BAV21WS 是晶导微电子推出的一款独立式开关/整流二极管,采用 SOD-323 小型封装,面向体积受限且要求高速开关与高压耐受的电路应用。该器件具有较低的正向压降、较高的反向耐压以及极小的反向电流,适合在便携设备、消费电子及工业控制中做为信号整流、开关切换与保护元件使用。
SOD-323 小型封装便于在有限空间内实现高密度布局。由于体积小,散热能力受限,建议在 PCB 设计时为焊盘提供合理的铜箔面积和热通道,避免器件在连续高电流或高频工作时温度累积超过规格范围。
型号:BAV21WS
品牌:晶导微电子
封装:SOD-323
该型号适合需要在小体积条件下实现 250 V 耐压、低漏电和快速开关的设计方案。购买时请确认器件外观、标识及完整规格书,以便与系统设计参数一致。

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.
