2R2000T-8 产品概述
2R2000T-8 是瑞隆源（RUILON）推出的一款高压气体放电管（GDT），专为雷击、开关过电压和快速上升瞬变的浪涌防护设计。器件以两极直插封装形式提供，具有高击穿电压、低极间电容和良好的冲击承受能力，适用于通信、天馈、工业电源及高隔离偏置线路的浪涌保护场景。
一、主要性能特点
- 击穿电压（Vdc）：2.0 kV（典型），公差 ±20%
- 冲击击穿电压（Vimp）：2.8 kV（典型）
- 脉冲放电电流：5 kA（8/20 μs），联合或特殊测试可达 10 kA 级别
- 极间电容：≈1.5 pF（低电容，适合高速/射频信号路径）
- 极数：2（双极电极结构）
- 工作温度：-40 ℃ 至 +125 ℃
- 外形尺寸：直径 φ8 mm，厚度/高度 6 mm
- 封装形式：插件（直插式），便于现场更换与维修
二、产品优势
- 高耐冲击能量：在标准 8/20 μs 测试下具备大电流放电能力，能有效截断雷电及大幅度瞬变。
- 低电容影响：1.5 pF 的极间电容对信号链影响小，适合用于敏感信号及高频应用。
- 宽温度范围与高可靠性：-40~+125 ℃ 的工作温度，满足严苛工业及户外环境要求。
- 与MOV/TVS协同使用效果更佳：可与压敏电阻配合，为交流和混合频段系统提供分级保护。
三、典型应用场景
- 电信/基站天馈保护、天线馈线防雷
- 直流偏置/高压隔离电路的浪涌保护（如光收发模块、偏置电源）
- 配电箱与工业控制系统的输入浪涌抑制
- 与MOV/TVS组合的交流侧分级防护
四、使用建议与注意事项
- 接地与布局：将放电管至地的接地线尽可能短且阻抗低，PCB 上放电管附近走线应简洁，避免长走线引入寄生感抗。
- 组合防护：对连续能量或后级设备敏感的系统，建议与 MOV/TVS 并联使用，GDT 负责高能瞬变首要击穿，MOV/TVS 负责钳位余压。
- 不作为连续导通器件：气体放电管在放电后可能出现后续电流（跟踪电流），需确保电路有限制或切断机制以防器件持续导通。
- 环境与储存：避免在高湿或腐蚀性气体环境长期暴露，储存期间应防潮、防静电。
五、检测与安装提示
- 选型确认击穿电压与系统工作电压间留有足够裕量（典型 2 kV Vdc，偏置电压应小于此值）。
- 安装时避免机械冲击或强振动，插件结构建议在波峰或手工焊接时采取合适的温度曲线以保护内部结构。
- 建议在样机阶段进行 8/20 μs 浪涌测试与重复冲击寿命试验，验证系统整体防护性能。
2R2000T-8 以其高压等级、低电容与强耐冲击能力，是需要对高电压瞬变、雷击干扰进行可靠防护系统的理想选择。若需更详细的电气曲线、冲击测试报告或定制化封装支持，可联系瑞隆源技术团队获取进一步资料。

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.
