RS1M 快恢复/高效率二极管 — JUXING(钜兴)

一、产品概述

RS1M 是钜兴(JUXING)推出的一款高电压、快恢复整流二极管,封装为 DO-214AC(SMA)。器件面向需要高反向耐压和中等开关速度的整流/开关场景,典型电气参数包括:直流整流电流 1A、正向压降 Vf = 1.3V(I_F = 1A)、直流反向耐压 VR = 1000V、反向电流 IR = 5 μA、非重复峰值浪涌电流 Ifsm = 30A 和反向恢复时间 Trr ≈ 500ns。工作结温范围为 -55°C ~ +150°C(Tj)。

二、主要性能特点

  • 高电压耐受:1kV 反向耐压,适合高压整流与保护应用。
  • 中等快速恢复:Trr 约 500ns,比普通整流二极管恢复更快,可降低开关损耗与电磁干扰(EMI)。
  • 低漏电流:5 μA 级别的反向电流,有利于高阻抗或高精度电路的漏电控制。
  • 良好浪涌能力:Ifsm=30A,可承受瞬态冲击,适用于含浪涌的负载。
  • 标准表面贴装:DO-214AC(SMA)封装,便于自动化贴装与可靠焊接。

三、典型应用场景

  • 高压整流电路(比如 HV 整流、仪器电源)
  • 开关电源(中低频开关域,需评估回收损耗)
  • 反并联/续流二极管与功率因数校正(PFC)的次级侧整流
  • 浪涌保护与反向电压保护电路
  • 工业与通信电源模块

四、电气与热特性说明(工程要点)

  • 正向压降 1.3V@1A 表示在连续整流工况下会有一定的导通损耗,热设计需考虑长时间功耗。
  • 500ns 的反向恢复时间适合中等频率开关;在较高频(数百 kHz 以上)场合,需评估恢复期间的开关损耗与应力,或考虑更快的超快恢复/肖特基替代器件。
  • 工作结温上限 150°C,保证良好的散热路径(PCB 铜箔、过孔或散热基板)能延长寿命并避免热退化。
  • 漏电流 5 μA 在高温时可能上升,需在高温工况下验证电路容忍度。

五、封装与安装建议

  • DO-214AC(SMA)为常用表贴封装,焊盘设计应保证足够的铜面积以扩散热量,并使用热过孔连接至底层散热铜箔。
  • 焊接工艺遵循回流温度曲线,避免超温和过长回流时间。
  • 布局上缩短高电流回路的走线,降低寄生电感;在高 dv/dt 场景考虑并联 RC 吸收或缓冲以降低尖峰应力。

六、使用注意与可靠性建议

  • 在含有高电压冲击或反复浪涌的环境中,应验证 Ifsm 与峰值能量承受能力是否满足实际工况。
  • 对于高频谐振/反复关断工作点,建议在样机上测量 Trr 相关的开关损耗与结温上升,必要时采用更快的器件或并联降压方案。
  • 储存与焊接时注意防潮与静电防护,常温下保存并按厂商推荐条件使用。

七、与同类器件比较与选型建议

RS1M 在高电压(1kV)和中等恢复速度(500ns)之间取得平衡,适合需要高耐压且对恢复速度有一定要求但不极端的应用。若追求更低正向压降或更快恢复,考虑肖特基或超快恢复(Trr < 100ns)系列;若耐压要求更低,可选更低 Vf 的器件以降低导通损耗。

八、订购信息

品牌:JUXING(钜兴);型号:RS1M;封装:DO-214AC(SMA)。在选型与采购前,请参考钜兴最新器件数据手册以获取完整的绝对最大额定值、典型曲线与焊接/可靠性规范。

如需基于具体应用做热仿真、开关损耗估算或替代器件推荐,可提供电路参数(开关频率、电流波形、环境温度、PCB 约束)以便进一步计算与建议。

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
