BAV21WS(品牌:YANGJIE/扬杰)是一款独立式高压快速开关二极管,封装为SOD-323,适用于空间受限的表面贴装电路。该器件在200mA工作电流下正向压降仅约1.25V,反向耐压高达250V,兼顾高压耐受能力与快速开关性能,适合小信号与功率受限的开关与整流应用。
这些参数表明,BAV21WS在高压、低漏电流及中等开关速度场合表现优良,特别适合对漏电流敏感或需要较高反压的应用。
在200mA正向工作时,器件功耗约为0.25W(P = I·V = 0.2A·1.25V),已接近Pd标称值250mW;因此在持续工作条件下需重视散热与电流裕度。SOD-323为小型封装,建议在PCB设计时优化铜箔散热与焊盘热通道,避免长期在高环境温度下满载工作。遵循厂商回流焊曲线(峰值温度 ≤ 260℃)进行贴片焊接,存储与操作时防潮防静电,按厂家说明处理。
SOD-323封装适合高密度SMT组装,适用于自动贴片生产线。订购时请确认完整型号(BAV21WS)、品牌(YANGJIE/扬杰)、以及包装形式(卷带/盘带)以满足生产需求。需要更详细的封装尺寸、电气特性曲线及回流焊参数,请参照厂商数据手册或向供应商索取样片与测评数据。
总结:BAV21WS为一款兼具高压耐受、低泄漏与快速开关特性的SOD-323封装二极管,适合空间受限且需高压小电流整流或快速开关的电子设计。

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.
