瑞隆源2R090TA-5瞬态抑制二极管产品概述

2R090TA-5是瑞隆源(RUILON) 推出的轴向引线瞬态抑制二极管(TVS),专为小功率电路的瞬态浪涌防护设计,核心优势在于「高脉冲耐受+低信号干扰+紧凑体积」的平衡,广泛适用于消费电子、通信、工业控制等领域的过压保护场景。

一、产品定位与核心价值

作为一款双向TVS管,2R090TA-5的核心价值是解决「浪涌防护与信号完整性」的矛盾:

  • 可快速响应并吸收电路中的瞬态浪涌(雷击感应、静电放电、电源开关尖峰);
  • 极低的极间电容不会干扰高频信号传输;
  • 小体积轴向封装适配PCB紧凑布局,双向设计无需区分极性,简化电路设计与安装。

二、关键性能参数解析

1. 击穿电压特性

  • 直流击穿电压(Vdc):标称90V,精度±20%,实际工作范围72V~108V;
    注:电路正常工作电压需≤60%Vdc(≤54V),避免器件误触发。
  • 冲击击穿电压(Vimp):500V(浪涌脉冲下的击穿电压),确保极端浪涌时快速导通。

2. 脉冲耐受能力

峰值脉冲放电电流(Ipp):5kA(8/20μs标准波形),可承受单次/多次中等强度浪涌(如户外设备雷击感应、电源开关尖峰),器件自身无损坏风险。

3. 信号兼容性

极间电容:仅1pF(远低于普通TVS的数pF~数十pF),在高频电路(2.4G/5G无线、高速数据接口)中,容抗对信号的衰减可忽略,避免信号失真。

4. 环境适应性

工作温度:-40℃~+90℃,覆盖工业低温(北方户外)与设备内部发热温度(路由器、机顶盒),满足多数场景需求。

三、封装与物理特性

采用轴向引线封装,尺寸为φ5.5mm(直径)×6mm(高度),属于小型化设计:

  • 适配常规PCB通孔焊接,无需特殊工具;
  • 封装材料为阻燃塑料(符合UL94 V-0等级),耐温性佳(焊接温度260℃/5s内无变形);
  • 轴向引线长度适配批量生产,安装便捷。

四、典型应用场景

1. 消费电子领域

  • 手机/平板/笔记本的充电接口(USB Type-C/A)浪涌防护,防止适配器异常或静电损坏充电电路;
  • 智能家电(电视、机顶盒)的信号端口(HDMI、AV)保护,避免雷击影响显示效果。

2. 通信设备领域

  • 路由器/交换机的以太网端口(RJ45)与射频端口(WiFi/蓝牙)防护,低电容确保无线信号无干扰;
  • 5kA脉冲电流抵御网络线路浪涌冲击。

3. 工业控制领域

  • PLC(可编程逻辑控制器)的输入输出端口、传感器接口(温度/压力传感器)防护,适应工业现场-20℃~+85℃环境。

4. 小功率电源电路

  • 适配器/开关电源的输出端浪涌抑制,防止负载短路或开关尖峰损坏后端电路。

五、应用注意事项

  1. 参数匹配:浪涌电流峰值需≤3.5kA(预留30%裕量),电路工作电压≤54V;
  2. 焊接工艺:焊接温度≤260℃,单次时间≤5秒,避免高温损伤;
  3. 布局设计:器件靠近防护端口(如充电接口),缩短引线长度,提升防护效果;
  4. 极性确认:双向TVS无需区分正负极,直接跨接线路与地即可。

2R090TA-5凭借高性价比、低干扰、紧凑体积等优势,是小功率电路浪涌防护的实用选择,尤其适合兼顾「防护性能与信号完整性」的场景。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
