3RL075M-5-S 产品概述
一、产品简介
3RL075M-5-S 是 KUU 品牌的一款三极瞬态过压保护器件，适用于中继器、调制解调器等通讯设备的线路防护。器件设计以稳定击穿电压与低互电容为核心，专为保护信号线免受雷电脉冲和开关脉冲影响而优化。
二、主要技术参数
- 极数：3
- 直流击穿电压 (Vdc)：75 V（±20%）
- 冲击击穿电压 (Vimp)：600 V
- 脉冲放电电流：5 kA（峰值）
- 极间电容：≤ 1.5 pF
- 工作温度：-40 ℃ ～ +90 ℃
- 尺寸：直径 φD = 5 mm，长度 = 7.2 mm，宽度/高度 = 5 mm
- 封装：5x7.2
- 品牌：KUU
三、性能特点
- 稳定的击穿电压：75 V 名义值，±20% 精度，确保在设计范围内触发保护。
- 大吸收瞬态电流能力：可承受单次脉冲峰值 5 kA，适合雷电和大能量瞬态场景。
- 低极间电容：≤1.5 pF，极小的寄生电容对高速/宽带信号影响极小，适合敏感通信线路。
- 高绝缘电阻与高额定电流：静态漏流低，长期在线不会影响信号完整性。
- 容易集成：尺寸紧凑、封装规范，便于印制板安装与批量装配。
四、典型应用
- 电话线、宽带调制解调器（ADSL/DSL）和中继器线路保护
- 通信设备输入端的浪涌保护与地线保护
- 需要低通带损耗和高能量吸收的信号链路防护场景
五、安装与使用建议
- 建议将器件并联接入被保护线路：两条信号线分别对地或线间接入，以实现三极（线—线—地）保护。
- 为防止跟随电流和延迟触发，常与固态限幅器（如TVS）配合使用：GDT（本器件）吸收高能量脉冲，TVS 提供快速限幅。
- 在高能量环境下配合熔断器或限流元件使用，以避免设备在多次大脉冲后失效导致的后果。
- 安装时避免机械应力，焊接温度与时间应符合工艺规范，保持器件引脚清洁并保证良好接地。
六、存储与可靠性
- 存储温度与工作环境避免长期湿度、腐蚀性气体和强振动；按通信设备常规可靠性要求进行环境试验。
- 在额定条件下，器件具有长期稳定性；实际寿命受冲击次数与能量大小影响，建议设计裕度并做必要的过载保护。
七、包装与型号说明
- 型号：3RL075M-5-S（KUU）
- 封装规格：5x7.2（直径 5 mm，长度 7.2 mm）
- 若需样品、批量报价或详细应用资料（典型电路图、耐久性测试报告），请提供使用场景与预期脉冲条件，以便进一步技术支持。

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.
