SS14（FOSAN 富信）产品概述
一、产品简介
FOSAN（富信）SS14为SMA封装肖特基整流二极管，额定整流电流1A，反向耐压40V。肖特基结构带来低正向压降与快速恢复性能，适合要求低损耗与高开关频率的电源与整流场景。工作结温范围宽，-65℃至+150℃，可满足工业与汽车级环境需求。
二、主要电气参数
- 正向压降 Vf：约550mV @ 1A（典型值）
- 直流反向耐压 Vr：40V
- 反向电流 Ir：200μA @ 40V（在高温下反向泄漏会增大）
- 整流电流 If：1A（连续）
- 封装：SMA（表面贴装，适用于自动化贴片生产）
三、特点与优点
- 低正向压降，减小导通损耗，提高效率，特别适合低压大电流路径。
- 反向恢复快，适用于高频整流与开关电源二次整流。
- 宽温度范围，可靠性高，可在严苛环境长期工作。
- SMA封装便于手工与自动化搭配，散热/寄生电感在可接受范围内。
四、应用场景
- 开关电源（SMPS）次级整流与续流二极管
- 逆电保护、反接保护电路
- 低压降整流、功率路径选择
- 汽车电子、工业控制、通信供电模块等需稳定耐温的领域
五、设计与选用建议
- 注意反向漏电在高温下显著上升，若工作在高温或轻负载时需验证热平衡与静态损耗。
- 若长期近1A工作，建议在PCB上使用较大铜厚或散热铜箔，并考虑热孔连接至内层或底板。
- 对于更高电流或更低Vf需求，可考虑并联多只或选用更大封装的肖特基方案。
- 在高精度低电流应用中，反向漏电可能成为限制因素，必要时评估替代硅二极管或低漏型肖特基。
总体而言，FOSAN SS14以其低Vf、宽温度和通用SMA封装，适合大多数1A级低压整流与保护用途，是性价比较高的通用肖特基选择。

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.
