1N4007通用整流二极管产品概述

1N4007是一款经典的硅基通用整流二极管,由钜兴(JUXING)电子生产,采用DO-41轴向封装,广泛应用于消费电子、工业控制、家用电器等领域的基础整流场景。凭借稳定的电气性能、宽温适应能力与可靠的封装设计,成为中低压整流电路的常用核心器件。

一、产品定位与基本属性

本款1N4007属于标准整流二极管系列,核心功能为实现交流电到直流电的单向转换,或电路中的单向导通保护。产品符合国际通用电气参数规范,可兼容同规格其他品牌器件,适配多数常规电子电路的设计需求,是小功率至中等功率整流场景的高性价比选型。

二、核心电气参数详解

产品关键参数直接决定应用范围,具体如下:

  1. 正向压降(Vf):1.1V@2A
    正向导通时,2A电流下的压降为1.1V,属于硅二极管典型特性(电流增大时压降略有上升),1A电流下压降约0.9V,功耗控制符合行业标准。
  2. 直流反向耐压(Vr):1kV
    额定反向耐压1000V,可覆盖220V/380V交流系统的整流需求(如220V交流峰值约310V,余量充足),避免反向击穿风险。
  3. 直流整流电流(IF):1A
    正向平均电流额定值1A,适用于5W-50W左右的小功率电源(如手机充电器、小型稳压电源),大电流场景需并联或选型更高规格器件。
  4. 反向漏电流(Ir):5uA
    反向耐压下漏电流仅5μA,远低于行业常规≤10μA的标准,可有效减少反向功耗,提升电路效率与可靠性。
  5. 非重复峰值浪涌电流(Ifsm):30A
    单次浪涌电流能力达30A,可抵御开机瞬间、负载突变等冲击电流,避免器件损坏。
  6. 工作结温范围:-55℃~+125℃
    宽温覆盖工业级与消费级环境,可在极端低温(如户外设备)或高温(如电源内部)场景下稳定运行。

三、封装与物理特性

本产品采用DO-41轴向封装,具体特性:

  • 封装形式:轴向引线(两端带焊脚),便于PCB焊接或导线连接;
  • 工艺设计:玻璃钝化工艺,提升抗潮湿、抗机械应力能力,延长使用寿命;
  • 尺寸规格:常规DO-41封装(直径约2.7mm,长度约5.2mm),适配标准PCB焊盘,无需特殊布局。

四、典型应用场景

  1. 电源适配器整流:手机充电器、笔记本电源、小型家电(台灯、加湿器)的交流转直流环节;
  2. 线性电源整流桥:小型稳压电源(5V/1A、12V/0.5A)的整流桥堆组成(4个1N4007组合);
  3. 开关电源辅助电路:开关电源辅助绕组整流、待机电源整流;
  4. 家用电器控制:微波炉、洗衣机、空调等设备的小功率控制电路整流;
  5. 工业控制电路:PLC、传感器模块的辅助电源整流,或低电压信号的单向导通保护。

五、性能优势分析

  1. 耐压余量充足:1kV反向耐压覆盖多数民用与工业低压系统,无需额外降压设计;
  2. 低功耗设计:5μA反向漏电流与合理正向压降,降低电路总功耗,减少散热需求;
  3. 高可靠性:DO-41封装的玻璃钝化工艺,结合宽温范围,适应复杂环境;
  4. 抗冲击能力强:30A浪涌电流抵御突发电流冲击,提升电路稳定性;
  5. 成本效益高:经典通用器件,量产成熟,价格亲民,适合批量应用。

六、使用注意事项

  1. 电流限制:实际正向平均电流不超1A,单次浪涌不超30A,避免过载;
  2. 结温控制:电流接近1A时,需通过PCB铜箔、散热片控制结温≤125℃;
  3. 电压余量:实际反向电压不超额定值80%(800V),避免长期高压衰减;
  4. 焊接规范:焊接温度≤260℃,时间≤5秒,避免损坏封装;
  5. 存储条件:存储温度-55℃~+150℃,避免潮湿,存储期≤12个月。

本款1N4007整流二极管凭借稳定性能与广泛兼容性,是各类中低压整流电路的理想选型,可满足多数常规电子设备的基础整流需求。

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.
