FR2WSMA 产品概述
一、产品简介
FR2WSMA 为 DIOTEC（德欧泰克）推出的一款高速恢复整流二极管，采用 SMA（DO-214AC）贴片封装，设计用于高电压、开关频率较高的整流与保护场合。器件在2A整流电流工况下表现稳定，同时具备高达1.6kV的反向耐压，适合中高压电源与变换器应用。
二、主要参数
- 工作结温范围：-50℃ ~ +150℃
- 直流整流电流（IF(AV)）：2A
- 正向压降（Vf）：1.8V @ 2A
- 非重复峰值浪涌电流（IFSM）：50A
- 直流反向耐压（VR）：1600V
- 反向电流（IR）：5μA @ 1600V
- 反向恢复时间（Trr）：500ns
- 封装：SMA (DO-214AC)
三、关键特性与优势
- 高耐压：1600V 反向耐压使器件适用于高压整流与保护电路。
- 抗浪涌能力良好：50A 峰值浪涌电流满足短时冲击电流要求。
- 快速恢复：500ns 的反向恢复时间降低开关损耗与关断时的电磁干扰。
- 低漏电：在额定高压下反向漏电仅约5μA，有利于提高系统空载效率。
- 紧凑封装：SMA 表面贴装便于自动化组装与高密度板级设计。
四、典型应用
- 高压整流电源与逆变器二次侧整流
- 开关电源（SMPS）与功率因数校正（PFC）电路
- 高压检测、偏置电路及保护二极管
- 工业电源、测量仪器及铁路、通信设备等高压场景
五、封装与安装建议
- SMA（DO-214AC）为常用SMD封装，适配贴片回流焊工艺；建议按厂家推荐的焊接曲线与PCB焊盘设计进行组装。
- 为保证长期可靠性，应在布局中为二极管提供足够的散热铜箔和热流通道，避免长时间高结温运行。
- 对于可能发生的浪涌或重复脉冲，建议在系统设计中配合限流或浪涌抑制措施，避免超过 Ifsm 规格。
六、可靠性与使用注意
- 器件工作结温虽支持最高150℃，但为延长寿命与提高稳定性，推荐在设计中留有温升余量并进行必要的降额使用。
- 反向漏电随温度上升而增加，高温工况下应重视漏电对系统空载及待机功耗的影响。
- 非重复峰值浪涌为瞬态能力，不代表可长期承受的脉冲负载，重复冲击需按数据手册要求评估。
七、选型与采购
FR2WSMA 为 DIOTEC 品牌型号，适用于需要兼顾高压耐受与快速恢复特性的场合。具体包装方式、最小订购量和器件认证信息建议向 DIOTEC 或授权分销商索取数据手册与样片，以便在电路设计和可靠性验证阶段完成详细确认。

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.
