SM5100A 是LRC(乐山无线电)出品的一款独立式肖特基整流二极管,封装为SMA(DO-214AC)。器件额定反向耐压为100V,额定整流电流5A,非重复峰值浪涌电流(Ifsm)100A,工作结温范围为-40℃~+150℃。在典型工作点5A时正向压降约为0.85V(Vf@5A=850mV),适用于开关电源整流、输入保护与高频功率整流等场景。
总结:SM5100A 在100V/5A 级别下以肖特基低正向压降与良好的浪涌承受能力为主要优势,适合中低压高频整流与防护应用。但由于SMA封装的散热限制,在接近额定连续电流使用时必须做好PCB热设计与热降额评估,以保证长期稳定可靠运行。

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.
