MURS320快恢复二极管产品概述

MURS320是扬杰电子(YANGJIE)推出的独立式快恢复/高效率二极管,采用SMC(DO-214AB)表面贴装封装,针对中低压高频整流场景优化,平衡了正向压降、反向恢复时间与电流容量,是消费电子、工业控制、光伏等领域的高性价比选型。

一、核心参数与性能指标

MURS320的关键参数围绕高频效率与可靠性设计,具体如下表所示:

参数分类 参数名称 数值 测试条件/说明 基本电气特性 直流反向耐压(Vr) 200V 最大持续反向电压 平均整流电流(Io) 3A 环境温度Ta=25℃下的连续电流 正向压降(Vf) 920mV 正向电流If=3A时的典型值 高频特性 反向恢复时间(Trr) 35ns 典型值(结合典型测试电路) 可靠性指标 反向漏电流(Ir) 5μA 反向电压Vr=200V时的最大值 非重复峰值浪涌电流(Ifsm) 100A 8.3ms单脉冲(不重复) 温度特性 工作结温范围(Tj) -55℃~+150℃ 最大结温Tjmax=150℃ 封装规格 封装类型 SMC(DO-214AB) 表面贴装,尺寸紧凑

核心参数亮点:35ns的反向恢复时间大幅降低高频开关损耗,920mV的低正向压降提升整流效率,100A浪涌能力增强过流防护,宽结温范围适配极端环境。

二、封装与可靠性设计

SMC(DO-214AB)封装是MURS320的核心设计之一,具备以下优势:

  1. 紧凑尺寸:封装体积约3.5mm×2.5mm×1.5mm,适配高密度PCB设计,满足小型化产品需求;
  2. 散热优化:表面贴装结构配合PCB铜箔可有效散发热量,支持150℃最大结温,避免高频应用下的热积累;
  3. 可靠性增强:低反向漏电流(5μA@200V)减少静态损耗,浪涌电流能力(100A)应对瞬间负载波动,宽结温范围适配工业现场、户外光伏等场景。

三、典型应用场景

MURS320的参数特性使其适用于以下高频整流场景:

  1. 开关电源(SMPS):小功率AC-DC电源的二次整流(如手机充电器、机顶盒电源),高频开关下低损耗提升效率;
  2. 光伏逆变器:微型逆变器或小型集中式逆变器的DC侧整流、辅助电源整流,宽温范围适配户外环境;
  3. 不间断电源(UPS):小功率UPS的整流电路,浪涌能力应对瞬间负载冲击;
  4. 工业控制:PLC、伺服驱动器的辅助电源整流,宽结温范围适应工业现场温变;
  5. 消费电子:LED驱动电源、便携式设备充电模块,紧凑封装满足小型化设计。

四、选型优势对比

与同类产品相比,MURS320具备明显的性能-成本平衡优势:

  • 对比普通整流二极管(如1N5408):反向恢复时间从数百ns降至35ns,高频损耗降低60%以上;正向压降低8%,效率提升显著;
  • 对比进口快恢复二极管(如某品牌MUR320):参数一致,但国产供应链稳定,价格更具竞争力,适合批量应用;
  • 封装优势:SMC贴片封装比DO-27插件封装体积小70%,适配自动化生产,降低PCB布局难度。

五、应用注意事项

为保证MURS320的稳定工作,需注意以下几点:

  1. 散热设计:PCB上需预留足够铜箔面积(建议≥10mm²),避免结温超过150℃;
  2. 电压限制:持续反向电压不得超过200V,瞬间浪涌电压需控制在额定范围内;
  3. 焊接工艺:采用回流焊(260℃/10s),避免手工焊接过热损坏器件;
  4. 电流降额:环境温度高于25℃时,需根据降额曲线降低最大电流(如Ta=100℃时,Io降至约1.8A)。

总结

MURS320作为扬杰电子的快恢复二极管,凭借高频性能优异、参数平衡合理、封装紧凑、性价比高的特点,成为中低压(≤200V)、中小电流(≤3A)高频整流场景的理想选择。其国产替代优势明显,适配消费电子、工业控制、光伏等多领域的批量应用需求,是工程师优化电源设计的可靠选型。

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.
