MURS120T3G 快恢复/高效率二极管产品概述

一、产品定位与核心特性

MURS120T3G是杰盛微(JSMSEMI)推出的SMB封装快恢复/高效率二极管,主打中小功率高效整流场景。其核心优势在于平衡了「低导通损耗」与「快开关响应」,同时具备宽温适应性和强浪涌耐受能力,可满足开关电源、LED驱动等领域对稳定高效整流的需求。

二、关键电气参数深度解析

该器件的参数经过针对性优化,兼顾性能与可靠性,核心指标如下:

  • 正向压降(Vf):875mV@1A——远低于普通硅整流二极管(通常≥1V),可显著降低整流过程中的导通损耗,提升电源转换效率;
  • 直流反向耐压(Vr):200V——覆盖中低压(≤200V)电路的反向阻断需求,适配多数消费电子、通信设备的电源电压范围;
  • 持续整流电流(If):2A——支持2A以下连续工作电流,适配中小功率电源设计;
  • 反向漏电流(Ir):2μA@200V——漏电流极小,反向阻断性能优异,长期工作时发热少、稳定性高;
  • 反向恢复时间(Trr):35ns——属于快恢复二极管范畴,可有效减少高频开关过程中的反向恢复损耗,适合几十kHz的高频应用;
  • 非重复峰值浪涌电流(Ifsm):40A——能承受瞬间过流冲击(如开机浪涌、负载突变),提升电路抗干扰能力;
  • 工作结温范围:-65℃~+175℃——宽温设计,可适应车载、工业控制等高低温环境。

三、封装形式与物理特性

MURS120T3G采用SMB(DO-214AA)贴片封装,具备以下特点:

  • 尺寸紧凑:无引脚突出的贴片式设计,适合高密度PCB布局,节省板级空间;
  • 散热优势:SMB封装热阻较低,配合PCB铜箔可有效散发布尔效应产生的热量;
  • 工艺兼容:符合SMT自动化生产要求,支持高速贴装,降低人工成本。

四、可靠性与环境适应性

该器件的可靠性设计针对恶劣工况优化:

  • 宽温耐受:-65℃~+175℃的结温范围,可在低温(如北方户外设备)、高温(如电源密闭空间)环境下稳定工作;
  • 浪涌防护:40A非重复浪涌电流能力,可抵御电路中的瞬间过流,减少器件损坏风险;
  • 低漏电流:2μA@200V的反向漏电流,长期工作无明显发热累积,延长器件寿命。

五、典型应用场景推荐

结合参数特性,MURS120T3G适用于以下场景:

  1. 开关电源:高频AC-DC、DC-DC转换器的整流级,利用35ns快恢复特性减少开关损耗;
  2. LED驱动电源:低Vf降低导通损耗,提升LED驱动效率,适合小功率LED照明;
  3. 车载电子:宽温设计适配车载环境(-40℃~+85℃),用于车载充电器、中控电源;
  4. 通信设备:基站、路由器等设备的辅助电源,满足低功耗、高稳定性要求;
  5. 适配器:手机、笔记本电脑适配器的整流部分,适配2A以下输出电流需求。

总结

MURS120T3G通过优化正向压降、反向恢复时间与可靠性参数,成为中小功率高效整流的高性价比选择。其SMB封装的紧凑性、宽温适应性与强浪涌能力,可覆盖消费电子、车载、通信等多领域应用,为电源设计提供稳定可靠的整流方案。

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
