BAT43WS 是一款基于肖特基势垒结构的低压降小信号二极管,由 GOODWORK(固得沃克)生产,封装为 SOD-323、小巧独立式元件。该器件具有极低的正向压降和良好的开关速度,适用于便携设备、功耗敏感电路及高频检测/整流场合。额定反向耐压为 30V,最大整流电流 200mA,适合小电流整流与保护用途。
SOD-323 小型封装适合空间受限的电路板设计。该封装体积小、焊接良好,但热阻相对较高,需在设计中注意散热路径和铜箔面积的合理布局,以避免长期大电流下的结温升高。
BAT43WS 的工作结温范围宽,适用于工业环境。长期可靠性受工作温度、反复热循环和过流事件影响,建议在产品验证阶段进行加速寿命测试(温度循环、湿热、振动)以确认在目标应用中的稳定性。
若目标应用要求更高电流或更高反向耐压,可考虑功率更大的肖特基或整流二极管;若需要更低漏电或更低 Vf,应在参数表中比较温度特性与试样数据。GOODWORK(固得沃克)提供一致性良好的批次供应,适合量产应用。
总结:BAT43WS 是一款小型、低压降、适合低功耗与高频信号场合的肖特基二极管,凭借 30V 的耐压与 200mA 的连续电流能力,在便携设备、电平整流与保护电路中具有良好性价比。选用时应综合考量工作电流、热管理与漏电在高温下的变化。

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.
