这款由台冠电子(TDD)推出的SS24,是一款针对低压电路优化的SMA封装肖特基整流二极管,凭借低正向损耗、宽温适应性及抗浪涌能力,成为消费电子、工业辅助电路等领域的常用选型。
SS24属于肖特基势垒二极管,核心优势来自金属-半导体接触结——区别于普通硅整流管的PN结,这一结构让它在保持2A级电流承载的同时,实现更低正向压降与更快开关速度。设计针对40V耐压的低压场景,主打高效能量转换与小型化布局。
正向压降(Vf)仅700mV@2A——远低于普通硅管(如1N4007在1A下Vf约1V),相同电流下导通损耗降低30%以上,能有效减少电路发热,提升电源转换效率。
SS24采用SMA封装(DO-214AC),尺寸仅约3.2mm(长)×2.2mm(宽)×1.6mm(高),体积小巧,可大幅节省PCB空间,适合高密度贴装。
封装材料为耐高温环氧树脂,具备防潮、抗机械应力能力;引脚采用铜基镀锡工艺,焊接兼容性强(回流焊峰值温度≤260℃,焊接时间≤10s),避免热损伤影响可靠性。
整体来看,TDD SS24以均衡的性能、小巧封装及高可靠性,成为低压2A级整流/续流应用的高性价比选型,适合量产电路的成本与性能平衡需求。

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.
