BZT52C3V9是富芯森美(FUXINSEMI)推出的独立式稳压二极管,采用SOD-123小型表面贴装封装,核心功能是提供稳定的3.9V参考电压,兼具低功耗、宽温适应性等特点,适用于多类电子设备的电压稳压场景,可有效简化电路设计、降低成本。
该型号的关键参数直接决定了其应用适配性,具体解析如下:
标称稳压值为3.9V,实际工作范围覆盖3.7V~4.1V(偏差±5%),电压一致性良好,无需额外复杂的电压调整电路即可满足多数电路对稳压精度的基础需求,尤其适合对稳压范围要求不苛刻的中小功率场景。
反向漏电流(Ir)仅为3uA(测试条件:反向电压1.0V),漏电流处于极低水平,静态功耗可忽略不计——这一特性使其成为电池供电设备(如智能穿戴、无线耳机)的理想选择,能有效延长设备续航时间,减少电源损耗。
工作结温覆盖**-55℃+150℃**,远超普通稳压二极管的温度上限(通常为-40℃+125℃),可适应极端环境(如工业车间、户外监测设备),在高低温交替场景下仍能保持性能稳定,降低设备故障风险。
结合参数特性,BZT52C3V9的适配场景涵盖以下领域:
采用SOD-123小型表面贴装封装,尺寸紧凑(典型尺寸约2.0mm×1.25mm),适合高密度PCB布局,可有效节省电路板空间;引脚设计合理,焊接兼容性强,支持自动贴装(SMT)工艺,提升生产效率。
富芯森美(FUXINSEMI)作为专业半导体器件供应商,对BZT52C3V9实施严格质量管控:
总结而言,BZT52C3V9稳压二极管凭借精准稳压、低功耗、宽温适应性及紧凑封装等优势,成为消费电子、工业控制、通信等领域的实用稳压方案,可有效提升电路供电稳定性,降低设计成本。

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.
