SMD4532-090M 产品概述

一、产品简介

SMD4532-090M(品牌:DOWO/东沃)是一款面向中高压直流回路的表面贴装瞬态抑制器件,封装规格为1812(4.5mm × 3.2mm × 2.7mm)。器件设计用于吸收瞬时过压能量和浪涌脉冲,保护下游器件免受电压尖峰和冲击损害。工作温度范围为-40℃~+90℃,适合多数工业级和部分商用环境。

二、主要电气参数

  • 直流击穿电压(Vdc):90 V(标称)
  • 脉冲放电电流:2 kA(瞬态冲击能力,典型按8/20μs类波形评估)
  • 冲击击穿电压(Vimp):650 V
  • 极间电容:1 pF(低电容设计,适用于对寄生电容敏感的电路)
  • 精度:±20%(厂方标称公差)

三、结构与封装

  • 封装形式:1812 SMD(业界通用尺寸)
  • 外形尺寸:长度 4.5 mm,宽度 3.2 mm,高度 2.7 mm
    该尺寸利于自动贴装与回流焊工艺,便于在有限面积内实现高效的浪涌防护布局。

四、典型应用场景

  • 工业电源母线和直流配电(对中高压瞬态有保护需求的场合)
  • 逆变器与变换器的输入端浪涌防护
  • 通信基站、远程终端或监控设备的电源防雷/浪涌保护
  • 任何需要在受限空间提供高能量瞬态吸收且对电容敏感的线路保护场合

五、选型与使用建议

  • 未明确单向或双向型号标识时,选型前请向厂家核实以确定是否适用于直流或双向(交流)环境。
  • 在实际工程中,应结合系统可能出现的浪涌波形(如8/20μs)和能量水平校核器件是否满足长期可靠性要求。
  • PCB布线应尽量缩短接地与放电路径,使用多孔接地或大面积地平面以提升热耗散与冲击承受能力。
  • 建议配合熔断器、压敏电阻或其他二级防护措施以实现更高的系统可靠性。

六、包装、存储与可靠性

  • 适用于常见的SMD贴片生产线,包装方式通常为卷带/盘带,便于自动化贴装。
  • 存储与搬运应避免潮湿与强振动,建议遵循常规元件防潮回流焊前的烘烤与静电防护规范。
  • 温度范围-40℃到+90℃覆盖多数工业级应用,但在高温或恶劣环境下需评估老化与漂移影响。

七、注意事项与进一步资料

  • 本概述基于提供的关键参数编写,若需箝位电压曲线、能量吸收曲线或单向/双向确认,请索取东沃原厂完整数据手册。
  • 在关键应用(如车辆、轨道、航空等)使用前,应通过系统级认证与长期寿命验证。

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
