3R090TB-8 产品概述
一、概述
3R090TB-8 是瑞隆源（RUILON）推出的一款三端（3极）气体放电管（GDT）保护器件，采用插件封装，外形尺寸 φ8mm × 10mm。器件针对中低电压电路的浪涌与雷击脉冲提供快速放电通道，兼顾低电容特性，适合对信号完整性要求较高的保护场合。
二、主要性能与参数
- 直流击穿电压（Vdc）：90V，精度 ±20%（实际工作范围约 72V–108V）
- 冲击击穿电压（Vimp）：600V
- 脉冲放电电流：10kA（器件抗浪涌能力）
- 极间电容：1.5pF（低电容，利于高速信号传输）
- 极数：3（常用于双线对地保护，如 Tip/Ring/Ground）
- 工作温度：-40 ℃ ～ +90 ℃
- 尺寸：直径 φ8mm，长度 10mm
- 封装：插件（Through-Hole）
三、工作原理与典型应用
3R090TB-8 在正常工作时呈高阻状态，对线路影响极小；当外加过电压或浪涌达到其击穿电压时，气体放电形成低阻通道，将瞬态能量导入地线或旁路回路，从而保护后端设备。三极设计便于同时实现两线（差分）与地之间的保护，典型应用包括：
- 通信线路与电话接口防雷（Tip/Ring/Ground）
- 以太网端口、DSL、光纤收发器的浪涌保护前端
- 工业控制与测量设备的瞬态过电压防护
四、安装与使用注意事项
- 推荐插件焊接工艺，避免过度加热；安装时保证引脚牢固且接地可靠。
- 低电容特性有利于高速信号，但在高频或射频场合仍需评估对链路影响。
- 工作环境保持在额定温度范围内，并注意器件在多次大电流冲击后的性能退化，必要时予以更换。
- 三端接法需确保接地回路低阻抗，以便浪涌能量能迅速泄放。
五、选型建议
- 若保护电路为直流或低压供电线路，请选择直流击穿电压高于正常工作电压但低于系统可承受的过电压。
- 对高频信号链路，优先考虑低极间电容（本型号 1.5pF）以降低信号失真。
- 根据可能遭受的浪涌强度选择合适的脉冲放电电流额定值，本型号 10kA 适用于多数雷击/开关冲击场景。
六、产品优势小结
3R090TB-8 以紧凑的插件外形、三端差分保护能力、90V DC 阈值与 10kA 抗浪涌能力为特色，辅以仅 1.5pF 的极间电容，兼顾防护性能与信号完整性，适合通信、电源与工业控制等多种需要瞬态过电压保护的应用场景。如需详细器件曲线、浪涌波形测试条件或样品支持，请联系瑞隆源技术与销售渠道。

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.
