DTESDBLC5V0LED02 H 产品概述

一、产品简介

DTESDBLC5V0LED02 H 是 CJ(江苏长电/长晶)出品的一款双向瞬态电压抑制(TVS)二极管,专为线路级静电放电(ESD)和瞬态浪涌保护设计。器件针对5V工作电压系统优化,封装为 WBFBP-02C,小型化适合贴片安装,可直接用于接口与信号线的保护。

二、主要电气参数

  • 钳位电压(Vc):10 V(峰值钳位)
  • 击穿电压(Vbr):8 V
  • 反向截止电压(Vrwm, 即反向工作电压):5 V(适合5V系统)
  • 峰值脉冲功率(Ppp):50 W @ 8/20 μs(单次脉冲能力)
  • 峰值脉冲电流(Ipp):5 A @ 8/20 μs
  • 结电容(Cj):约 12 pF(影响高速信号)
  • 反向漏电流(Ir):100 nA(典型)
  • 极性:双向(对称保护正负极两方向)
  • 类型:ESD 专用,符合 IEC 61000-4-2 防护等级
  • 封装:WBFBP-02C(小型贴片封装)

三、主要特性与优势

  • 双向结构:可保护交流或对地双向冲击的接口,无须额外极性判断,适用于差分线或双向信号。
  • 低钳位:典型钳位电压 10 V,能在冲击瞬间限制过电压,保护下游芯片。
  • 高脉冲能力:50 W(8/20 μs)和 5 A 峰值电流,可承受常见的静电和脉冲浪涌事件。
  • 低漏电与合理电容:100 nA 的低泄漏有利于功耗控制;12 pF 结电容在多数低速/中速接口中可接受,但需注意对极高速信号的影响。
  • 符合 IEC 61000-4-2:满足工业级 ESD 抗扰度要求,便于通过 EMC/ESD 相关测试。

四、典型应用场景

  • USB、UART、I2C、SPI 等 5V 或接近 5V 的接口保护
  • LED 驱动灯条、按键/触摸输入端防护(器件型号名含 LED,适合与 LED 驱动线路匹配)
  • 工控/通信设备的外部连接端口、信号线与接口板级保护
  • 消费类电子、车载子系统(非高温高功率主电源)中对瞬变浪涌的保护需求

五、封装与布局建议

  • 尽量靠近被保护的接口/引脚布置 TVS 器件,缩短走线长度以降低感性耦合与阻抗。
  • 建议器件端子采用直接回流焊或焊盘过孔短路径接地,地线应接在低阻抗的参考地或接地平面上。
  • 对于高速差分信号,注意 12 pF 的结电容会引入带宽限制或串扰,必要时评估信号完整性或选用低电容版本。

六、选型与注意事项

  • 适配工作电压:Vrwm=5 V 适合 5 V 系统,若工作电压高于 5 V 应选择相应 Vrwm 的器件。
  • 对高速接口(如 USB 3.0、HDMI、高速差分)使用前需评估 12 pF 对链路的影响;对极高速应用建议选择更低结电容器件。
  • 持续性和重复脉冲:Ppp 标定为单次脉冲能力,频繁或多次大能量冲击需评估器件寿命或采用多级保护策略。
  • 热管理与 PCB 设计:高能量脉冲会产生热量,保证器件周围有适当的散热路径和铜箔面积。

七、测试与合规

  • 器件设计满足 IEC 61000-4-2 标准的 ESD 抗扰能力,可用于通过相应的等级测试。
  • 推荐在产品开发验证阶段进行实际的 ESD、雷击波形(8/20 μs)和系统级耐受性测试,以确定保护效果与系统可靠性。

八、可靠性与使用建议

  • 在储存与贴装过程中应遵循常规焊接与静电防护规范(ESD-safe 作业)。
  • 对于长期暴露在高脉冲环境(如户外接口、工业现场)的应用,推荐在系统级进行加速老化或循环脉冲测试以确认使用寿命。
  • 若需更高的保护能力、低电容或专用车规级要求,应与供应商沟通替代型号或定制方案。

总结:DTESDBLC5V0LED02 H 是一款面向 5V 系统的双向 TVS 器件,具备 50 W/8/20 μs 的瞬态吸收能力、10 V 的低钳位电压和较低漏电,适合常见接口的线路级 ESD/浪涌防护。在布局、信号完整性和热管理方面的合理设计,将有助于发挥该器件的最佳保护效果。若需原厂数据表或更详细的测试曲线,建议联系 CJ 获取完整规格书。

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
