RL102-141N 瞬态抑制二极管产品概述

一、产品定位与核心功能

RL102-141N是RUILON(瑞隆源) 推出的轴向引线式瞬态抑制二极管(TVS),专为低压电子设备的过压浪涌防护设计,核心作用是快速吸收瞬间过压冲击(如雷击、开关浪涌、静电放电),保护后端敏感元器件(IC、电容、LED等)免受损坏。该器件属于通用型防护器件,适配电压等级覆盖100V以下电路,满足日常电子设备的基础防护需求。

二、关键技术参数与性能优势

结合器件核心参数,其性能特点可总结为“小型化、宽温适应、低电容、高浪涌承受”:

1. 击穿电压与精度

标称击穿电压140V±30%(实际范围约98V~182V),既避免因精度偏差导致防护失效,又适配不同电压等级的电路(如工作电压100V的电源模块可直接匹配)。

2. 绝缘与电容特性

  • 绝缘电阻≥100MΩ:正常工作状态下与电路保持良好绝缘,防止漏电影响稳定性;
  • 电容仅1pF:远低于普通压敏电阻,可应用于高频信号线路(如RS485接口、USB低功率端),不衰减信号传输。

3. 浪涌与环境适应性

  • 最大浪涌电流1kA(8/20μs波形):快速响应并吸收瞬间能量,满足IEC 61000-4-5浪涌抗扰度标准;
  • 工作温度**-45℃~+85℃**:覆盖低温(北方户外)和高温(设备内部散热区),环境适应性强。

4. 封装尺寸

轴向引线封装,直径φ2.6mm:体积小巧,节省PCB空间,适合便携式设备、小型家电的紧凑布局。

三、封装与安装特性

采用轴向引线封装,引脚长度适中,支持手工焊接或机器插件;φ2.6mm的小型化设计可适配高密度PCB布局,安装时需注意:

  • 引脚间距需符合设计要求,避免短路;
  • 焊接温度≤260℃,焊接时间≤3秒,防止高温损坏器件;
  • 双向导通特性(无正负极区分),简化安装流程。

四、典型应用领域

该器件的防护特性适配多场景需求,核心应用包括:

1. 小家电防护

电磁炉、电饭煲、电热水壶等电源输入端,吸收开关浪涌或雷击过压;

2. 低压电源模块

LED驱动电源、小型开关电源的输出端,保护后端LED灯珠或控制IC;

3. 信号接口防护

RS485通信接口、USB低功率端口等信号线路,利用低电容避免信号干扰;

4. 工业小型设备

小型传感器、执行器的电源/信号端,适应宽温环境下的浪涌防护。

五、可靠性与选型注意事项

1. 可靠性表现

  • 符合常见防护标准(IEC 61000-4-5、GB/T 17626.5);
  • 高绝缘电阻确保潮湿环境下性能稳定;
  • 浪涌能力经过实际测试,可应对日常过压冲击。

2. 选型与使用注意

  • 击穿电压需为电路工作电压的1.2~1.5倍(如100V电路选140V器件);
  • 若浪涌需求超过1kA,可并联同型号器件(需保证击穿电压一致性);
  • 避免长期暴露在高湿度(>90%RH)或腐蚀性气体环境,必要时灌封防护。

六、总结

RL102-141N凭借小型化、宽温、低电容、高性价比等优势,成为低压电子设备过压防护的优选器件,适用于家电、电源、通信接口等多场景,能有效提升设备抗干扰能力与可靠性。

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
