SMD3216-090N 产品概述

一、产品简介

SMD3216-090N 是瑞隆源(RUILON)推出的一款小型表面贴装防护器件,封装尺寸为3.2×1.6×1.6 mm(SMD3216)。该器件为两极保护元件,直流击穿电压标称90V,允许峰值脉冲放电电流达500A,极间电容仅0.3 pF,适合对高能瞬态与高速信号同时要求的场合。工作温度范围为-40℃至+90℃,具备紧凑体积与高冲击承受能力(冲击击穿电压500V),适用于工业级、通讯及电源线路防护。

二、主要电气特性

  • 极数:2 极(双极/双端结构,便于串接在被保护线对上)
  • 直流击穿电压 (Vdc):90 V(±30%)
  • 脉冲放电电流:500 A(峰值,常用于8/20 µs冲击波形测试)
  • 极间电容:0.3 pF(低电容设计,对高速差分/单端信号影响极小)
  • 冲击击穿电压 (Vimp):500 V(器件对高能瞬态的耐受能力指标)
  • 工作温度:-40℃ ~ +90℃

注:±30% 精度通常指标称电压/击穿电压的容差范围,选型时请结合实际应用余量。

三、产品特点与优势

  • 小体积:3.2×1.6 mm 封装,便于高密度 PCB 布局与自动化贴片生产。
  • 高脉冲能力:500A 的峰值脉冲放电能力,可应对较大能量瞬态冲击。
  • 低寄生电容:0.3 pF,适合高速数据信号线路(如差分对、射频链路)的过压保护而不致明显降速或失真。
  • 宽工作温度:适用于室温及恶劣环境下长期运行。
  • 良好冲击耐受:500V 冲击耐受能力提高系统可靠性。

四、典型应用场景

  • 电源总线和中高压保护(如48V/72V工业母线防护)
  • 通信接口保护(以太网、串行差分线、高速信号通路)
  • 工业控制与传感器接口的瞬态抑制
  • 逆变器、太阳能/储能系统的局部防护器件
  • 任何要求低电容、紧凑封装且需承受高能瞬态的场合

五、安装与使用建议

  • PCB 布局:保护器件应尽量靠近被保护端口放置,走线短且宽以降低寄生电感;差分线保护时保持良好对称布局。
  • 焊接工艺:建议采用无铅回流焊,遵循 JEDEC/IPC 推荐回流曲线,峰值温度不超过 260℃。
  • 热管理:在高能脉冲频繁出现的环境,应考虑散热与周围器件耐受能力,必要时增加热铜/散热结构。
  • 选型余量:实际系统工作电压应显著低于器件直流击穿电压(Vdc),以避免频繁进入击穿并降低寿命。
  • 存储与搬运:避免静电及机械冲击,按常规电子元器件存储规范保存。

六、典型电路连接

  • 单端保护:器件两端并联在被保护线与地之间(或两端线间,视器件极性与系统接地而定)。
  • 差分对保护:直接跨接在差分对两线之间,以最低电容影响信号形态的方式布置。

七、选型与采购要点

  • 确认系统最大工作电压与预期瞬态能量,匹配器件的 Vdc、Ipp 与 Vimp。
  • 若用于敏感高速信号,优先考虑低极间电容规格(本件 0.3 pF 为低电容类产品)。
  • 关注批次一致性与供应商可靠性,向供应商索取详细数据手册与冲击试验条件。

SMD3216-090N 以其高脉冲承受能力、低寄生电容与紧凑封装,适合在要求高能抑制且对信号完整性敏感的应用中作为首选保护器件。如需完整电气特性曲线、典型击穿曲线与封装焊盘建议图,请联系瑞隆源或其授权代理获取详细数据手册。

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
