RS3MB 产品概述 — JUXING(钜兴) 快恢复/高效率二极管

一、产品简介

RS3MB 是钜兴(JUXING)推出的一款功率型快恢复/高效率整流二极管,采用 SMB 封装,面向高压、大电流整流与开关应用。该器件在 3A 持续整流电流下具备较低正向压降(Vf),并兼顾高耐压与较短的反向恢复时间(Trr),适用于高压开关电源、逆变器、整流桥及工业电子类设备的整流与回续保护场景。

二、主要特性

  • 工作结温范围:-55℃ ~ +150℃(Tj)
  • 正向压降:Vf = 1.3V @ If = 3A
  • 直流反向耐压:Vr = 1kV(1000V)
  • 反向电流:Ir = 5µA @ Vr = 1kV
  • 非重复峰值浪涌电流(Ifsm):100A(单次冲击能力)
  • 反向恢复时间:Trr = 500ns(快恢复特性)
  • 额定整流电流:3A(连续)

三、产品优势(要点)

  • 高耐压能力(1kV)满足高压整流与阻断需求,适合中高压电路。
  • 低正向压降(1.3V@3A)在直流整流工况下降低导通损耗,提高效率。
  • 反向电流低(5µA@1kV),在高压下泄漏小,有利于降低待机与静态功耗。
  • 500ns 的反向恢复时间在高频切换中可减少切换损失及电磁干扰,相较传统整流器件具备更好开关性能。
  • SMB 封装兼顾散热与体积,便于波峰/回流焊接与自动化贴装。

四、典型应用

  • 开关电源(SMPS)整流与二次侧回续二极管
  • 高压整流与整流桥
  • 逆变器与不间断电源(UPS)
  • 马达驱动与伺服控制电路的续流保护
  • 充电设备、太阳能逆变与照明镇流器等需高压整流的场合

五、设计与使用要点

  • 虽然器件额定连续电流为 3A,但实际散热与板上铜箔面积、环境温度、通风条件直接影响允许的长期电流,应根据 PCB 热仿真或厂家热阻与降额曲线设计散热措施。
  • Ifsm = 100A 表示能承受短时间浪涌(例如充电、浪涌冲击),但不等同于可长期承受的重复脉冲,设计时应避免频繁大幅浪涌。
  • 反向恢复时间 500ns 对于中高频率开关电路已具备优势,但在极高开关频率或对 EMI 要求极严的场合,仍需评估是否需结合软恢复或额外抑制网络。
  • 反向漏电随温度上升而增加,长时高温工作应关注漏电与热失控风险,并考虑适当的温度保护与安全裕度。

六、封装与可靠性

SMB 封装便于自动化贴装并具有一定的散热能力。器件的工作结温范围扩展至 -55℃ 至 +150℃,适应工业级与汽车级环境。实际可靠性还依赖于生产批次与出货前的品质控制,建议在批量设计前索取完整数据手册与可靠性测试报告(如热循环、湿热与寿命加速试验)。

七、结论与推荐

RS3MB(JUXING 钜兴)为需要在中高压环境下实现高效率整流与较快开关性能的应用提供了一种性价比较高的解决方案。其 1kV 的耐压能力与较低的正向压降、适宜的反向恢复时间,使其在开关电源、逆变与高压整流场合具备良好适配性。建议在使用前参照完整规格书进行热设计与浪涌评估,以确保长期可靠运行。若需进一步数据(如热阻、封装尺寸或测试波形),可向供应商索取 RS3MB 的详细资料与样品验证。

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
