BOURNS CDDFN10-0524P 静电放电(ESD)保护二极管产品概述

BOURNS CDDFN10-0524P是一款专为高速信号接口设计的多路TVS(瞬态电压抑制)二极管,聚焦“低信号干扰+高静电防护”双重需求,采用超小型DFN-10封装,广泛适配消费电子、汽车及工业领域的敏感电路防护场景。

一、产品核心定位

针对高速串行接口(如USB Type-C、HDMI、Gigabit Ethernet)及低功耗电子电路的静电放电(ESD)防护痛点,CDDFN10-0524P实现4通道同步防护,平衡“信号完整性”与“瞬态耐受能力”,尤其适合小型化、高频化的终端产品设计(如智能手机、车载IVI系统)。

二、关键电气性能参数

参数 典型值/额定值 说明 反向截止电压(Vrwm) 5V 正常工作时无漏电流干扰,适配3.3V/5V电源及信号电路 钳位电压(Vc) 12V(典型) 触发后快速将瞬态过压限制在12V以内,保护后端敏感器件 峰值脉冲电流(Ipp) 3.8A(8/20μs波形) 可吸收人体放电模式(HBM)、机器放电模式(MM)等常见ESD脉冲 峰值脉冲功率(Ppp) 30W 单次脉冲耐受能力强,避免器件因过压击穿 击穿电压(Vbr) 6V(典型) 触发阈值低,响应速度快(ns级) 反向漏电流(Ir) 1.5μA(@5V) 低漏电流确保电路静态功耗无额外负担,适合低功耗设计 结电容(Cj) 0.5pF(典型) 对10Gbps及以上高速信号的插入损耗/相位偏移影响极小,保障信号完整性 通道数 4路 单器件可同时防护4组信号/电源线路,简化电路设计

三、封装与物理特性

采用DFN-10(1×2.5mm) 超小型封装,具备以下优势:

  • 尺寸紧凑:长度2.5mm×宽度1mm×高度<0.8mm,适配智能手机、智能穿戴等便携式设备的小型化需求;
  • 引脚兼容性:符合回流焊工艺标准,支持自动化贴装(SMT),生产效率高;
  • 热性能:DFN封装散热面积大,可有效散发热量,避免脉冲放电后的器件过热。

四、主要应用场景

  1. 消费电子:智能手机、平板电脑、笔记本电脑的USB Type-C、HDMI、DisplayPort等高速接口,以及音频/视频端口的ESD防护;
  2. 汽车电子:车载信息娱乐系统(IVI)、ADAS传感器接口(摄像头、雷达)、车载USB端口的静电防护(支持-55℃~+85℃宽温);
  3. 工业控制:PLC、工业传感器、工业通信模块(如Profinet)的接口防护,适配工业级环境温度与电磁干扰;
  4. 通信设备:路由器、交换机的Gigabit Ethernet接口、光纤收发器端口的ESD防护。

五、符合标准与可靠性

  • 静电防护标准:完全符合IEC 61000-4-2 标准,支持接触放电±8kV、空气放电±15kV的防护等级;
  • 温度可靠性:工作温度范围-55℃~+85℃(Ta),满足汽车级(AEC-Q101兼容)及工业级环境的温度要求;
  • 机械可靠性:DFN封装具备良好的抗振动、抗冲击性能,适合车载、移动终端等振动场景。

六、选型与使用注意事项

  1. 极性识别:TVS为单向防护,需注意引脚极性(通常靠近器件标识端为阴极),正确并联在“被保护线路→地”之间;
  2. 焊接工艺:推荐回流焊温度(峰值260℃±5℃,时间<30s),避免手工焊接温度过高损伤器件;
  3. 并联扩展:如需更高防护电流,可多只器件并联,但需注意结电容叠加(每增加1只,Cj增加0.5pF);
  4. 降额使用:为提升可靠性,建议工作电压不超过Vrwm的90%,脉冲功率使用不超过Ppp的80%。

总结

CDDFN10-0524P凭借“多路同步、低电容、高防护、超小型”的核心优势,成为高速接口ESD防护的优选器件,覆盖消费、汽车、工业等多领域设计需求,平衡了性能与成本,适合量产应用。

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
