SS320 产品概述
一、产品简介
SS320 为 GOODWORK（固得沃克）系列肖特基整流二极管，属于独立式封装器件，采用 SMA（DO-214AC）封装。该器件在高压条件下依然保持较低的正向压降和可控的反向漏流，适合需要高耐压与高效率兼顾的电源与保护应用。
二、主要电气参数
- 正向压降（Vf）：0.92V @ IF = 3A（典型）
- 直流反向耐压（Vr）：200V
- 额定整流电流（IF）：3A（连续）
- 反向电流（IR）：20µA @ VR = 200V
- 非重复峰值浪涌电流（Ifsm）：80A（一次冲击）
- 工作结温范围：-65℃ ~ +175℃
三、封装与热性能
SMA（DO-214AC）封装体积小、安装方便，适合中等功率密度的贴片应用。建议在印制板上使用较大铜箔散热区并布置热过孔以降低结温。连续3A工作时需考虑环境散热条件并适当派生散热策略以避免过热降额。
四、产品特性与优势
- 肖特基结构带来较低的正向压降，有助于降低导通功耗，提高整机效率。
- 200V 的反向耐压水平使其能在高压输入的电源和保护电路中工作，扩展了应用场景。
- 反向漏流在200V时为20µA，保持在可控范围，适用于大多数整流与整流保护场合。
- 抗浪涌能力（Ifsm=80A）足以应对开机浪涌或短时过载事件。
五、典型应用场景
- 开关电源（AC-DC、DC-DC）整流与续流（freewheeling）
- 输入过压/反向保护、极性保护电路
- 功率模块的输出整流、二极管耦合与隔离
- 电池充电管理中作为快恢复/低损耗整流元件
六、选型与使用建议
- 在高温或高正向电流工况下，Vf 与 IR 会上升，设计时应留有余量并考虑降额使用。
- 高频开关环境下注意栅极/走线布局以降低寄生电感，必要时配合阻尼或吸收网络抑制峰值应力。
- 若需更低漏电以用于高阻应用，或更高耐压/电流等级，请对比同系列或替代型号。
- 并联使用时注意电流均分问题，应匹配热阻和走线以避免单只器件过载。
七、存储与可靠性注意
- 遵循常规贴片元件存储条件，避免潮湿、酸碱性环境，焊接前若为长期存储应进行烘烤除湿处理（参考厂家推荐）。
- 装配时遵守回流焊温度曲线，避免超出器件最高结温。
SS320 以其较高的耐压、高浪涌承受力和合理的正向压降，在需要兼顾效率与耐压的中小功率电源与保护电路中，是一款实用且可靠的选择。若需更详细的电气特性曲线或封装尺寸，请参考厂家数据手册或联系供应商获取完整资料。

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.
