LESD8D3.3CAT5G 产品概述
一、产品简介
LESD8D3.3CAT5G 是富芯森美（FUXINSEMI）出品的一款单路双向ESD/浪涌保护二极管，针对3.3V系统及高速信号线的瞬态过压防护而设计。器件响应快、泄漏小、承受能力强，适配需要低电容的通信接口保护需求。
二、主要参数
- 极性：双向
- 反向截止电压 (Vrwm)：3.3V
- 击穿电压：3.7V（典型）
- 钳位电压：10V（在峰值脉冲电流下）
- 峰值脉冲电流 (Ipp)：10A
- 峰值脉冲功率 (Ppp)：100W
- 反向电流 (Ir)：100nA（典型，常温）
- 结电容 (Cj)：15pF
- 通道数：单路
- 工作温度：-55℃ ~ +125℃
- 防护等级：符合 IEC 61000-4-5 与 IEC 61000-4-2 标准
- 封装：SOD-882
三、关键特性
- 低结电容（15pF），对高速数据传输影响小，适合网口、USB、串行高速差分信号保护。
- 双向设计，可同时抑制正负瞬态脉冲，适用于差分线与双向供电场景。
- 高能量吸收能力（100W,Ppp）和10A峰值脉冲电流，增强对雷击和开关浪涌的抵抗力。
- 极低泄漏电流（100nA）保证对敏感电路的干扰最小化。
四、典型应用
- 以太网（尤其高速链路、CAT5/5e/6前端保护）
- USB、HDMI 等接口的ESD与浪涌防护
- 工业控制通讯接口、I/O 端口保护
- 汽车电子的低压信号线保护（需按车规验证）
五、封装与可靠性
SOD-882 小型封装便于表面贴装和自动化生产，适合空间受限的终端设备。器件工作温度范围宽，满足工业级环境要求，且已通过 IEC 静电放电与浪涌抗扰度测试指标。
六、设计与使用建议
- 将 LESD8D3.3CAT5G 靠近受保护引脚布置，最短走线以降低寄生电感。
- 对差分对建议对称放置单通道或配对使用以确保一致性。
- 在高频或极低噪声系统中，评估15pF 电容对信号完整性的影响，必要时采用并联或串联滤波配合。

Request for quote
Send RFQ
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.
