SS1040B 是晶导微电子推出的一款高电流表面贴装二极管,采用金属-硅结结构(Metal-Silicon junction),属于多数载流子传导器件。器件以 SMB 封装提供,专为低压、高频开关场合设计,兼顾低功耗与高浪涌承受能力,适用于功率整流、续流以及极性保护等场景。
注:正向压降随电流和结温变化,给出的 0.55 V 为在 10 A 条件下的参考值;使用时应参考完整数据手册中的 Vf–If 曲线与热阻数据进行热设计和裕量计算。
如需器件封装尺寸、焊盘推荐图、Vf–If 曲线或更详细的耐浪涌、热阻数据,我可以根据晶导微电子的完整版技术资料为您整理出具体的设计指导和 PCB 布局建议。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
