SMD5542-3000 气体放电管产品概述

一、产品简介

SMD5542-3000 是 RUILON(瑞隆源)推出的表面贴装(SMD)气体放电管(GDT),封装尺寸 5.5 × 4.2 × 4.2 mm,双极结构(极数:2)。本器件在正常工作时表现为高绝缘电阻,等同开路,对电路无影响;当瞬态过电压超过放电阈值时,内部气体电离,器件迅速导通,将过电压钳制在安全水平,过后恢复高阻状态,保护并联电子设备或电路组件免受冲击损伤。

二、主要技术参数

  • 直流击穿电压 (Vdc):3 kV(±20%)
  • 冲击击穿电压 (Vimp):4.5 kV
  • 脉冲放电电流:3 kA
  • 极间电容:0.5 pF
  • 工作温度范围:-40 ℃ ~ +125 ℃
  • 外形尺寸:长 5.5 mm × 宽 4.2 mm × 高 4.2 mm
  • 封装形式:SMD,5.5×4.2mm
  • 品牌:RUILON(瑞隆源)

三、特性与优势

  • 高能量吸收能力:3 kA 脉冲放电电流承受能力,适合处理大能量浪涌事件。
  • 低极间电容:0.5 pF 的极间电容有利于高频电路中最小化信号畸变与干扰。
  • 宽温度范围:-40 ℃ 到 +125 ℃,适应苛刻工业与户外环境。
  • SMD 小封装:5.5×4.2mm 的表面贴装形式便于自动化贴装,节省 PCB 空间,利于紧凑型设计。
  • 快速响应与自恢复:瞬态出现即导通,过压消失后迅速恢复高阻态,重复使用寿命长。

四、典型应用场景

  • 通信设备防雷与浪涌保护(基站、光纤收发端口等)
  • 电力监测与继电保护系统的输入保护
  • 测试与测量设备的瞬态过压防护(高压表面贴装支持)
  • 工业控制、安防设备、汽车电子等需要高压浪涌抑制的场合

五、安装与使用注意事项

  • 建议靠近被保护元件或接口布置,以减小连线电感与抑制效果衰减。
  • 设计时考虑器件的极限值,避免在超出脉冲放电电流或功率的条件下工作。
  • 焊接工艺应符合 SMD 标准,避免长时间高温回流以保护密封性与性能稳定性。
  • 在高可靠性系统中,可与二极管、TVS 等器件联合使用,实现多级保护。

六、包装与采购

SMD 封装兼容自动化贴片生产线,RUILON 品牌保证出厂一致性与质量控制。购买时请确认型号 SMD5542-3000 及所需数量,必要时索取完整检验报告与可靠性数据。

如需更详细的电气曲线、冲击测试报告或 PCB 布局建议,可提供后续支持。

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
