SR260肖特基二极管产品概述

一、产品基本定位与标识

MDD品牌SR260是一款低压降轴向肖特基整流二极管,核心面向中小功率、低功耗的整流应用场景,兼顾宽温适应性与抗浪涌能力。型号命名遵循行业常规逻辑:SR代表肖特基整流(Schottky Rectifier),2对应额定整流电流(2A),60对应直流反向耐压(60V),封装为经典的DO-15插件形式。

二、核心电气参数解析

SR260的参数设计精准匹配低压整流需求,关键性能如下:

1. 正向压降与效率优势

正向压降(Vf)仅700mV@2A直流,是普通硅整流管(通常1V以上)的1/2左右,可显著降低整流过程中的功率损耗。例如在5V输出的电源中,压降占比从传统硅管的20%降至14%,直接提升电源转换效率。

2. 反向耐压与漏电控制

  • 直流反向耐压(Vr):60V,满足12V、24V等低压直流系统的耐压需求,无需额外降额设计;
  • 反向电流(Ir):500μA@60V常温,漏电控制在较低水平,长期工作时不会因漏电导致额外发热或功耗增加,保障电路稳定性。

3. 电流承载与浪涌能力

  • 额定整流电流(Id):2A直流,可稳定承载中小功率电路的持续电流;
  • 非重复峰值浪涌电流(Ifsm):60A(8.3ms半波),能有效应对电源启动、负载突变等瞬间大电流冲击,降低器件失效风险(如开机瞬间的浪涌电流通常在10-30A,60A余量可覆盖多数场景)。

4. 宽温适应性

工作结温范围为**-65℃+150℃**,覆盖工业级(-40+85℃)、消费电子甚至部分汽车电子(-40~+125℃)的温度需求,可在极端环境下稳定工作。

三、封装与机械特性

采用DO-15轴向引线封装,是电子行业经典的小功率插件封装形式,具备以下特点:

  • 体积紧凑:直径约2.5mm,长度约5mm,适合空间受限的电路设计;
  • 引脚可靠:通常采用镀锡处理,焊接性好、耐氧化,长期使用不易出现引脚腐蚀;
  • 安装便捷:无需特殊贴片设备,手工或自动插件均可实现,适配多数传统PCB板设计;
  • 机械强度:封装外壳采用耐高温工程塑料,能承受常规机械应力与环境冲击。

四、典型应用场景

SR260的参数匹配性使其在多个领域广泛应用,核心场景包括:

  1. 开关电源输出整流:5V/2A、12V/2A的AC-DC适配器、DC-DC模块,利用低压降提升效率;
  2. 低压直流系统:12V/24V汽车辅助电路(车载充电器、传感器供电)、工业控制板小功率电源;
  3. 小型充电设备:手机、平板充电器的次级整流,或充电宝升压/降压电路辅助整流;
  4. 信号整流:低电压传感器输出信号的直流化处理,避免压降过大导致信号失真。

五、产品优势总结

  • 效率优先:700mV低压降大幅降低整流损耗,适合对效率敏感的低功耗场景;
  • 可靠性突出:宽结温、低漏电、60A浪涌能力,保障长期稳定工作;
  • 易用性强:DO-15封装插件方便,无需特殊工艺;
  • 性价比高:性能优于同参数普通硅管,成本控制合理,适合批量应用。

SR260凭借均衡的性能与成本优势,成为中小功率低压整流场景的经典选择,广泛应用于消费电子、工业控制、汽车电子等领域。

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
