LDSR01S30ST5G 是乐山无线电(LRC)推出的一款肖特基二极管,采用 DFN0603 小封装,面向便携式和高密度电路板的低压整流与防反接应用。器件以低正向压降和低反向漏电为主要卖点,适合在空间受限且需降低导通损耗的场景使用。
DFN0603 封装导热面积有限,建议在 PCB 设计时优化焊盘和散热过孔布局以提升热耗散能力。采用常规无铅回流焊工艺,注意控制回流曲线以避免过热引起性能退化。采用良好焊盘定义(solder mask defined / paste stencil)可提高coplanarity和焊接一致性。
LDSR01S30ST5G 在追求小体积、低损耗和低待机电流的低压电源设计中具有很好的性价比,是便携与嵌入式电源保护与整流的常用选择。

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.
