该器件为台湾强茂(PANJIT)半导体推出的表面贴装稳压二极管,型号为1SMB3EZ16_R1_00001,属于1SMB系列小功率稳压管范畴。核心功能是通过反向击穿特性实现16V(标称值)稳定电压输出,适配SMB标准封装,最大耗散功率3W,是工业控制、通信设备、消费电子等领域常用的稳压/过压保护元件。
标称稳压值16V,实际工作范围覆盖15.2V~16.8V(误差±5%),兼顾生产工艺偏差与温度变化影响,满足中精度稳压场景需求。若需更高精度,可通过温度补偿优化。
反向电压12.2V(远低于稳压值)时,漏电流仅500nA(纳安级),属于低功耗设计——可有效降低待机损耗,适配便携式设备、低功耗系统(如智能传感器)。
工作结温覆盖**-55℃+150℃**,超出工业级(-40℃+125℃)要求,可稳定工作于极端环境(如户外通信设备、汽车发动机舱)。
采用SMB(DO-214AA)表面贴装封装,具备三大核心优势:
并联于直流电源输出端,配合限流电阻实现16V稳定输出,适配单片机、传感器等模块供电(如12V升压、24V降压场景)。
电压尖峰(雷击、开关浪涌)时反向击穿,钳位电压至16V左右,保护后级敏感元件(如通信芯片、存储器件)。
低动态阻抗+宽温特性,可为ADC/DAC等模拟电路提供16V参考电压,无需额外精密基准芯片。
宽温能力适配工业控制柜、汽车仪表盘/传感器模块,满足极端环境可靠性要求。
机顶盒、路由器、智能家居设备的电源模块,用于稳定辅助电源电压,提升设备稳定性。
PANJIT(强茂)作为全球半导体厂商,该系列产品通过AEC-Q101(汽车级)、ISO9001认证,具备批量一致性与长期可靠性,可满足工业级、汽车级应用需求。
该器件凭借“宽温、低漏、高稳压精度”的特点,成为中小功率稳压/保护场景的高性价比选择。

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.
