160A(8/20µs 波形),峰值脉冲功率 Ppp:2.5kW(8/20µs),能承受强脉冲能量注入。
  • 反向漏电流 Ir:800nA,低漏电利于节能和保持系统静态性能。
  • 结电容 Cj:320pF,便于对电源或低速信号线的能量吸收(对高速差分信号需注意影响)。
  • 工作温度范围:-55℃ 至 +125℃,满足宽温度运行需求。

三、典型应用场景

  • 5V 电源线、系统电源防护;
  • 串行通信接口(低速 UART、I2C、SPI 等)静电与浪涌防护;
  • 电源输入端、外部适配器接口保护;
  • 工业现场总线低速信号线路保护;
  • 任何需在紧凑空间内实现高能量冲击抑制的场合。

四、使用建议与注意事项

  • 器件为单路单向 TVS,适用于正向工作电压为 4.5V 的系统,应用时请确认系统的最大工作电压与钳位需求匹配。
  • 将器件尽量靠近被保护的接口或器件放置,走线最短、阻抗最小,以获得最佳防护效果。
  • Cj = 320pF 较大,可能对高速差分信号(例如 USB 2.0 高速、HDMI 等)造成信号完整性影响,不建议用于高速数据线的直接并联保护。
  • 对于重复或长时间的高能量浪涌,建议结合限流元件(如保险丝、热敏电阻)提升整体可靠性。
  • 焊接与回流按 SOD-323 工程规范进行,避免高温长时间滞留导致性能退化。

五、封装与可靠性

  • 封装:SOD-323,小巧低矮,便于贴片安装与密集布局;
  • 防护等级:符合 IEC 61000-4-2(静电放电)与 IEC 61000-4-5(浪涌)测试要求;
  • 工作温度:-55℃ ~ +125℃,适应工业级环境与恶劣温度条件。

六、选型提示

  • 若系统工作电压在 5V 附近且需抗大能量浪涌(高于 100A 峰值能力),TPE4V5KHC 为合适选择;
  • 若要保护高速差分信号,应选择低结电容(Cj 远小于 320pF)的 TVS 器件;
  • 在要求更高持续能量承受能力或多通道保护时,考虑并联或选用更大封装与更高 Ppp 能力的器件。

TPE4V5KHC 以其紧凑体积、较高的峰值脉冲承载能力和工业级温度/抗扰能 力,为对体积与防护能力有平衡需求的 5V 系统提供了经济可靠的瞬态抑制方案。若需具体电气特性曲线、封装尺寸图或参考电路图,请提供联系方式以便获取详细资料。

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
