SS320 肖特基二极管（LGE 鲁光）产品概述
一、产品简介
SS320 为 LGE（鲁光）生产的一款独立式肖特基整流二极管，封装为 SMB（DO-214AA）。该器件在高达200V的反向电压下，提供最高3A的连续整流能力，正向压降在3A时约为0.84V，适合中高压整流与开关电源的整流与保护用途。
二、主要参数
- 正向压降（Vf）：0.84V @ 3A
- 最大整流电流：3A（直流）
- 直流反向耐压（Vr）：200V
- 反向漏电流（Ir）：100µA @ 200V（典型/测试条件）
- 封装：SMB（DO-214AA），适用于表面贴装工艺
三、特点与优势
- 低正向压降：在大电流条件下仍能保持较低压降，降低整流损耗。
- 低反向恢复：肖特基结构带来极小的反向恢复特性，适合高频开关应用。
- 高耐压版本：200V 的反向耐压在肖特基中属高压型号，扩展了其在中高压电路的应用范围。
- SMB封装：体积适中、散热和焊接性能平衡，便于自动贴片装配。
四、典型应用
- 开关电源输出整流、二次侧整流
- DC-DC 转换器、降压/升压模块中的肖特基整流
- 车载电源、太阳能逆变器和工业电源的保护与整流
- 反向电池保护、ORing 电路及续流二极管
五、热管理与使用建议
3A 条件下的正向损耗约为 P = Vf × I = 0.84V × 3A ≈ 2.52W，散热需求较大。建议：
- 在 PCB 设计中增大铜箔散热面积并使用热过孔；
- 在高环境温度或持续满流工作时进行电流/功耗降额；
- 注意反向漏电随温度上升显著增加，应在高温工况下评估漏电对系统的影响。
- 对可能的浪涌电流采取限流或熔断保护。
六、封装与采购注意
SMB（DO-214AA）为表贴封装，请根据回流焊工艺调整焊盘与温度曲线。采购时确认 LGE（鲁光）原厂或授权分销商货源，并索取完整规格书，核实最大结温、脉冲浪涌电流、封装尺寸及可靠性测试数据。
若需针对具体电路的选择建议（如频率、占空比、热沉设计），可提供工作条件以便进一步计算与推荐。

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.
