TPNUP2105LT1G 产品概述
一、产品简介
TPNUP2105LT1G 是 TECH PUBLIC（台舟电子）推出的一款双路双向瞬态电压抑制（TVS/ESD）器件，封装为 SOT-23。器件专为静电放电（ESD）和浪涌干扰防护而设计，适用于工业接口与消费类电子的输入/输出端保护，能在受扰动时快速钳位，保护下游电路不被破坏。
二、主要参数与性能
- 极性：双向（适合差分线或可正负切换的信号线）
- 反向截止电压 Vrwm：24 V（适用于 24 V 及以下工作电压的保护场景）
- 击穿电压 Vbr：约 26.7 V（器件进入受控导通区的起始电压）
- 钳位电压 Vclamp：约 43 V（在浪涌/冲击条件下对电压的钳位水平）
- 反向电流 Ir：80 nA（静态漏电流低，对精密电路干扰小）
- 结电容 Cj：25 pF（中等电容，对中低速数据信号影响有限）
- 通道数：双路（单封装内可保护两条信号线或一对差分线）
- 防护标准：满足 IEC 61000-4-2（ESD）与 IEC 61000-4-4（EFT）规范
三、典型应用场景
- 工业控制总线和传感器接口（24 V 工业现场总线的输入保护）
- USB、UART、RS-232/RS-485、CAN 等通信端口的过压/静电防护（需评估速率与电容影响）
- 消费类电子设备的外部连接器保护（比如充电口、外设接口）
- PCB 输入端与连线处的浪涌抑制和系统级保护
四、设计与布局建议
- 放置位置：尽量靠近受保护的连接器或线路入口处，缩短从源头到器件的走线长度以降低串扰和抑制效率损失。
- 地线与走线：为保证放电回路低阻值，器件附近应有良好地平面或低阻路径；避免高阻长回路。
- 串联元件：在某些设计中可与小阻值串联电阻或共模电感配合使用，以改善吸收能量能力与高频性能。
- 对高速信号：Cj=25 pF 对中低速信号影响可接受，但对极高速差分接口（如 USB3.x、PCIe 等）需评估时域/频域影响，必要时选择更低电容方案。
五、封装与可靠性
SOT-23 封装占板面积小、易于自动贴装，适合空间受限设计。器件通过 IEC 61000-4-2/4-4 等抗扰动测试，能在常见静电和脉冲干扰下提供有效保护，适合工业与民用场景的静电浪涌防护要求。
六、选型与应用提示
- 若系统工作电压接近或超过 24 V，应检查器件 Vrwm 是否满足系统安全裕度。
- 对于对信号完整性敏感的应用，优先评估结电容对波形的影响并做实际测试。
- 若需更高能量吸收或更低钳位电压，考虑并联或更高规格的 TVS 器件。
小结：TPNUP2105LT1G 以其双路、双向结构与小巧 SOT-23 封装，为 24 V 及以下系统提供了一种低漏电、能效稳健的静电与浪涌保护方案，适用于多种工业与消费电子接口的防护设计。

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.
