3R230A-5S 产品概述

一、产品简介

3R230A-5S 是 RUILON(瑞隆源)推出的一款表面贴装(SMD)过电压防护器件,采用三极结构设计,专为对高能脉冲和雷击浪涌进行钳位和放电保护而优化。器件体积小(7.5×5×5mm),寄生电容低(≈1pF),适合用于对信号完整性和高频特性有要求的保护场合。

二、主要性能特点

  • 三极结构,适用于三线/三相或多回路联合防护设计。
  • 直流击穿电压 Vdc:230 V(典型),在此电压附近开始导通放电。
  • 冲击击穿电压 Vimp:700 V(典型),在高冲击条件下保持可靠放电能力。
  • 脉冲放电电流 Ipp:5 kA(峰值),可承受较强雷电脉冲和开关过电压。
  • 极间电容约 1 pF,适合高速信号线路的保护,减小对信号的影响。
  • 工作温度范围广:-40 ℃ ~ +90 ℃,适应工业级环境。
  • 小型 SMD 封装(7.5×5 mm),便于自动贴装与批量生产。

三、技术参数(概览)

  • 型号:3R230A-5S
  • 品牌:RUILON(瑞隆源)
  • 极数:3 极
  • 直流击穿电压(Vdc):230 V ±20%
  • 冲击击穿电压(Vimp):700 V
  • 脉冲放电电流(Ipp):5 kA(标准脉冲测试条件下)
  • 极间电容:≈1 pF
  • 环境温度:-40 ℃ ~ +90 ℃
  • 外形尺寸:7.5 mm × 5 mm × 5 mm;直径 φD:5 mm;封装形式:SMD

四、封装与机械特性

  • SMD 贴装封装,适配自动贴片和回流焊工艺(请在工艺参数上与供应商确认回流曲线)。
  • 体积小巧,占板面积小,便于在受限空间内实现局部保护布局。
  • 低电容特性有利于高速数据线、通信接口及测量线路的并联保护。

五、典型应用场景

  • 通信设备:基站、交换机、数据传输端口的浪涌保护。
  • 电力与配电:低压配电系统的三相浪涌防护与保护模块。
  • 工业控制:PLC、传感器接口和现场总线(如485/422)等容易受脉冲干扰的线路。
  • 安防与监控:摄像头、电源线和信号线的防雷击和过电压保护。

六、使用建议与注意事项

  • 常与金属氧化物压敏电阻(MOV)、瞬态电压抑制二极管(TVS)等器件配合,构成多级浪涌保护,提高系统可靠性。
  • 布局时尽量缩短保护器件与被保护端之间的走线,减小回路电感,提高放电效率。
  • 对于高频信号线,注意器件极间电容对信号带宽的影响,必要时在设计评估中进行测试验证。
  • 在焊接、清洗及回流工艺前,与制造商确认工艺兼容性与最大工艺温度,以避免器件损伤。
  • 对关键应用建议做样品评估,包括击穿电压、漏电流、脉冲承受能力和重复击穿后的可靠性测试。

七、储存与可靠性提示

  • 储存环境建议干燥、无腐蚀性气体、温度与湿度适中,避免长期高温或潮湿环境。
  • 出货或铺板前建议进行来料检验(外观、标称电气参数抽测),关键项目可保留批次追溯记录。
  • 如需高可靠性应用(例如电力站、重要通信枢纽),建议与供应商沟通定制化测试或更高等级的寿命验证计划。

总结:3R230A-5S 以其三极设计、5kA 脉冲承受能力、低电容与小型 SMD 封装,适合在对抗强脉冲及要求信号完整性的系统中担任关键的浪涌与过电压保护元件。选型与设计时应结合具体应用环境与防护策略,合理搭配其他防护元件以达到最佳保护效果。

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
