BAV21WT 是创基(CBI)提供的一款高反向耐压、小型封装的独立式二极管,采用 SOD-523 封装,适合高密度表面贴装电路。该器件定位为小信号整流/开关用途,兼顾高反向电压和低泄漏电流的要求,适用于空间受限且需承受较高反向电压的应用场合。
以上参数为关键设计依据,选型时应同时参考具体应用的工作条件与热环境。
SOD-523 为超小型SMD封装,适合高密度贴片设计。该封装体积小、引线长度短,有利于降低寄生电感,但同时限制了散热能力与可承载电流。机械强度适合自动贴片与回流焊工艺,但手工焊接需注意焊接热量控制以免损伤器件。
总结:BAV21WT 以其 200 V 的高反压、极低的反向电流和超小型封装特点,适合空间受限且需高压耐受的小信号整流或保护应用。选用时应重点考虑功率耗散与散热布局,合理降额以保证长期可靠性。

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.
