SBDD20200CT 是江苏长电/长晶(CJ)生产的一款高压肖特基整流二极管,双芯片封装为1对共阴极结构,适用于大电流、高压情形下的整流与保护应用。器件采用 TO-252-2(DPAK)表面贴装封装,兼顾功率散热与板级组装便利性,适合模块化电源、逆变与工业驱动方向的批量生产使用。
以上参数表明该器件在200 V 级别下能承受较高正向电流,并且具有较小的反向漏电,可用于要求高压耐受与较大脉冲能力的场合。
SBDD20200CT 采用 TO-252-2(DPAK)封装,适合回流焊贴装,具有较好的焊盘面积便于热量传导。由于器件额定整流电流达到 20 A,实际PCB设计时应配合足够铜厚与热铜铺设、通过热孔或散热片加强散热,以降低结温并保证长期可靠性。具体热阻与结温-环境的关系请参考器件完整数据表进行热设计与降额。
在选型时应结合系统最大工作电压、峰值浪涌需求与结温范围做热降额计算,并建议参考 CJ 提供的完整数据表与封装机械图以确认焊盘尺寸与可靠性。对于要求更低正向压降或更高电压的应用,可对比其他型号或咨询供应商获取备选方案。若关注长期寿命与耐环境能力,请确认器件的温度循环、湿热与冲击试验数据。

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.
