NUP2105L 产品概述
一、产品简介
NUP2105L 是 DOWO（东沃）推出的一款双路、双向瞬态抑制二极管（TVS），采用 SOT-23 小体积封装，专为线路级 ESD 和浪涌保护设计。器件在设计上兼顾高速信号完整性与高能量吸收能力，适用于通信接口、数据总线、电源接口及汽车电子等领域。
二、主要电气参数
- 反向额定电压 Vrwm：24V
- 击穿电压 VBR(min)：26.7V
- 钳位电压（典型）：约 43V（瞬态峰值钳位可达 50V）
- 峰值脉冲功率 Ppp：420W（8/20μs 标准，SOT-23 封装在特定条件下可达约 450W）
- 峰值脉冲电流 Ipp：8A
- 反向漏电流 Ir：≤200nA
- 结电容 Cj：30pF（典型）
- 工作温度范围：-55℃～+125℃
三、抗扰等级与可靠性
NUP2105L 满足多项国际抗扰标准，包含 IEC 61000-4-2（静电放电）、IEC 61000-4-4（脉冲群）、IEC 61000-4-5（浪涌），能有效提高系统对外界瞬态干扰的鲁棒性，延长终端设备寿命。
四、产品特点与优势
- 双路双向保护，节省 PCB 空间并简化外接元件布线；
- SOT-23 小封装，适配空间受限的消费类与嵌入式设备；
- 低结电容（约 30pF），对高速信号干扰小，适合数据线保护；
- 低漏电流，满足对功耗敏感系统的要求；
- 宽温范围与高可靠性，适配工业与汽车级应用环境。
五、典型应用场景
- USB、HDMI、LAN 等高速接口的 ESD 与浪涌保护；
- 汽车车载总线、传感器信号线保护；
- 工业控制设备、仪器仪表及移动设备的输入/输出端防护。
六、选型与使用建议
- 若保护对象为 24V 额定线路，NUP2105L 可提供有效双向防护；
- 对于对钳位电压极为敏感的电路，应在 PCB 设计时预留足够裕量并评估钳位后的能量分配；
- 在高频高速信号线上，建议结合布局优化以降低寄生电感对钳位性能的影响。
综上，NUP2105L 以其紧凑封装、高能量吸收能力和符合 IEC 抗扰标准的特性，适用于多种需要稳健瞬态保护的应用场合。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
