Brightking 3RL150M-5-S 放电管（SMD-3P）产品概述
一、产品简介
3RL150M-5-S 是台湾君耀（Brightking）出品的一款三极（3P）表面贴装放电管，专为电路过电压和雷击脉冲保护设计。器件体积小巧（直径φ5mm，长度7.2mm），适用于需高能量吸收与低附加电容的保护场合。
二、主要性能特点
- 极数：3 极，适用于三线或两线加地的保护拓扑。
- 直流击穿电压（Vdc）：150V，允许±20%公差，满足常见工频及直流过压门槛要求。
- 冲击击穿电压（Vimp）：600V，指示器件对瞬态高电压的耐受能力。
- 脉冲放电电流：5kA（峰值），能够承受较大能量的雷电或开关瞬变冲击。
- 极间电容：2pF，极低的电容对高速信号线影响小，适合对信号完整性要求高的线路。
- 工作温度范围：-40℃ ~ +85℃，适用于工业级环境。
三、典型应用场景
- 通信设备（电话线、防雷模块）与DSL线路防护；
- 网络终端、基站与交换设备的输入保护；
- 工业控制系统、电力监控与仪表的浪涌保护；
- 消费电子的电源端子与接口保护场合，尤其在要求低串扰的高速信号线路中优势明显。
四、封装与安装建议
- 封装形式为 SMD-3P，兼容自动贴装与回流焊流程；器件小尺寸有利于电路板密集布局。
- 安装时应保证焊盘与铜箔散热/绝缘合理布局，避免过近的强电势导体；
- 推荐遵循实际生产线回流焊曲线，避免长时间超温；贴装位置应便于接地平面和引流路径设计以优化放电路径。
五、注意事项与选型建议
- 直流击穿电压有±20%公差，选型时应根据系统工作电压和安全裕度预留足够余量；
- 器件为气体放电型保护元件，触发时会产生瞬态放电，后续可能需要与限流或熔断元件配合；
- 如需更高能量或更低触发电压的方案，可与金属氧化物压敏电阻（MOV）、瞬态抑制二极管（TVS）等组合使用；
- 在关键系统应做完整的浪涌试验验证，包括符合行业标准的脉冲与耐压测试。
六、包装与环境适应性
- 适用于工业环境工作温度范围（-40℃ ~ +85℃）；存储与使用时应避免潮湿、强腐蚀性气体环境。
- 出货通常为适合SMT流程的卷带或盘装，便于自动化生产线使用。
总结：3RL150M-5-S 以其小体积、低极间电容（2pF）与较高脉冲放电能力（5kA）在通信、网络与工业保护领域具有良好应用价值。选型时请结合系统工作电压、浪涌能量及安装工艺进行综合评估，并在最终设计中完成必要的电气与环境测试验证。

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.
