MM3Z15VC是安森美(ON Semiconductor) 推出的一款表面贴装稳压二极管,属于MM3Z系列独立式稳压管,核心功能为提供15V稳定电压输出,适配小型化、低功耗电子电路的稳压需求。安森美作为全球知名半导体厂商,其器件以高可靠性、一致性著称,MM3Z15VC继承了品牌的工艺优势,适合消费电子、可穿戴设备等领域的量产应用。
MM3Z15VC的核心参数围绕稳压精度、功耗、漏电流等关键指标设计,具体如下:
MM3Z15VC采用SOD-323F 表面贴装封装,属于超小型封装类型,尺寸约为1.6mm×0.8mm×0.6mm(典型值),具有以下优势:
基于低功耗、小尺寸、15V稳压的核心特性,MM3Z15VC广泛应用于以下场景:
如智能手环、蓝牙耳机、智能手表等电池供电设备,需15V辅助电压(如某些传感器、无线模块的工作电压),低漏电流可延长电池续航,小尺寸适配设备微型化设计。
在简单模拟电路中,可作为低成本电压基准(替代复杂的基准芯片),用于运放偏置电压、ADC参考电压等场景,满足小电流、中等精度的需求。
在电路输入端或关键节点,反向并联MM3Z15VC,当电压超过15V时器件击穿导通,将电压钳位在15V左右,保护后端敏感元件(如MCU、传感器)免受过压损坏。
小型工业控制器、传感器模块的辅助电源稳压,安森美的高可靠性可满足工业级环境的稳定性要求。
为确保器件长期可靠工作,需注意以下要点:
若需替代MM3Z15VC,可优先选择同品牌同系列的MM3Z15V(参数一致),或其他品牌同规格器件(如NXP的BZX84C15V、东芝的1SMA15CA等),但需注意封装一致性,避免影响电路设计。
总结:MM3Z15VC凭借小尺寸、低功耗、高可靠性的特点,成为15V稳压场景的优选器件,尤其适合便携式设备和小型化电路的量产应用。
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.
