1N5822 产品概述

一、产品简介

1N5822 为肖特基(Schottky)整流二极管,由扬杰(YANGJIE)生产,封装为 DO-201AD 轴向引线式封装。此器件以低正向压降和快速恢复特性著称,适用于中等电流整流与开关电源的续流、整流、反向保护等场合。

二、主要参数

  • 正向压降 Vf:约 525 mV @ If = 3A
  • 最高反向耐压 Vr:40 V
  • 连续整流电流 If(AV):3 A
  • 反向漏电流 Ir:100 μA @ 40 V(随温度升高显著增加)
  • 工作结温范围:-55 ℃ ~ +125 ℃
  • 非重复峰值浪涌电流 Ifsm:80 A(典型按 8.3 ms 半正弦波测试)

三、产品特性与优点

  • 低正向压降:在较大直流电流下仍能保持约0.5V量级的压降,降低整流损耗与发热。
  • 快速响应、无反向恢复(肖特基特性):降低开关损耗与电磁干扰(EMI)。
  • 宽温度范围与良好浪涌承受能力:适合工业及汽车电子等苛刻环境。

四、典型应用

  • 开关电源(SMPS)输出整流;
  • DC-DC 降压/升压转换器中的续流二极管;
  • 反向电源保护与电源 OR-ing;
  • 太阳能、充电器、汽车电子等需要低压降整流的场合。

五、使用与设计注意事项

  • 热管理:标称 3A 连续整流通常需要短引线或良好散热措施,轴向 DO-201AD 依靠引线与外部散热体散热,环境温度升高时应按热阻与结温限制进行电流降额。
  • 漏电流随温度增加:在高温或高反向电压下漏电流上升,应评估待机或断电条件下的功耗。
  • 浪涌能力:80A 为非重复峰值浪涌(常以 8.3 ms 半正弦波标准),用于短时突发过流,但不能作为长期超载依据。
  • 焊接与安装:DO-201AD 为轴向贯穿件,推荐规范焊接工艺,避免过高温度或过长加热时间以保护器件结构与可靠性。

六、封装与可靠性

DO-201AD 轴向封装便于手工或波峰/选择性焊接,机械强度较高,适合需要较大电流和良好机械支撑的应用。工作结温范围宽,适合工业等级设计,但在高功率方案中仍需外部散热设计。

七、选型建议

若系统要求低压降、高效率且工作电流在 3A 附近,1N5822(YANGJIE,DO-201AD)为经济且实用的选择;若需更高反向耐压或更低漏电流/更高频率特性,可考虑更高规格的肖特基或同步整流方案。选型时应结合最大结温、环境温度、散热条件及允许的漏电流进行综合评估。

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
