PANJIT(强茂)作为全球功率半导体领域的资深制造商,深耕电子元器件研发生产数十年,其MMSZ5236B_R1_00001属于表面贴装独立式稳压二极管,针对小体积、中低功耗稳压场景优化,广泛适配消费电子、工业控制、车载电子等领域的辅助稳压与过压保护需求。该器件以稳定的电气特性、紧凑的封装设计,成为低成本稳压方案的优选之一。
标称稳压值为7.5V,实际工作范围覆盖7.13V~7.88V(对应公差±5%),符合工业级稳压管的常见精度要求。该范围可满足大多数对稳压精度要求不苛刻的场景(如普通电源模块输出稳压、传感器参考电压等),避免因电压波动导致的电路异常。
在反向电压6V(低于标称稳压值)时,反向漏电流仅3μA,远低于同类产品≤10μA的典型水平。低漏电流意味着静态功耗极低,适合对功耗敏感的便携式设备(如无线耳机充电盒、智能手环辅助电路),可延长电池续航时间。
最大耗散功率为500mW,匹配SOD-123封装的热容量,可稳定承受持续或脉冲式功率负载(如电源过压时的瞬间能量耗散),避免过热导致的性能衰减或器件损坏。
该器件采用SOD-123表面贴装封装,尺寸紧凑(典型值:长2.9mm×宽1.6mm×高1.1mm),引脚间距1.27mm,适配高密度PCB设计,可有效节省电路板空间,适合小型化电子设备(如智能穿戴、车载小模块)。
封装符合RoHS无铅无卤标准,兼容回流焊、波峰焊等主流焊接工艺,生产效率高;同时具备良好的机械强度,可承受常规振动与冲击(如车载环境的颠簸)。
如智能手机充电器、无线耳机充电盒的辅助稳压电路,为内部电路提供稳定的7.5V供电,避免电网电压波动影响设备性能;也可用于小型蓝牙音箱的电源滤波稳压。
PLC(可编程逻辑控制器)的I/O端口、传感器接口的过压保护:当外部电压异常升高时,稳压管快速击穿,钳位电压至7.5V左右,保护敏感电子元件(如光耦、运算放大器)不受损坏。
温度传感器、压力传感器的供电或参考电压源:利用其低漏电流、稳定的稳压特性,保证传感器输出信号的准确性(如工业温度监测系统的传感器供电)。
车载多媒体系统的辅助稳压电路:覆盖-55℃~+150℃的宽温范围,适应车载环境的极端温度变化,为车机屏幕、音频模块提供稳定电压。
若需替换该器件,需匹配核心参数:稳压值范围7.13V~7.88V、封装SOD-123、耗散功率500mW、反向漏电流≤3μA@6V。
综上,PANJIT MMSZ5236B_R1_00001以高性价比、稳定的电气特性和紧凑封装,成为小功率稳压与过压保护场景的实用选择,适配多领域电子设备的需求。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
