SMA4733A 是扬杰(YANGJIE)推出的一款单体稳压二极管,采用SMA (DO-214AC) 低外形封装,标准稳压值为5.1V(标称)。该器件为玻璃钝化芯片结结构,具有高正向浪涌能力和优秀的焊接可靠性,适用于自动贴装的表面贴装工艺(SMT)。符合J-STD-020的MSL 1级,最高峰值回流温度可达260℃,便于工业化量产与可靠装配。
这些参数表明 SMA4733A 在小功率稳压场合具有较低的动态阻抗和可预测的电压特性,适合用于需要一定稳定性的精密偏置或参考电压场合。
SMA封装在占板面积与散热能力之间取得平衡,适合空间受限而又需一定功耗处理的应用。
SMA4733A(YANGJIE)是一款面向小功耗稳压与保护应用的高可靠SMA封装稳压二极管,具有稳定的5.1V标称电压、低稳态阻抗(Zzt=7Ω)和良好的工艺兼容性(MSL1,260℃回流峰值)。其玻璃钝化工艺与高正向浪涌能力,使其在工业、通信及消费电子的局部稳压与保护电路中具备较高的适用性与可靠性。若需进一步选型建议或电路匹配计算,可提供具体工作电流与温度条件以获得更精确的应用指导。

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.
