SBDD2045CT是富芯森美(FUXINSEMI) 推出的1对共阴极肖特基势垒二极管(SBD),采用TO-252贴片封装,针对低电压大电流整流场景优化设计,兼具低正向压降、高电流承载能力与宽温度适应性,是中小功率电源、电机驱动及车载电子等领域的实用型器件。
作为共阴极配置的肖特基二极管,SBDD2045CT内置2只同参数二极管(阴极共接),可灵活用于半桥整流、续流或钳位电路。其核心定位为中功率低损耗肖特基器件,区别于传统硅整流管,肖特基结构带来低正向压降特性,同时兼顾反向耐压与电流密度,满足现代电子设备对高效、紧凑设计的需求。
SBDD2045CT采用TO-252(D-PAK)贴片封装,具有以下优势:
适用于12V/24V输入的适配器、LED驱动电源等:低Vf特性减少电源损耗,20A电流能力满足大功率LED模组(如户外显示屏)供电需求,宽温范围适配工业照明场景。
在直流电机、步进电机驱动中作为续流二极管:肖特基二极管无反向恢复时间,可减少开关损耗;150A浪涌耐受能力抵御电机启动瞬间的大电流冲击,宽温范围适配工业机器人、电动车辅助电机等场景。
车载12V/24V电源系统中用于电源整流、过压保护:-55℃~+150℃宽温适配车载环境温度波动,45V耐压满足汽车电路瞬态电压要求,可靠性符合车载电子标准(如ISO 16750)。
在USB-PD快充(65W/100W)的低电压整流环节:低Vf提升快充效率,减少发热;20A电流能力支持多口快充的大电流输出,适合笔记本电脑、手机快充适配器。
富芯森美(FUXINSEMI)作为国内专注于功率半导体的厂商,SBDD2045CT具备高性价比、国产化替代优势:
综上,SBDD2045CT以其低损耗、高电流、宽温适应性与紧凑封装,成为低电压大电流整流场景的优选器件,覆盖消费电子、工业、车载等多领域应用需求。

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.
