IP4292CZ10-TBR.115 产品概述

IP4292CZ10-TBR.115 是 ElecSuper(静芯微)推出的一款四路单向 ESD 防护二极管阵列,针对 3.3V 信号接口和高频数据线的静电放电保护需求进行了优化。器件采用小型 DFN2510-10L 封装,单通道结电容低至 0.45 pF,具有快速响应、低钳位电压和高峰值脉冲承载能力,适用于要求高可靠性和高信号完整性的便携式、通信和消费电子产品。

一、主要特性

  • 极性:单向(单向 TVS,适用于带极性或带偏置的线路保护)
  • 工作反向截止电压 Vrwm:3.3 V(适配 3.3V 系统)
  • 钳位电压 Vc:典型 5 V(在峰值脉冲条件下提供低钳位电压,减少被保护器件应力)
  • 峰值脉冲电流 Ipp:8 A(常用 8/20 μs 测试波形)
  • 峰值脉冲功率 Ppp:40 W(短时脉冲能量吸收能力强)
  • 击穿电压 Vbr:7.3 V(器件进入导通状态的击穿点)
  • 反向静态电流 Ir:100 nA(在 Vrwm 下的低泄漏电流,有利于低功耗系统)
  • 通道数:四路(四通道独立防护)
  • 结电容 Cj:0.45 pF(低电容设计,最大限度降低对高速信号的影响)
  • 防护等级:符合 IEC 61000-4-2 ESD 标准(满足工业级静电放电防护要求)
  • 封装:DFN2510-10L(紧凑型表贴,利于 PCB 布局密度优化)

二、功能与优势

  • 低结电容:0.45 pF 的超低 Cj 非常适合 USB、MIPI、LVDS、I2C/SPI 等高速数据线,能在不显著降低信号带宽和完整性的前提下提供保护。
  • 低钳位电压:在遭遇 ESD 或脉冲干扰时,典型钳位电压约 5 V,可有效限制瞬态电压,保护后端敏感芯片。
  • 单向结构:适用于带正向工作偏置的电源或数据线,避免反向导通带来的误动作。
  • 四路集成:一颗器件即可保护多条信号线,节省 PCB 空间和器件数量,降低总成本。
  • 小型封装:DFN2510-10L 占板面积小,厚度低,适合便携式与空间受限的应用场景。
  • 符合 IEC 61000-4-2:满足常见静电放电试验规范,增强系统抗干扰能力和产品可靠性。

三、典型应用场景

  • 移动终端与便携式设备(针对 3.3V IO 与数据接口)
  • 消费电子:摄像头模组、显示驱动接口、触控控制器等
  • 通信设备:路由器、交换机、基站 RF 前端辅助线路(数据控制线)
  • 工业控制与仪表:现场总线、传感器接口与控制信号线
  • 汽车电子(非高压核心电源,需按照车规要求额外验证)

四、封装与 PCB 布局建议

  • 封装说明:DFN2510-10L,典型外形 2.5 mm × 1.0 mm,10 引脚,内部四路并行保护结构。
  • 布局建议:将器件尽可能靠近受保护的接口或连接器放置,以缩短走线并减小寄生电感与电阻,从而提高 ESD 能量传导效率。
  • 接地处理:提供低阻抗的 GND 回流路径,建议在器件 GND 引脚下方设计焊盘和多层过孔,连接到内层和底层大地平面,以便更好地散热和泄放脉冲能量。
  • 焊接工艺:适用于无铅回流焊工艺,注意控制温度曲线以保证可靠焊接。存储和贴装过程中应遵循防静电措施。

五、选型与使用注意事项

  • 匹配电压等级:Vrwm=3.3 V,适合 3.3 V 系统。如系统工作电压更高或需双向保护,请选用相应 Vrwm 或双向器件。
  • 热与能量预算:在设计中应估算可能遭受的脉冲能量和重复发生频率,若存在频繁大能量冲击,应考虑并联更高能量器件或增加串联阻抗/滤波元件以分担能量。
  • 环境与可靠性:器件的静态泄漏 Ir 随温度升高会增加,关键应用需在系统级进行温度和长期老化评估。
  • 测试条件:器件的 Ipp、Ppp、Vc 等参数通常基于标准脉冲波形(如 8/20 μs)测量,实际应用中应结合系统波形特性进行验证。

IP4292CZ10-TBR.115 以其低电容、低钳位、四路集成和小尺寸封装,适合对信号完整性要求高且需要多路保护的 3.3V 接口场景。选型时结合实际系统电压、瞬态能量和布局条件,可为产品提供可靠且低影响的瞬态过压保护。

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
