扬杰SR5200肖特基二极管产品概述

扬杰电子推出的SR5200是一款独立式轴向直插肖特基整流二极管,采用DO-27(国际编号DO-201AA)封装,针对低电压大电流整流场景优化设计,具备正向压降低、开关速度快等肖特基二极管典型优势,同时兼顾宽温工作与浪涌耐受能力,适用于多种工业及消费类电子领域。

一、产品核心参数详解

SR5200的关键电气参数明确了其性能边界,具体如下:

  1. 正向压降(Vf):典型值850mV(测试条件:正向电流IF=5A,结温25℃)——相比传统硅整流管(正向压降约1V以上),低压降可有效降低整流损耗,提升电源效率;
  2. 直流反向耐压(Vr):额定值200V——满足多数中低压整流电路的反向耐压需求,避免反向击穿;
  3. 平均整流电流(IF(AV)):额定值5A——环境温度25℃、散热良好时,可长期稳定输出的平均正向电流;
  4. 反向漏电流(Ir):典型值100μA(测试条件:反向电压Vr=200V,结温25℃)——肖特基二极管漏电流略高于硅整流管,但仍在可控范围,高温下漏电流会略有上升(需注意散热);
  5. 工作结温范围:-55℃~+150℃——宽温设计适配极端环境(如车载、户外设备),高低温下性能稳定;
  6. 非重复峰值浪涌电流(Ifsm):额定值120A(测试条件:8.3ms半波脉冲,结温25℃)——可承受瞬间大电流冲击(如开机浪涌、负载突变),提升电路可靠性。

二、封装与引脚识别

SR5200采用DO-27轴向直插封装,属于标准通孔插件封装,特点如下:

  • 尺寸紧凑,适配PCB插件工艺,安装便捷;
  • 引脚数为2,分别为阳极(A) 和阴极(K);
  • 引脚识别:阴极端通常带有色环标识(如白色/黑色环),可快速区分正负极,避免反向接入损坏器件。

三、典型应用场景

结合参数特性,SR5200主要应用于:

  1. 开关电源整流:笔记本适配器、LED驱动电源、小型开关电源的低压输出整流,利用低压降降低损耗;
  2. 续流二极管:电机、电感等感性负载的续流电路,快速关断特性减少反向电压尖峰;
  3. 车载电子:车载充电器、照明电路的整流/续流,宽温范围适配车载环境(-40℃~85℃);
  4. 低压直流电路:电池充电、DC-DC转换器输出整流,满足低电压(5V/12V)大电流需求;
  5. 工业控制:小型工业电源、传感器电路的整流环节,浪涌耐受能力适配工业现场。

四、使用注意事项

确保器件可靠性需注意:

  1. 散热设计:平均电流接近5A时,需配合散热片(DO-27封装散热有限),避免结温超150℃;
  2. 焊接规范:焊接温度≤260℃,时间≤10秒,避免高温损坏;
  3. 静电防护:肖特基对静电敏感,操作需戴防静电手环、用防静电工具;
  4. 电压限制:反向电压不得超200V,避免击穿;
  5. 浪涌限制:非重复浪涌≤120A,两次浪涌间隔需>10秒。

五、同类产品优势对比

相比同封装同参数的传统硅整流管(如1N5408),SR5200优势:

  • 正向压降低20%以上,效率提升明显;
  • 开关速度达ns级,适配高频电路;
  • 宽温范围更宽,适应极端环境。

扬杰SR5200凭借稳定性能与成熟封装,成为中低压大电流整流场景的高性价比选择,广泛应用于消费电子、车载、工业等领域。

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
