SMD36PL-TP 是美微科(MCC)出品的一款 3A Schottky 整流二极管,采用低剖面 SOD-123FL 表面贴装封装。器件适用于中低功率开关电源、整流和反向保护等场合,凭借 Schottky 二极管本身的低正向压降与快速开关特性,可在提高效率与降低发热方面提供明显优势。
该器件在额定工作点(3A)下的正向压降约为0.65V,适合用于要求低压降以降低功耗与发热的整流场合。60V 的反向耐压使其能胜任典型的24V及更低电压系统保护与整流任务。反向漏电流在最大 Vr 条件下为 100µA,适合多数功率与保护应用的漏电限值要求。
SOD-123FL 封装具有体积小、可焊接面积适中的优点,但热阻相对较高。为保证长期可靠运行,应在 PCB 设计时为二极管引脚附近预留适量铜箔并考虑增加热沉铜区域或过孔以辅助散热。在高电流或高环境温升的工作条件下,应遵循器件的电流-温度降额规则,避免长期在接近最大结温下工作。
器件工作结温范围宽(-55℃ ~ +150℃),适合工业级应用。长期可靠性取决于正确的热管理与避免超出最大反向电压或持续超额电流。对湿敏度、焊接兼容性等具体可靠性试验项请参阅美微科正式数据手册。
在选型时应依据系统工作电压、最大工作电流、允许的正向压降及散热条件来确认 SMD36PL-TP 是否满足需求。对于需要更高耐压或更低漏电的应用,可考虑更高 Vr 或更低 Ir 的型号;若系统对导通损耗要求更苛刻,可优先选择 Vf 更低的 Schottky 器件。订购或批量应用前,建议索取并核对美微科最新 datasheet 与封装图纸,确认回流工艺与可靠性测试数据。

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.
