BZX584C6V8 Z5（CJ 长晶）产品概述
一、概述
BZX584C6V8（Z5等级）为CJ（江苏长电/长晶）生产的独立式稳压二极管，标称稳压值6.8V，实际出厂范围6.4V～7.2V。器件采用SOD-523超小型贴片封装，面向低功耗、小体积的电压基准与防护应用。典型反向漏电流Ir≤100nA，最大耗散功率Pd=150mW，适合便携与空间受限场合。
二、电气特性要点
- 稳压值（标称）: 6.8V；稳压范围: 6.4V–7.2V。
- 反向电流Ir: 100nA（典型条件下为小电流泄漏指标）。
- 耗散功率Pd: 150mW，需考虑封装散热与PCB面积。
- 动态阻抗: Zzt≈15Ω（工作区态阻抗），Zzk≈80Ω（接近击穿或低电流区阻抗）。
这些参数表征了器件在不同偏流下的稳压稳定性与噪声性能，动态阻抗越小，稳压随电流变化越稳定。
三、典型应用场景
- 低功耗电压基准与微小电源稳压（如传感器、电表、便携终端）。
- 电路偏置与参考源，用于比较器或ADC前端的小信号参考。
- 输入浪涌或反向保护的简单钳位元件（非替代高能瞬态抑制器）。
SOD-523的体积优势适合高密度PCB设计，但在热耗散与峰值电流上需谨慎。
四、典型电路与设计注意
在做稳压基准时常见方案为：Vin串联限流电阻R，与二极管并联于负载。电阻取值按R=(Vin−Vz)/(Iz+IL)估算，其中Iz为二极管工作电流，IL为负载电流。鉴于Pd仅150mW，应保持二极管上消耗功率低于额定，避免在高Vin与大限流电阻组合下长期高功耗工作。为提高温漂与稳定性，可在合适Iz下运行，避开极低电流区（Zzk影响较大）与过流区。
五、封装与可靠性建议
SOD-523为超小型表贴，焊接时推荐回流工艺并严格控制温度曲线；取放需使用真空点胶或贴装机。贴片尺寸小，焊盘热散能力有限，建议在PCB上增加散热铜箔或散热通孔以提升功耗承载。存储运输注意防潮与静电防护（ESD），并参考制造商的焊接与回流规范。
六、选型要点与替代方案
选择时关注稳压公差（6.4–7.2V是否满足系统容差）、最大耗散功率与工作环境温度。若系统需更低噪声、更高功率或更好温漂，可考虑更高Pd或采用小型LDO参考/稳压芯片；若仅为瞬态钳位，应评估TVS器件以替代。
总结：BZX584C6V8 Z5适合对体积、功耗有严格要求的低功耗稳压与基准场合，使用时需注意功率限制与合理的偏置电流，以保证长期稳定与可靠。

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.
