RS3M-SMB快恢复/高效率二极管产品概述

一、产品定位与核心类别

RS3M-SMB是一款快恢复/高效率功率二极管,采用独立式结构设计,专为高频开关电源、高压整流、工业控制等场景中的低损耗、快速切换需求打造。作为功率半导体核心器件,其核心功能是实现单向电流导通,同时通过快恢复特性适配高频工作环境,兼顾效率与可靠性,是中小功率电源设计的优选器件。

二、关键性能参数详解

RS3M-SMB的参数经过针对性优化,满足多场景应用需求,核心指标及意义如下:

  • 正向压降(Vf):1.3V@3A,额定电流下保持低导通损耗(3A时功耗仅3.9W),显著提升电源转换效率,减少器件发热;
  • 直流反向耐压(Vr):1kV,支持高压输入场景(如AC220V/380V电网、光伏高压阵列),反向偏置时不击穿,保障电路安全;
  • 连续整流电流(If):3A,可稳定承载3A连续正向电流,适配≤1kW的中小功率电源设计;
  • 反向漏电流(Ir):5μA@1kV,反向偏置时漏电流极小,降低待机损耗,避免器件因漏电流发热老化;
  • 反向恢复时间(Trr):500ns,属于快恢复范畴(比普通整流管快40%以上),适合100kHz+高频开关场合,减少开关损耗与电磁干扰;
  • 工作结温范围:-65℃~+150℃,宽温设计适应极端环境(如工业低温、户外光伏高温),提升长期可靠性;
  • 非重复峰值浪涌电流(Ifsm):100A,可承受瞬间大电流冲击(如开机浪涌、雷击),保护电路不受损坏。

三、封装设计与应用特性

RS3M-SMB采用SMB(DO-214AA)表面贴装封装,具备以下设计优势:

  • 体积小巧:封装尺寸约2.9×3.8×1.5mm,节省PCB空间,适配高密度电路设计;
  • 贴装高效:符合SMT自动化生产要求,降低人工成本与焊接难度,提升生产效率;
  • 独立式结构:安装灵活,可单独使用或与其他器件组合成整流桥,适配半桥、全桥等多种电路拓扑;
  • 多特性兼顾:快恢复+低压降+宽温范围+高浪涌抗扰,平衡高频性能与效率,满足复杂场景需求。

四、典型应用场景

RS3M-SMB的参数特性使其广泛应用于以下领域:

  1. 开关电源:AC-DC适配器(笔记本、手机充电器)、DC-DC转换器的整流/续流级;
  2. 光伏逆变器:光伏板输出DC转换为AC的前端整流电路,适配高压光伏系统;
  3. UPS不间断电源:市电切换时的整流/逆变模块,减少切换损耗与响应时间;
  4. LED驱动电源:高压输入(100-240VAC)LED驱动的整流级,支持多串LED并联;
  5. 工业控制:PLC、伺服驱动器、变频器的电源模块,适应工业现场-40℃~85℃宽温环境;
  6. 消费电子:智能家电(空调、电视)的电源电路,提升能效等级,降低待机功耗。

五、品牌与可靠性保障

RS3M-SMB由GOODWORK(固得沃克) 生产,该品牌是国内专注功率半导体的专业厂商,产品具备:

  • 环保合规:符合RoHS、REACH等国际环保标准,采用无铅焊接工艺;
  • 质量认证:通过ISO9001质量管理体系认证,参数一致性好,批次差异小;
  • 可靠性测试:经过高低温循环、浪涌冲击、反向耐压等严格测试,保障10万小时以上工作寿命;
  • 技术支持:提供电路设计参考、样品测试与售后技术服务,降低客户研发难度。

RS3M-SMB凭借快恢复、低损耗、宽温特性,成为高频开关电源、高压整流等场景的高性价比选择,适配多行业的功率转换需求。

BOM matching & alternatives

BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.

Electronic component sourcing availability dashboard with ESD-protected samples

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
