3RL090M-5-S 产品概述
一、产品亮点
3RL090M-5-S 是 KUU 推出的 SMD 封装浪涌保护器件，针对需要高冲击能量抑制且对信号完整性要求高的应用场景设计。主要亮点包括：三极（极数：3）结构、直流击穿电压约 90V（±20%），单次脉冲放电能力高达 5kA，极间电容仅 1.5pF，适合在有限空间内实现高能量吸收且对高速信号影响极小。
二、技术规格概述
- 极数：3
- 直流击穿电压 (Vdc)：90V（±20%）
- 脉冲放电电流：5kA（峰值，适用于短时大电流冲击）
- 极间电容：1.5pF（低电容，有利于高速信号通道）
- 冲击击穿电压 (Vimp)：600V（瞬态冲击响应能力）
- 工作温度范围：-40℃ ~ +90℃
- 尺寸：直径 φ5mm，SMD 封装
- 品牌：KUU
- 精度：±20%
三、典型应用场景
- 通信接口保护：适用于以太网、DSL、光纤收发器附近的防雷/浪涌保护，低电容特性有利于保持数据链路的带宽和信号完整性。
- 电力与POE接口：对直流工作电压不超过额定值（约90V）的供电线进行过电压防护。
- 工业控制与自动化：用于现场总线、传感器接口与弱电控制回路的浪涌能量吸收。
- 电源输入端与配电保护：配合其他保护器件（如TVS）形成多级保护，提升系统整体抗雷击、抗浪涌能力。
四、结构与工作原理简述
该器件为气体放电类或开关型浪涌抑制元件（依据具体型号与制造工艺），在正常工作条件下维持高阻态，不影响信号传输；当外部瞬态电压超过其击穿门槛时，器件迅速导通，将大部分冲击能量导入地线或吸收，从而保护下游电路不受损害。较高的脉冲放电电流（5kA）与600V 的冲击击穿能力，使其能处理常见雷电及开关瞬态事件。
五、封装与安装建议
- SMD 封装、直径 φ5mm，适合表面贴装工艺和高密度 PCB 布局。建议靠近被保护接口（如连接器、变压器次级）布置，以缩短两端路径，减小感应电压。
- 焊接与回流工艺请参照 KUU 官方焊接规范，避免过高温度或长时间保温导致内部结构损伤。
- 存储与使用环境应避免潮湿、腐蚀性气体与强机械应力，工作温度范围为 -40℃ ~ +90℃。
六、选型与使用建议
- 若被保护线路的正常工作电压接近或高于直流击穿电压，应选用更高耐压型号或采用多级保护方案。
- 对于高速差分信号（如千兆以太网），低电容（1.5pF）是重要优势，但仍需与 PCB 匹配阻抗、接地布局一并考虑。
- 建议与 TVS 二极管、共模扼流圈等配合使用，实现快速钳位与大能量吸收的互补保护。
- 采购与设计前请索取并确认厂家完整数据手册和可靠性试验报告，以验证器件在目标应用下的长期稳定性。

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.
