BZX584C3V0 产品概述（CJ 长晶，SOD-523）
一、产品简介
BZX584C3V0 是一款小功率独立式稳压二极管（Zener），由 CJ（江苏长电/长晶）生产，封装为表面贴装 SOD-523。标称稳压值为 3.0V，允差区间为 2.8V～3.2V，适用于对体积和成本敏感的便携设备、信号接口和参考电路等场合。
二、主要电气特性
- 稳压（标称）：3.0V
- 稳压范围：2.8V ～ 3.2V
- 反向漏电流 Ir：50µA @ 1V（指在 1V 反向偏压下的漏电）
- 动态阻抗 Zzt：100Ω（用于评估稳压时随电流变化的电压波动）
- 器件类型：独立式（分立元件），小功率稳压/箝位器件
（以上参数为关键参考值，实际选型时请以完整器件规格书为准，注意测试电流和温度条件会影响稳压值与阻抗。）
三、典型应用
- 低电压参考与基准电路
- 电源浪涌/过压保护（对敏感信号线进行钳位）
- MCU/ADC 输入的电平保护与基准源
- 移动设备、可穿戴设备、传感器节点等对空间要求高的电路
四、封装与安装
SOD-523 封装体积非常小，适合高密度 PCB 布局和自动贴装。因体积小，热阻相对较高，长期散热能力有限；在布局时应考虑与散热相关的设计（如邻近大铜箔或散热通路）。
五、使用建议与注意事项
- 稳压器应与限流电阻串联工作以控制流过二极管的电流；避免在超过器件允许的功耗下长时间工作。
- 由于 3V 附近的稳压通常以 Zener 机理为主，器件有明显温度系数（随温度变化会导致稳压点漂移），在精密参考场合需加温度补偿或采用更精确的参考源。
- 动态阻抗较高时（Zzt = 100Ω），稳压精度受电流变化影响明显，建议在设计中保证工作电流稳定或采用滤波电容降低噪声。
- 漏电流会随温度上升而增加，低电流应用（µA 级）需关注温漂与漏电带来的偏差。
- 注意 ESD 与焊接工艺，避免因过热或静电损坏器件。
六、典型电路示例与计算提示
一个常见的并联稳压（分流）电路：在电源 Vs 与负载/地之间并联 BZX584C3V0，并在输入端串接限流电阻 R。若期望在约 1mA 工作电流下稳压（示例），Vs = 5V，则 R ≈ (5V − 3V) / 1mA = 2kΩ；同时需核算二极管与电阻的功耗，确保不超过器件允许范围并留有裕量。
七、采购与品质
选购时确认完整料号 BZX584C3V0 及 CJ（长晶）品牌，注意封装 SOD-523 对应的带卷或散装形式，查看批次、检验报告与规格书，以保证稳压精度与可靠性满足设计要求。
如需更精确的电气特性曲线、最大允许功耗、温度系数和测试条件，请提供或查阅 CJ 官方规格书，以便进行精确设计与热管理评估。

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.
