LRB551BS-30T5G是乐山无线电(LRC)推出的低正向压降、中低压肖特基二极管,采用独立式双引脚设计,适配表面贴装工艺,主要面向消费电子、小型电源及低功率电路的整流、续流等场景,以高效能、高可靠性为核心优势。
该器件属于小功率肖特基二极管,聚焦“低导通损耗+中低压应用”场景:反向耐压覆盖30V直流电压,持续整流电流达500mA,正向压降仅540mV(@500mA典型电流),在同类中低压肖特基中表现出优异的效率优势,适合对功耗敏感的紧凑型电路设计。
正向压降(Vf)是肖特基二极管的核心性能指标,LRB551BS-30T5G在500mA持续电流下仅540mV,相比部分同耐压等级产品(如部分1N5817系列)压降更低,可显著降低导通损耗,提升电路效率。例如在5V电源输出电路中,该器件的功率损耗比高VF产品减少约15%~20%。
工作结温范围为**-65℃~+150℃**,覆盖工业级温度要求,可在极端环境(如户外设备、汽车辅助电路)中稳定工作,无需额外降额设计。
LRB551BS-30T5G采用SOD-882表面贴装封装,属于小型双引脚封装(典型尺寸约1.6mm×0.8mm×0.6mm),具备以下优势:
结合参数特性,该器件主要应用于以下场景:
综上,LRB551BS-30T5G肖特基二极管以“低VF、小体积、宽温适配”为核心,精准匹配中低压小功率电路的整流、续流需求,是消费电子、汽车电子及工业控制领域的高性价比选择。

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.
