SS310是台冠电子(TDD)推出的一款3A/100V肖特基整流二极管,采用SMA(DO-214AC)贴片封装,主打「小体积+低导通损耗+高电流密度」三大核心优势。区别于传统硅整流管,其正向压降(Vf)仅850mV@3A,可显著降低导通损耗;同时兼顾100V反向耐压与3A持续整流能力,适配多种中小功率整流/续流场景,是替代老旧硅管的高性价比方案。
SS310的正向压降(Vf)在3A工作电流下仅为850mV——这一参数直接决定导通损耗:相同电流下,低Vf可减少功耗、降低发热,尤其适合开关电源等对效率敏感的应用。需注意:Vf随结温略有下降(结温每升10℃,Vf约降2mV),但仍保持在低损耗区间,不影响整体效率。
工作结温覆盖**-55℃~+125℃**,符合工业级温度标准,可在极端环境(如车载-40℃高温、户外低温)下稳定工作,无需额外降额。
SS310采用SMA超小型贴片封装(尺寸约2.7×1.6×1.1mm),具备以下优势:
SS310的参数特性使其在多领域广泛落地:
SS310是一款平衡「效率、体积、可靠性」的中小功率肖特基整流二极管,尤其适合对功耗敏感、空间紧凑的应用场景,是台冠电子在低压整流领域的经典型号,可替代市场上同规格竞品(如SS310),具备高性价比优势。

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.
