MMSZ5236B（CJ）产品概述
一、产品简介
MMSZ5236B 是江苏长电（CJ）出品的一款独立式稳压二极管（齐纳二极管），标称稳压值 7.5V，封装为 SOD‑123。器件为小信号封装的低功耗稳压元件，适用于空间受限和低功耗的电压基准与过压保护场合。
二、电气参数（关键）
- 标称稳压值：7.5V
- 实测稳压范围：7.13V ～ 7.88V
- 反向漏电流（Ir）：3 µA（说明：给出为 3µA@6V 条件）
- 耗散功率 Pd（最大）：350 mW
- 动态阻抗 Zzt：6 Ω（工作/测试条件下）
- 动态阻抗 Zzk：500 Ω（低电流区）
- 工作结温范围：-65 ℃ ～ +150 ℃
- 封装：SOD‑123
三、主要特性
- 小封装、体积小，适合贴片组装与高密度电路板应用。
- 稳压值集中，7.13V～7.88V 的范围适合需要 7.5V 基准或限压的低功耗电路。
- 低反向漏流，在中低电压下漏电小，有利于电路的静态功耗控制。
- 低至中等动态阻抗（Zzt≈6Ω），在设计合适偏置电流时可获得较稳定的稳压特性。
四、典型应用
- 小电流电压基准与偏置源（传感器、模拟前端）。
- 过压/浪涌钳位与取样保护。
- 便携式设备与低功耗模块中的辅助稳压。
- 分立式基准替代与电路调试。
五、设计与使用建议
- 功率与散热：最大耗散功率为 350 mW，设计时必须保证在最大结温下器件不会超过 Pd；若环境温度升高需适当降额使用或采用外部散热/降低偏置电流。
- 串联限流电阻：常采用串联电阻 R = (Vin − Vz)/Iz 计算，使稳压电流 Iz 保持在器件的安全工作范围内；同时检查 R 上的功耗及器件耗散是否满足要求。
- 工作电流选择：推荐在数百微安至几毫安范围内工作以兼顾稳压精度与功耗（具体可根据系统精度需求与测试数据调整）。
- 启动与稳定：在快速变化输入下，必要时在稳压二极管与地之间并联小电容以抑制瞬态振铃，但需注意影响动态响应。
六、质量与选型提示
- 选择时注意封装与焊接工艺兼容性（SOD‑123 适合常规回流焊）。
- 对温漂、长期稳定性有严格要求的应用，应结合实际样品测试验证稳压范围与温度系数。
- 若需要更高功率或更严稳压精度，可选用更大封装或专用低噪声电压基准芯片。
如需具体测试曲线、温度特性或在特定偏置条件下的稳压曲线，可提供更详细的器件数据手册或样片测试结果以便准确选型与电路验证。

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.
