1N5824 产品概述

一、产品简介

1N5824 为 DOWO(东沃)出品的一款功率肖特基整流二极管,采用 DO-201AD 轴向封装,适用于中等功率整流和保护电路。该器件以低正向压降和优良的浪涌承受能力见长,适配工业级温度要求,适合要求高可靠性的电源模块和功率控制应用。

二、主要参数

  • 工作结温范围:-65℃ ~ +150℃
  • 直流整流电流(Io):5A
  • 正向压降(Vf):0.55V @ 5A
  • 非重复峰值浪涌电流(Ifsm):150A(单次冲击)
  • 直流反向耐压(Vr):30V
  • 反向电流(Ir):500μA @ 30V
  • 封装:DO-201AD(轴向)

三、性能与优势

1N5824 的正向压降约 0.55V(5A 条件),相较传统硅整流器能显著降低整流损耗与发热,提升转换效率。150A 的峰值浪涌能力保证了器件在启动、短路或电容充电时的抗冲击能力。宽温区间(-65℃~150℃)使其可用于汽车电子、通信设备及工业电源等恶劣环境中。DO-201AD 轴向封装可靠、便于穿孔安装并具有良好机械强度。

四、典型应用场景

  • 开关电源输入整流与续流二极管
  • DC-DC 转换模块的输出整流
  • 电机驱动和继电器驱动的反向保护与续流
  • 电源反接保护、电池充放电路径
  • 高脉冲冲击场合的瞬态电流承受

五、选型与使用建议

选择时除参考 Vr、Io、Ifsm、Vf、Ir 等关键参数外,应关注实际工作环境的结温与散热条件。建议在高电流持续工作时做适当电流降额与强制散热处理;长时间处于高温或高反向电压时反向漏电随温度上升显著增加,应核对电路容忍度。若需替代型号,务必保证封装、电流、电压及浪涌能力相当,并优先参考原厂 datasheet。

六、封装与焊接注意

DO-201AD 为轴向引线封装,常用于穿孔焊接。焊接时避免长时间高温加热以防封装或内部结构受损;引线弯折应在离封装一定距离处进行,避免对端帽或内部接合点施加机械应力。储存与焊接操作遵循常规电子元件防潮、防冲击及防静电规程。

综上,1N5824 是一款适用于中功率、高冲击、宽温工作环境的肖特基整流器,凭借低正向压降与良好的浪涌承受能力,在电源与保护电路中具备良好实用性。具体电路设计与热设计细节建议参照生产厂家的完整规格书与应用说明。

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
