MMSZ5225B_R1_00001是台湾强茂电子(PANJIT)推出的独立式稳压二极管,属于小功率表面贴装器件。该型号以3V为标称稳压值,适配对电压稳定性要求中等、空间受限的电子电路设计,是消费电子、工业控制、物联网终端等领域的常用基础元件。
标称稳压值3V,稳压范围2.85V~3.15V(偏差±5%),可覆盖多数轻负载电路的电压稳定需求,无需额外校准即可满足一般精度要求。
Ir=50uA(@1V反向电压),漏电流极小,静态功耗低,尤其适合电池供电设备(如智能手环、蓝牙耳机),可延长电池续航时间。
最大耗散功率Pd=500mW,结合稳压值计算,最大允许负载电流约166mA(I=Pd/Vz),满足轻至中等负载场景(如传感器、低功耗MCU供电)。
工作结温范围**-55℃~+150℃**,覆盖工业级温度标准,可在极端环境(如户外传感器、车载辅助电路)下稳定工作。
采用SOD-123表面贴装封装,典型尺寸为2.3mm×1.2mm×1.0mm,体积小巧,适合高密度PCB布局(如智能手表、小型物联网模块)。封装为塑封结构,具备以下优势:
智能手环、蓝牙耳机、TWS耳机的辅助电源模块,提供稳定3V参考电压,满足低功耗MCU、加速度传感器的供电需求。
工业温度/压力传感器的模拟前端,3V稳压可提升ADC采样精度,减少环境温度变化对测量结果的影响。
微控制器(MCU)、通信接口(UART、I2C)的反向过压钳位,防止静电(ESD)或瞬态电压(如电源波动)损坏芯片。
纽扣电池供电的小型设备(如电子标签、遥控器),低漏电流特性可延长电池寿命,稳定输出电压保障电路正常工作。
强茂电子(PANJIT)是全球知名分立半导体厂商,产品符合RoHS 2.0、REACH等环保标准,批量生产一致性好(稳压范围控制严格),广泛应用于汽车电子、工业控制、消费电子领域,品质可靠性经市场长期验证。
该型号凭借“小体积、低功耗、宽温范围”的核心优势,成为轻负载稳压场景的高性价比选择。

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.
