LMBR140ET1G 是东沃(DOWO)推出的一款肖特基势垒整流二极管,单只独立器件,额定直流整流电流 1A,最大反向电压 40V,采用超小型SOD-323HE封装。肖特基结结构保证了较低的正向压降和快速恢复特性,适合空间受限、需降低导通损耗的整流与保护场合。
SOD-323HE 是一种极小型表贴封装,适用于高密度贴片电路板。该封装体积小、引脚距短,便于自动贴装与回流焊接但热容有限,因此在高电流或持续功耗情况下需注意散热设计与封装限制。元件外形上通常有极性标识,贴装时注意方向与丝印对应。
总结:LMBR140ET1G 在小尺寸、低正向压降与快速整流场合具有明显优势,适合便携设备与空间受限的电源应用,但在热管理与漏电敏感场景需谨慎评估并合理布局散热与保护措施。如需详细热阻、极限参数曲线与封装尺寸,请参考原厂数据手册。

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.
