US2M 产品概述 — LGE(鲁光) 通用整流二极管（SMB封装）
一、产品简介
US2M 是鲁光（LGE）推出的一款独立式通用整流二极管，采用SMB封装，设计用于中等功率整流与开关应用。器件额定整流电流2A，直流反向耐压高达1kV，正向压降1.7V（在2A条件下），兼顾耐压与导通性能，适用于整流、续流与浪涌承受要求较高的电源电路。
二、主要电气参数
- 正向压降 (Vf)：1.7V @ If = 2A
- 额定整流电流：2A（直流）
- 峰值非重复浪涌电流 (Ifsm)：50A
- 反向耐压 (Vr)：1000V
- 反向电流 (Ir)：10µA @ Vr = 1000V
- 反向恢复时间 (Trr)：75ns
- 工作结温范围：-55°C ~ +150°C
- 封装：SMB（独立式）
三、产品特性与优势
- 高耐压：1kV 额定反向电压，适合高压整流与高压保护场合。
- 良好浪涌能力：50A 短时浪涌电流可承受启动或突波事件。
- 中等恢复速度：75ns 的反向恢复时间使其适用低至中频开关电源和整流应用，而无需极高速二极管的成本。
- 小封装大性能：SMB 封装兼顾散热与尺寸，方便自动化贴装与批量生产。
四、典型应用场景
- 开关电源（低到中频）整流与续流电路
- 工业电源、高压电源整流模块
- 逆变器保护、保护二极管与吸收回路
- 电机驱动中的过压与反向保护
- 浪涌吸收与一次侧整流
五、设计与安装建议
- 散热管理：尽量在PCB上增加焊盘铜箔面积并布置过孔，提升热扩散能力；SMB封装虽便于散热，但在2A连续工况下仍需注意铜箔厚度与面积。
- 布局要求：正负极走线尽量短且宽，减少寄生电感，降低开关时的过压与EMI。
- 频率匹配：反向恢复时间75ns适合低至中等开关频率；若频率较高或对开关损耗敏感，建议选用快恢复或肖特基二极管。
- 浪涌防护：若工作环境存在频繁或更大浪涌，请在输入端并联合适的浪涌抑制器或增加外部限流元件。
六、可靠性与使用注意
- 反向电流会随结温上升显著增加，设计时请留有余量并按照器件数据手册进行结温降额。
- 长时间在极限条件（高温、高电压）下工作会缩短寿命，建议遵守推荐的环境与散热条件。
- 储存与焊接：遵循常规焊接温度曲线，避免过度加热导致封装与键合线损伤。
七、采购与型号
品牌：LGE（鲁光）；封装：SMB；产品名称：US2M。具体订购规格、包装单位与认证资料请向鲁光授权分销或供应商索取完整数据手册和样片以便进行最终验证与可靠性试验。
如需样品测试、热仿真数据或与其他二极管型号的对比建议，可提供电路参数与工作工况，我方可给出更针对性的选型与布局方案。

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.
