1SMAF4745A 是晶导微电子推出的一款独立式稳压二极管(稳压管),采用 SMAF 封装,面向中低功率的稳压与过压保护应用。该器件名义稳压值为 16V,实际出厂稳压范围为 15.2V ~ 17.1V,工作结温范围宽(-55℃~+150℃),适合在较为严苛的温度环境中长期工作。器件在反向工作区表现为较稳定的电压特性与适合电路设计的阻抗特性,适合用于基准源、局部稳压、浪涌/过压钳位以及电源保护等场景。
1SMAF4745A 为一款面向中低功率稳压与保护的独立式稳压二极管,具有 16V 的名义稳压、较低的漏电和中等动态阻抗,适用于需要节约 PCB 面积且对精度要求不是极端严格的工业与消费电子场合。设计时应重视散热与工作电流的限制,并在对稳压精度有更高要求的场合考虑配合温度补偿或采用更低阻抗的替代方案。
如需更详细的电气特性曲线、典型测试电流条件与热阻数据,请参照晶导微电子的完整产品数据手册或联系厂家技术支持。

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.
