RS3M 产品概述
一、产品简介
RS3M 为 TWGMC（台湾迪嘉）推出的独立式整流二极管，采用SMC（DO-214AA）封装，面向需要高耐压和中等整流电流的电源与整流应用。器件在3A直流整流电流条件下正向压降约为1.3V，最高直流反向耐压可达1000V，适合高压整流场合。
二、主要电气参数
- 正向压降 (Vf)：1.3V @ 3A
- 直流反向耐压 (Vr)：1000V
- 直流整流电流：3A
- 反向电流 (Ir)：5µA（典型/测试条件下）
- 反向恢复时间 (Trr)：500ns
- 非重复峰值浪涌电流 (Ifsm)：90A（非重复冲击能力）
- 工作结温范围：-55℃ ~ +150℃（Tj）
三、产品特性与影响要点
- 高耐压：1000V 规格适合高压整流、HV 电源及离线应用。
- 中等整流能力：3A 连续电流适用于小功率开关电源、充电器与整流桥。
- 正向压降较高：3A 时约1.3V，功耗相对显著（P≈Vf×I），须重视散热设计。
- 反向恢复时间 500ns：属普通恢复二极管，开关频率较高（数十kHz 以上）时会产生较大开关损耗与电磁干扰，非高频快速恢复或肖特基替代品。
- 峰值浪涌能力：90A 能承受短时浪涌，但为非重复指标，需按实际浪涌能量与热应力评估。
四、典型应用场景
- 高压整流桥与续流二极管（离线电源、适配器）
- 工业电源、变频器的整流与保护回路
- 家电与照明电源中的功率整流
- 需要高耐压且允许中等开关速度的场合
五、设计与使用建议
- 热管理：在连续3A工作下需在PCB上保留充足铜箔与散热面积，必要时并联或采用散热片。
- 开关频率考量：若工作在高开关频率或软开关场合，建议采用快恢复或肖特基器件以降低开关损耗和EMI。
- 浪涌与过载保护：设计时考虑Ifsm 非重复限制及反复浪涌对器件寿命的影响，配合熔断器或电流限制电路。
- 焊接与存储：遵循SMC封装通用的回流焊工艺与防潮处理，避免超过规格温度和湿度条件。
总结：RS3M 为一款高耐压、适用于中等功率整流的通用二极管，适合要求1000V 耐压且对开关速度没有严格要求的电源与整流应用。选择时应结合工作频率、散热条件和浪涌需求进行综合评估。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
