MMSZ5246B（YANGJIE 扬杰）16V 稳压二极管 产品概述
一、产品概述
MMSZ5246B 是一款标称稳压值为 16V 的小功率稳压二极管，采用 SOD-123 封装，由 YANGJIE（扬杰）生产。该器件在反向工作时作为稳压元件提供稳定的电压参考或浪涌钳位，适用于空间受限且要求低漏电的小电源与参考电路中。
二、主要电气参数
- 稳压值（标称）：16V
- 稳压值范围：15.2V ~ 16.8V
- 反向电流 Ir：100 nA（@ 12V）
- 最大耗散功率 Pd：500 mW（环境与散热条件决定实际允许功率）
- 阻抗 Zzt：17 Ω
- 阻抗 Zzk：600 Ω
- 工作结温范围：-55 ℃ ~ +150 ℃
这些参数决定了器件在不同电流和温度下的稳压精度、噪声和动态响应特性。
三、特点与优势
- 低漏电：在 12V 时反向电流仅 100 nA，有利于低功耗与高阻态电路。
- 中等稳压精度：15.2–16.8V 的公差适合一般参考与保护用途。
- 小型封装：SOD-123 体积小、便于表贴组装，适合紧凑设计。
- 可靠的温度范围：-55℃ 至 +150℃，可在苛刻环境下工作。
- 合理的动态阻抗：Zzt 17 Ω 提供较好的稳压能力，Zzk 表征在不同工作区的响应。
四、典型应用
- 小电流基准电压源与偏置电路
- 过压或浪涌保护、输入钳位
- 便携设备与仪表的参考稳压
- 晶体管/运放偏置与保护电路中的电压钳位
五、使用与布局建议
- 避免超过 500 mW 的耗散；在高环境温度下需降额使用或通过良好铜箔散热来提高功率承受能力。
- 稳压二极管通常在反向偏置工作，需配合合适的串联限流电阻以控制流过电流，防止过功耗。
- SOD-123 封装热阻较大，印制板上增加散热铜箔、缩短引线长度并远离热源可改善热性能。
- 对于对稳压噪声与精度有更高要求的应用，建议配合滤波电容并在实际温度范围内测试电压漂移。
六、封装与采购
- 品牌：YANGJIE（扬杰）
- 封装：SOD-123（表面贴装）
- 型号示例：MMSZ5246B（16V，500mW）

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
