FR1MD3 产品概述
一、产品简介
FR1MD3 是富芯森美（FUXINSEMI）推出的一款独立式快恢复/高效率整流二极管，采用 SOD-323 小型表面贴装封装。该器件针对中等功率、高耐压场合优化，兼顾开关速度与低漏电特性，适用于各种高压整流与开关电源应用。
二、主要特点
- 额定整流电流：1A（连续）
- 反向耐压（Vr）：1000V，适合高压整流与保护用途
- 正向压降（Vf）：1.3V @ 1A，导通损耗可控
- 反向电流（Ir）：5μA @ 1kV，低漏电利于高压下的能耗控制
- 反向恢复时间（Trr）：500ns，属于快恢复等级，适配开关频率适中的电路
- 工作结温范围：-55℃ ~ +150℃，耐环境能力强
- 封装：SOD-323，低高度、适合密集布局与自动贴装生产
三、主要电气参数（概要）
- 最大重复反向电压：1000V
- 连续正向整流电流：1A
- 正向电压：典型 1.3V @ 1A
- 反向泄漏电流：典型 5μA @ 1000V
- 反向恢复时间：500ns（典型）
（详细极限值与温度依赖特性请参阅器件数据表）
四、典型应用场景
- 开关电源（SMPS）次级整流与高压整流
- 逆变器与电机驱动的高压回路保护
- 高频开关器件的缓冲与续流二极管
- 光伏、充电桩等需要高耐压、低漏电的电路
- 高压测量、电源取样与整流模块
五、封装与热管理
SOD-323 为低成本、低剖面表贴封装，便于自动贴片与回流焊接。由于器件额定整流电流为1A，设计时应考虑PCB铜箔扩展和散热路径，以保证器件在1A工作下处于安全结温范围内。并避免长期在高结温附近工作以延长寿命。
六、可靠性与使用注意
- 尽量在额定参数范围内使用，避免重复大电流浪涌或超额反向电压冲击。
- 在高压侧使用时注意爬电与绝缘要求，保证足够的间距与防护。
- 回流焊工艺应遵循封装规范，避免过高回流峰值温度或超时焊接。
- 对ESD 敏感线路做好防护，实际应用中建议结合熔断与限流器件提高可靠性。
七、推荐电路与工程建议
- 用作整流时，可搭配适当滤波电容与限流电阻以减少峰值应力。
- 在开关电源的续流或二极管箝位位置，FR1MD3 可替代普通慢恢复二极管以降低开关损耗与振铃，但在高频（>200kHz）场合需验证Trr对效率与电磁兼容的影响。
- 高压设计推荐进行温升测试，必要时采取散热铜箔或热 vias。

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.
