NUP2105 产品概述

一、产品简介

NUP2105 是 SHIKUES(时科)推出的一款双路双向 ESD/瞬态电压抑制(TVS)保护器件,采用 SOT-23 小封装,专为空间受限的电子设备提供可靠的静电放电与浪涌防护。器件适用于工业现场、通信接口和电源线等需抗干扰的场合,能在恶劣环境下长期稳定工作。

二、主要参数

  • 钳位电压(VCL):44 V
  • 工作温度:-40 ℃ ~ +125 ℃
  • 击穿电压(Vbr):32 V
  • 反向截止电压(Vrwm):24 V
  • 峰值脉冲功率(Ppp):350 W @ 8/20 μs
  • 峰值脉冲电流(Ipp):8 A @ 8/20 μs
  • 反向电流(Ir):100 nA(常温)
  • 结电容(Cj):30 pF(典型)
  • 通道数:双路,极性:双向
  • 防护等级:符合 IEC 61000-4-2/-4-4/-4-5 等抗静电与浪涌标准
  • 封装:SOT-23

三、核心特性

  • 双路双向结构,可同时保护两条差分或独立信号线,省去外加反向二极管的设计复杂度。
  • 高能量吸收:350 W@8/20 μs 的能量处理能力,能承受工业级浪涌与脉冲干扰。
  • 低泄漏与快速响应:100 nA 的低反向电流与 TVS 器件固有的纳秒级响应,确保在异常瞬态下迅速钳位,保护后级电路。
  • 小尺寸、低成本:SOT-23 封装适合紧凑电路板,可直接靠近被保护端口布置,提升防护效率。
  • 适中结电容(30 pF),在多数接口上不会引入过度负载,但在超高速差分信号(如高速 USB/HDMI)需评估对信号完整性的影响。

四、典型应用

  • 工业自动化与控制系统(24 V 电源线保护、I/O 口防护)
  • 通信接口与传感器线路防护(RS-232/RS-485/CAN 总线等)
  • 消费电子与仪表的外部接口(按键、接口面板)
  • 需要符合 IEC ESD/浪涌规范的设备前端保护

五、布局与使用建议

  • 器件应尽可能靠近受保护的连接器或信号入口放置,尽量缩短输入线与器件之间的走线。
  • 将器件的公共接地(GND)通过短、低阻抗路径接到系统地或接地平面,必要时增加过孔直连多层地。
  • 对高速信号,注意结电容对信号带宽的影响;如有严格信号完整性要求,可选择更低 Cj 的保护器件或调整拓扑。
  • 在高能量环境中,合理评估散热与热阻,保证器件在脉冲条件下不会超过温度极限。

六、可靠性与合规

NUP2105 满足 IEC 61000-4-2(ESD)、IEC 61000-4-4(EFT)与 IEC 61000-4-5(浪涌)等工业级抗干扰标准,工作温度范围宽,适合长期在-40 ℃ 到 +125 ℃ 环境下运行。对于需要稳定防护、低成本和小封装方案的设计,NUP2105 是一款实用的选择。

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
