SS310B 为 FOSAN(富信)出品的肖特基(Schottky)整流二极管,封装为 SMB(常见的 DO-214AA 形式),设计用于中高电流整流及开关电源应用。其主要电气参数为:正向压降 Vf = 0.85V(在 3A 条件下);直流反向耐压 Vr = 100V;额定整流电流 3A;反向漏电流 Ir ≤ 20μA(在 100V);工作结温范围 −65℃ ~ +150℃。该器件兼顾低正向压降与较高反向耐压,适合要求效率与耐压并重的场景。
SS310B 适合在需要兼顾较低正向压降与 100V 级耐压的场合使用。选型时若需更低 Vf 可考虑更高性能的肖特基系列;若需更高耐压应选择额定 Vr 更高的型号。替代器件在选用时需匹配关键参数:Vr、If(平均整流电流)、Vf@If、Ir@Vr、封装及工作温度范围。
如需更详细的参数曲线(正向特性随温度变化、反向特性曲线、脉冲测量条件等)或参考电路与封装尺寸图,可提供具体需求,我将为您补充对应的技术资料。

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.
