2R800TB-8 气体放电管（GDT）产品概述
一、产品基本定位
2R800TB-8是RUILON（瑞隆源）推出的二极式气体放电管，属于电子设备过电压保护核心器件，主要用于抑制电路中的瞬态浪涌（如雷击、开关干扰、静电放电），避免敏感元器件（芯片、传感器等）因过压损坏。其设计兼顾小体积与高防护性能，适配紧凑化电子设备的集成需求。
二、核心电气性能参数
该型号GDT的关键参数直接决定防护能力，具体特性及实际意义如下：
- 直流击穿电压（Vdc）：标称800V，精度±20%（实际范围640V~960V）。
电路正常工作时，器件处于高阻态（漏电流极小），不影响信号/电源传输；当瞬态过电压超过击穿阈值时，快速导通泄放能量。 - 脉冲放电电流：最大耐受10kA（8/20μs标准浪涌波形）。
可应对强瞬态干扰（如近距离雷击），有效泄放浪涌能量，保护后端电路。 - 极间电容：仅1pF（低电容设计）。
对高频信号（通信、射频电路）传输损耗极小，不影响信号完整性，适合敏感高频设备防护。 - 冲击击穿电压（Vimp）：1.3kV。
反映脉冲电压下的击穿特性，与直流击穿电压配合，覆盖不同过压场景（如慢上升浪涌、快脉冲干扰）。
三、机械与环境适应性
- 机械尺寸：直径φ8mm，高度6mm（小型化封装）。
可轻松集成到PCB板紧凑布局中，适配空间受限设备（如小型通信模块、电源适配器）。 - 工作温度范围：-40℃~+90℃（宽温设计）。
可在户外、工业环境等极端温度场景下稳定工作，满足多样化应用需求。 - 封装类型：陶瓷封装。
具备良好绝缘性、耐腐蚀性，长期使用可靠性高，不易受环境因素（湿度、灰尘）影响。
四、典型应用领域
基于其性能特点，2R800TB-8适用于以下场景：
- 通信设备：ADSL、光纤收发器、路由器等数据端口防护，应对雷电浪涌与静电干扰。
- 电源系统：开关电源、UPS输入/输出端过压保护，防止浪涌损坏功率器件。
- 工业控制：PLC、传感器等工业电子设备防护，适配工业环境的宽温与干扰需求。
- 车载电子：部分高防护要求的车载设备（如车载通信模块）辅助防护（需配合TVS等器件使用）。
五、使用注意事项
- 安装方式：需并联在被保护电路的相线与地之间（或信号端与地之间），确保瞬态能量快速泄放。
- 并联扩容：若需更高防护电流，可采用多只器件并联（注意参数一致性），禁止串联（串联会提高击穿电压，影响防护效果）。
- 温度限制：需在-40℃~+90℃范围内使用，超出范围可能导致参数漂移或性能下降。
- 布局要求：安装时与其他器件保持合理间距（避免热累积），焊接温度需符合陶瓷封装耐受标准（一般≤260℃）。
六、总结
2R800TB-8作为一款高性价比的二极式GDT，以小体积、低电容、高浪涌耐受为核心优势，可广泛应用于通信、电源、工业等领域的过电压防护，是电子设备抗干扰设计的常用可靠选择。

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.
