产品概述:DIOTEC 通用整流二极管 1A / 400V (SMA封装)

一、产品简介

本器件为 DIOTEC(德欧泰克)出品的通用整流二极管,采用 SMA(DO-214AC)封装,面向开关电源、适配器、家电驱动及通用整流场合。器件在 1A 工作电流下正向压降低(Vf=1.1V@1A),在高电压应用中具有良好的耐压与低漏泄特性。

二、主要电气参数

  • 正向压降(Vf):1.1V @ IF=1A
  • 直流反向耐压(Vr):400V
  • 额定整流电流(IF):1A(连续)
  • 反向电流(IR):≤5μA @ VR=400V
  • 非重复峰值浪涌电流(IFSM):30A(标准半波脉冲规格,典型 8.3ms)
  • 结温范围(Tj):-50℃ ~ +150℃

三、封装与热性能

SMA(DO-214AC)表面贴装封装,体积小、适合自动贴装与回流焊。该封装对热阻及散热路径有限,建议在设计时:

  • 在PCB上增加热铜箔与散热通孔,扩大散热面积;
  • 在高环境温度或高占空比条件下进行适当电流降额;
  • 遵循厂家回流焊温度曲线,避免超温影响器件可靠性。

四、适用场景

  • 开关电源次级整流与续流二极管;
  • 电源适配器、充电器整流;
  • 交流整流桥(单片或桥式使用);
  • 极性保护、反向保护与浪涌吸收场合;
  • 通用电子产品中的低至中功率整流需求。

五、使用要点与典型电路

  • 峰值浪涌电流(IFSM)表示短时冲击能力,非连续波形下安全余量有限,建议在存在高冲击条件时并联或选型更高Ifsm器件;
  • 反向漏流随温度上升增加,长期在高温高压下运行需考虑漏流带来的功耗与发热;
  • 典型连接:单个用于半波整流或作为桥式整流的单元,续流二极管并联负载以抑制感性回路的反向尖峰。

六、可靠性与储存

器件工作结温范围宽,适应严苛环境。存储与封装处理时应注意防潮、防静电;在长期储存后使用前建议回流前做烘烤以消除吸湿风险(遵循DIOTEC出厂湿气敏感等级说明)。

七、选型与替代参考

本型号适合对体积、自动装配与成本有要求的通用整流应用。若需更高耐压或更低正向压降,可参考同类器件或咨询厂商技术支持。常见替代器件示例:1N4004(同为1A/400V系列中的常见型号),但封装与热性能需按实际应用比对确认。

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
