LM-ULC332010T8 产品概述
一、产品简介
LM-ULC332010T8 是 Leiditech（雷卯电子）推出的一款双路 ESD 保护二极管阵列，封装为 DFN2010-8，专为保护两对（四根）数据线而设计。器件采用直通式设计以简化 PCB 布局，针对 3.3V 工作电压的高速接口提供高效浪涌和静电防护，同时对信号完整性影响小。
二、关键参数
- 反向截止电压 (Vrwm)：3.3 V
- 钳位电压：12 V
- 击穿电压 (VBR)：8 V
- 峰值脉冲电流 (Ipp)：30 A @ 8/20 μs
- 峰值脉冲功率 (Ppp)：360 W @ 8/20 μs
- 反向电流 (Ir)：200 nA（nA 级超低泄漏）
- 结电容 (Cj)：1.5 pF
- 通道数：双路（两对线）
- 工作温度范围：-55 ℃ ~ +125 ℃
- 防护等级：符合 IEC 61000-4-5 及 IEC 61000-4-2（ESD ±30 kV 接触/空气）
三、主要特性
- 兼顾 ESD 与雷击脉冲防护：Ipp 30A、Ppp 360W（8/20 μs）能承受常见浪涌冲击。
- 超低工作电压与低钳位：Vrwm 3.3V、钳位电压低至 12V，适合 3.3V 系统。
- 极低泄漏电流：Ir 约 200 nA，减少对模拟/数字电路的干扰。
- 低结电容 1.5 pF：对 10/100/1000Base-T 等高速以太网信号影响小，利于信号完整性。
- 小尺寸封装 DFN2010-8，便于高密度布局与自动化贴装。
四、典型应用
- LAN/WAN 网络设备：交换机、路由器、网关、网络接口卡、光纤转换器等。
- 10/100/1000Base-T 以太网端口防护（两对线路保护适配多种 PHY 布局）。
- 其他需要低电容、低压浪涌保护的高速差分数据线接口。
五、封装与布局建议
- 将 LM-ULC332010T8 放置于 RJ45 或接口附近，尽量靠近可能受静电冲击的外部引脚，缩短导线感抗。
- 保护端到地的连线应尽可能短且宽，采用多颗地盲/通孔将底部散热焊盘与系统地相连以降低回路电感。
- 对于差分对信号，保持保护器件两侧走线对称，避免不必要的阻抗失配。
- 尽量在器件周围减少大块铜皮干扰，控制寄生电容以维护高速信号性能。
六、可靠性与合规性
LM-ULC332010T8 在设计上满足 IEC 61000-4-2（ESD）±30 kV（接触/空气）以及 IEC 61000-4-5（浪涌）要求，工作温度范围 -55 ℃ 至 +125 ℃，适合工业级和商业网络设备长期可靠运行。
七、典型连线说明
采用直通式保护结构时，通常将每对数据线的一端通过保护器件到地，或按器件数据手册建议的接法连接到 PHY/接口引脚。直通设计使得在 PCB 上无需复杂绕线，即可实现两对线的并列保护。
八、采购信息
品牌：Leiditech（雷卯电子）
型号：LM-ULC332010T8
封装：DFN2010-8
总结：LM-ULC332010T8 以其超低漏电、低结电容、低工作电压和高脉冲承受能力，适合对信号完整性要求高且需可靠防护的以太网及网络接口应用，能在有限空间内提供稳健的 ESD/浪涌保护解决方案。

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.
