RS2M 快恢复高压整流二极管 产品概述

一、产品简介

RS2M 为独立式快恢复/高效率整流二极管,面向高压开关电源、逆变器与工业整流场景。该器件由 CJ(江苏长电/长晶)生产,采用 SMAG 封装,额定整流电流 2A,反向耐压高达 1kV,具备较低正向压降与可接受的反向恢复特性,适用于需要高电压耐受与较快恢复速度的应用场合。

二、主要电气参数

  • 二极管配置:独立式
  • 正向压降 Vf:1.3 V @ If = 2 A
  • 直流反向耐压 Vr:1000 V (1 kV)
  • 整流电流(平均正向电流):2 A
  • 反向电流 Ir:2.5 μA @ Vr = 1 kV
  • 反向恢复时间 Trr:500 ns
  • 非重复峰值浪涌电流 Ifsm:60 A
  • 工作结温范围 Tj:-55 ℃ ~ +150 ℃

三、产品特点与优势

  • 高电压耐受:1 kV 的反向耐压使 RS2M 可以在高压整流与高压降压应用中替代体积更大的器件,减小系统尺寸与成本。
  • 低正向压降:在 2 A 工作点正向压降仅约 1.3 V,有利于降低整流损耗与发热,提升整机效率。
  • 低漏电流:在最高额定反向电压下反向漏电仅 2.5 μA,适合高压输电及长时间待机场合。
  • 可控的快恢复性能:Trr = 500 ns,较普通快速二极管能更好地兼顾切换损耗与开关电磁干扰(EMI),适用于中频率开关环境。
  • 良好浪涌承受能力:Ifsm = 60 A,能承受短时浪涌与启动电流,提升系统可靠性。

四、典型应用场景

  • 开关电源整流输出/整流桥
  • 逆变器与变频器的整流/自由轮二极管
  • 高压电源、产业电源与照明电源(电子镇流器)
  • 脉冲电源、充电设备与电源模块保护
  • 通用高压整流与取样电路

五、热特性与使用建议

  • 请注意结温上限为 +150 ℃,实际应用中应留有余量,保证在最大工作电流与环境温度下结温不会超过安全范围。
  • 在 PCB 布局上,推荐增大焊盘铜厚与散热面,必要时在器件下方或附近增加散热铜箔或热孔以改善散热。
  • 对于频繁开关或高重复浪涌的应用,建议评估器件在目标频率下的温升与电磁干扰,必要时并联热阻更低的器件或增加缓冲网络以改善开关应力。
  • 安装时保证良好焊接质量,避免因过热导致封装或内部连接损伤。

六、可靠性与注意事项

  • 建议在出厂规格范围内使用,避免长期在极限电压、极限电流或极限结温下工作,以延长器件寿命。
  • 在高压应用中,注意绝缘间距与爬电距离设计,确保反向电压下电气安全。
  • 存储与运输时避免潮湿与剧烈振动,若需焊接回流,按厂家温度曲线进行,以免引起器件应力或性能退化。

七、典型电路与选型提示

  • 作为整流二极管:可直接用于高压直流输出整流,若需更低损耗可并联或选用更低 Vf 的肖特基,但在高压场合 RS2M 在漏电与耐压之间具有良好平衡。
  • 作为自由轮/反并联器件:在电机驱动或功率变换器中,500 ns 的 Trr 使其在中等开关频率下表现平衡,若系统对开关损耗极敏感,可考虑更快的快恢复或软恢复器件。
  • 选型提示:若工作电流持续大于 2 A,应选用额定电流更高的型号或采取并联方案;若工作开关频率显著高于数十 kHz,建议评估更短 Trr 的器件以降低开关损耗与 EMI。

八、订购信息

  • 型号:RS2M
  • 品牌:CJ(江苏长电/长晶)
  • 封装:SMAG
  • 如需样品或批量采购,请以型号 + 品牌 + 封装(例如 RS2M - CJ - SMAG)与供应商确认具体测试数据、封装图纸与回流焊工艺规范。

如需基于具体电路的热仿真、搁置时间/浪涌测试建议或替代型号推荐(更低 Vf / 更短 Trr / 更高 Ifsm),可提供详细应用工况(频率、占空比、环境温度、散热条件),我会给出针对性的选型与布局建议。

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.
