2R3000T-8 气体放电管产品概述
一、产品概要
2R3000T-8（GDT-2P_8X8MM_TM）是RUILON（瑞隆源）出品的一款双极气体放电管（GDT），专为通信与电力等系统的高能脉冲浪涌防护设计。器件体积小巧（直径φ8mm、高度6mm），适合PCB面向面或点对点防雷与浪涌保护应用。
二、主要技术参数
- 极数：2极（双极/双端）
- 直流击穿电压 Vdc：3 kV（±20%）
- 冲击击穿电压 Vimp：4 kV
- 脉冲放电电流：5 kA（峰值）
- 极间电容：1.5 pF（典型）
- 工作温度范围：-40 ℃ ~ +125 ℃
- 外形尺寸：φ8 mm × 高6 mm
- 品牌：RUILON（瑞隆源）
注：直流击穿电压允许±20%公差，具体选型应参照实际工作电压与安全裕度。
三、产品特性与优点
- 耐高能量冲击：5 kA 脉冲放电能力，适用于雷击与强浪涌场景。
- 高击穿电压与良好耐压余量：3 kV Vdc（4 kV 冲击值），用于高电压回路时具有更佳的保护裕度。
- 低极间电容（1.5 pF）：对高速数据信号影响小，适合宽带、以太网、DSL 等敏感线路。
- 宽温度范围及紧凑外形：适合户外及工业环境的板级布置。
- 简单可靠：气体放电特性决定了吸收能量大、长期稳定性好，且在严重过压后可形成可控放电通道保护下游电路。
四、典型应用场景
- 电信基站、光纤收发端口、DSL/ADSL/FTTx 保护；
- 以太网/PoE 供电线路防雷保护；
- 工业控制总线（如 RS-485/RS-232）与信号接口；
- 电力配电与监测设备的浪涌防护模块；
- 户外设备和基站天馈线防护（配合适当接地）。
五、选型与安装建议
- 选型考虑工作电压与触发余量：工作电压应远低于直流击穿值，留有足够裕度以避免误触发。
- 与其他防护元件配合：常与TVS、熔断器或电阻并联或串联使用以兼顾响应速度与能量分担。
- PCB布局：保持放电管两端到敏感电路的最短路径并保证良好接地，遵循绝缘、爬电距离规范。
- 固定与焊接：器件属敏感机械结构，避免过热或过力，推荐按厂家工艺说明进行焊接与固定。
六、可靠性与维护
气体放电管在多次大能量放电后性能会逐步变化，建议在设计中预留检测或冗余。储存与运输避免强震动与剧烈温度变化，使用前检查外观与引脚状态。对长寿命或关键系统，应采用定期测试或更换策略以保证长期可靠性。
如需更详细的典型曲线（触发曲线、残压、冲击测试波形）或封装安装图，请提供用途场景与电路资料，以便给出更精确的选型与设计建议。

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.
