NUP2105LT1G 产品概述

一、产品简介

NUP2105LT1G 是 GOODWORK(固得沃克)推出的一款双向瞬态电压抑制器(TVS),采用 SOT-23 小尺寸封装,专为接口防护设计。该器件对静电放电(ESD)、射频瞬变与浪涌具有良好抑制能力,适合移动设备、通信接口、工业控制等需要抗干扰保护的场合。

二、主要参数

  • 极性:双向(Bi‑directional)
  • 反向截止电压 Vrwm:24 V
  • 击穿电压 Vbr:26.7 V(典型)
  • 钳位电压 Vclamp:40 V(峰值)
  • 峰值脉冲电流 Ipp:8 A
  • 峰值脉冲功率 Ppp:350 W(脉冲条件下)
  • 反向电流 Ir:100 nA(在 Vrwm 条件下)
  • 结电容 Cj:20 pF(典型)
  • 工作温度范围:-55 ℃ 至 +125 ℃
  • 防护等级/符合 标准:IEC 61000-4-2(ESD)、IEC 61000-4-4(EFT)、IEC 61000-4-5(浪涌)
  • 封装:SOT-23
  • 类型:ESD/瞬态保护二极管

三、核心特性与优势

  • 小体积封装:SOT-23 适合空间受限的 PCB 布局,便于自动贴装与回流焊工艺。
  • 双向保护:对正负脉冲均能有效钳位,适用于交流接口或双向信号线(如数据线、差分对等)。
  • 低漏电流:100 nA 的反向漏电保证在待机与低功耗电路中不会显著增加静态损耗。
  • 中等结电容:20 pF 的结电容在多数接口应用中兼顾了保护效果与信号完整性,适用于 USB、串行通信等中速信号线。
  • 高脉冲吸收能力:8 A 峰值脉冲电流与 350 W 峰值功率(脉冲条件)能应对常见的静电与浪涌事件,提升系统可靠性。
  • 宽温度范围:适应工业级环境,工作温度覆盖 -55 ℃ 到 +125 ℃。

四、典型应用

  • 手机、平板与便携式设备的外部接口保护(耳机孔、充电/数据口)。
  • 通信设备的串行/并行接口保护(RS‑232/RS‑485、USB、Ethernet 辅助线路)。
  • 工业控制与传感器接口的浪涌与脉冲抑制。
  • 电源线或低压总线的附加防护(非直接代替主电源保护器件)。

五、选型与使用建议

  • 根据工作电压选择:Vrwm 为 24 V,适用于 24 V 及以下连续工作环境;若系统连续工作电压靠近该值,应考虑留有一定裕量。
  • 钳位电压注意:在脉冲事件中器件钳位至约 40 V,确保下游器件能承受该短时电压或配合限流电阻/滤波器协同保护。
  • 信号完整性:Cj=20 pF 在高速差分信号(若超过数百 Mbps)可能影响串扰与上升沿,应在原理图与布线时评估并测试。
  • 布局要点:将 TVS 器件尽量靠近受保护的连接器或输入引脚放置,走线最短且直接接地,地线采用尽量低阻抗的接地平面。
  • 热与能量管理:350 W 为脉冲功率额定,不等于连续耗散能力。若可能遭受重复大能量脉冲,应增加限流元件或选择能量吸收更高的保护方案。

六、封装与可靠性

SOT-23 封装兼顾体积与散热,适合批量生产。器件经过 IEC 61000‑4 系列测试认证,能满足工业与消费类产品对抗静电、射频瞬变和浪涌的典型要求。推荐在实际系统中进行整机级的抗扰度验证,以确认在真实工况下的保护效果与可靠性。

总结:NUP2105LT1G 提供了低漏电、双向保护与中等结电容的良好平衡,适合多种需要电气瞬态防护的接口应用。在布线与热管理上注意合理布局与限流设计,可显著提高整机的抗干扰能力与可靠性。

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
