NUP2105L 产品概述
一 产品简介
NUP2105L 是友台半导体（UMW）推出的一款表面贴装型单向 TVS（二极管瞬态抑制器），封装为 SOT-23，专为 24V 直流系统与中低压信号线提供快速浪涌与静电保护设计。器件在 8/20µs 冲击条件下能承受高能脉冲并将过压钳制在安全范围内，适合工业控制、楼宇自控、仪器仪表等应用的浪涌与 ESD 防护需求。
二 主要特性
- 反向截止电压（Vrwm）：24V（适配 24V 直流系统）
- 击穿电压（Vbr）：32V（典型值）
- 钳位电压（Vclamp）：44V @ Ipp(8/20µs)
- 峰值脉冲功率：350W @ 8/20µs
- 峰值脉冲电流（Ipp）：8A @ 8/20µs
- 结电容（Cj）：约 30pF（对高速差分信号有一定影响）
- 反向漏电流（Ir）：15nA（在 Vrwm 条件下，低漏电）
- 符合 IEC 61000-4-2 / 4-4 / 4-5 等抗扰规范（ESD、EFT、Surge）
三 关键参数解读
- Vrwm=24V 表示器件在正常工作时对 24V 线路能保持高阻态；当电压超过 Vbr（32V）开始导通，从而将瞬态能量钳制到 Vclamp（约 44V）。
- 350W@8/20µs 与 Ipp=8A 表明在工业级浪涌试验下能吸收较大能量，适合电源输入端与易受雷击或开关冲击的场景。
- 30pF 的结电容适中，适合电源与低速信号线保护；对 GHz 级高速接口可能产生影响，选型时需注意。
四 典型应用
- 24V 工业控制电源防护（PLC、继电器驱动电源）
- 传感器节点、楼宇自控接口的抗浪涌/ESD 保护
- 串行/差分通信线的防护（在允许的电容范围内）
- 电源输入端、接口过压保护电路
五 封装与布板建议
SOT-23 小尺寸，便于贴装与批量生产。布板时建议：
- TVS 尽量靠近被保护的引脚/接口放置，走线最短最粗。
- 接地（GND）回流路径短且多铜（或铺铜），减小回路感抗。
- 对高速信号应评估 30pF 对信号完整性的影响，必要时选择低容型 TVS 或增加阻抗匹配措施。
六 使用注意事项
- NUP2105L 为单向 TVS，适合单端直流电源保护；若用于双向信号，需选择双向型号。
- 在高能浪涌场合应配合熔断/限流元件使用，以保护 TVS 自身与系统。
- 出货与焊接按 SMD 工艺规范进行，避免长时间高温回流超出器件应力范围。
NUP2105L 以其小封装、高能量吸收能力和低漏电特性，是 24V 及类似电压等级系统中实现可靠浪涌与静电保护的实用选择。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
