SMD4532-090NB 产品概述

一、产品简介

SMD4532-090NB 是 BORN(伯恩半导体)推出的一款表面贴装气体放电管(GDT),采用 SMD 封装,外形尺寸 4.5 × 3.2 mm,器件高度 2.7 mm,双端(2端)结构。该器件专为防护通信接口、以太网、PoE 供电线路及其它需承受高能脉冲的电源/信号线路而设计,具备大能量浪涌吸收能力与极低对信号线的干扰(低极间电容),适合自动化贴片组装与紧凑电路板布局。

二、主要电气参数

  • 脉冲放电电流(Ipp):2 kA(单次浪涌能量能力,高电流吸收)
  • 直流击穿电压(Vdc):90 V(器件静态或缓慢升压时的触发电压基准)
  • 冲击击穿电压(Vimp):600 V(耐受短时脉冲或冲击情况下的参考电压)
  • 极间电容:0.8 pF(典型值,低电容适用于高速信号链路)
  • 极数:2 端(双端保护,常用于线对或线对-地)
  • 封装与尺寸:SMD,4.5 × 3.2 mm,长度 4.5 mm,宽度 3.2 mm,高度 2.7 mm
  • 精度/公差:±30%(器件触发电压或部分参数的工差范围,具体以数据手册为准)

三、产品特性与优势

  • 大脉冲承受能力:2 kA 的脉冲放电能力能有效吸收雷击、电源浪涌及其它瞬态高能事件。
  • 低寄生电容:0.8 pF 的极间电容对高速信号影响小,适合以太网、DSL、卫星/射频接口等敏感线路。
  • 紧凑 SMD 形态:4.5×3.2mm 的贴片封装支持表面贴装生产工艺,便于自动化装配与批量生产。
  • 可靠的两端保护:双端结构在信号线-线或线-地保护中更灵活,可按系统需求布局。
  • 品牌保障:BORN(伯恩半导体)制造与品质控制,适配工业与通信标准的防护设计。

四、典型应用场景

  • 宽带/以太网与 PoE 供电端口的过压冲击保护
  • 通信基站、光模块接口与数据线路防雷击、浪涌防护
  • 电源入口、逆变器与不间断电源的突发过压保护
  • 工业控制、楼宇自控与安防设备的高能瞬态防护

五、选型与设计建议

  • 考虑系统最大浪涌电流与能量:若系统可能遭受高于 2 kA 的极端冲击,应选择更高 Ipp 级别或与其它保护器件并联使用。
  • 对信号完整性敏感场合:低电容是优势,但仍建议与 TVS 二极管组合(TVS 负责快速钳位,GDT 负责高能量吸收)以获得更优保护。
  • PCB 布局:放电管引脚到参考接地应尽可能短且宽,减小串联电感;避开高阻回路以减少残留电压。
  • 温度与焊接:SMD 器件适用于常规回流工艺,具体回流曲线及存储、湿度敏感等级请参见原厂资料以保证可靠装配。

六、可靠性与维护

气体放电管属于低漏电、高能量吸收件;多次强冲击后可能需要检查或更换。建议对关键保护点进行浪涌事件后的功能验证。存储与使用期间避免超出器件额定电压和温度范围,以延长使用寿命和稳定性。

七、小结

SMD4532-090NB 是一款面向高能浪涌防护的紧凑型 SMD 气体放电管,凭借 2 kA 的脉冲放电能力、90 V 的直流触发电压与 0.8 pF 的低极间电容,适合在通讯、工业与电源系统中为敏感线路提供可靠的过压保护。设计时应结合系统浪涌水平、信号完整性需求及 PCB 布局,必要时与 TVS 等器件配合使用以实现最优的防护效果。如需精确的焊接温度曲线、寿命试验数据与典型波形响应,请参考 BORN 官方数据手册或联系供应商获取完整资料。

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
