BZX584C13 产品概述
一、基本特性
BZX584C13 是 CJ（江苏长电/长晶）生产的一款独立式稳压二极管，标称稳压值 13V，生产批次允许的稳压范围为 12.4V～14.1V。器件采用超小型 SOD-523 封装，适合体积受限、轻载电源稳压与基准应用。工作结温范围宽：-55℃～+150℃，适用于一般工业级温度环境。
二、主要电气参数
- 标称稳压：13V（有效范围 12.4V～14.1V）
- 反向电流 Ir：100nA @ 10V（漏电流极小，适合对偏置泄漏敏感的电路）
- 阻抗：Zzk = 170Ω（低电流区阻抗），Zzt = 30Ω（测试电流下的动态阻抗）
- 最大耗散功率 Pd：150mW（器件在良好散热条件下的极限功耗）
- 封装：SOD-523（超小表贴）
以上参数表明该型号在低电流、小功率场景下具有较好的稳压和低泄漏特性，但由于封装和Pd限制，不适宜大电流恒流稳压场合。
三、典型应用场景
- 作为低功耗电路的参考电压源与基准点（模数转换参考、比较器参考）
- 小信号电路的限幅、箝位与电平移位
- 精密偏置、偏流源的稳压元件（低电流工作）
- 容量受限或轻载的便携设备与传感器节点电源保护
四、热与功耗注意事项
器件额定耗散功率为 150mW，但 SOD-523 为微型封装，实际电路板上的热阻较大，推荐在实际应用中进行保守设计与热/功耗计算。计算示例：若工作在 Iz = 5mA，二极管功耗 P = Vz × Iz ≈ 13V × 5mA = 65mW，处于安全范围；若 Iz 接近 11.5mA 则接近 150mW 极限，不建议长期运行。建议常态工作电流控制在 1–5mA 区间，以保证稳定性与可靠性。
五、封装与安装建议
SOD-523 为极小尺寸封装，焊接时注意回流温度曲线控制，避免过热；焊盘布线应尽量短，减小寄生电感与热阻。若需稍改善散热，可在焊盘周围增加铜箔面积，但受空间限制时效果有限。为减少干扰和漏泄误差，建议靠近被驱动电路布置并加短地线。
六、选型与电路使用建议
- 作为稳压使用时需串联限流电阻 Rs，计算公式 Rs = (Vin - Vz) / Iz（选择 Iz 在安全范围内）。例如 Vin = 20V，目标 Iz = 5mA，则 Rs = (20-13)/0.005 = 1.4kΩ，二极管耗散 ≈65mW。
- 考虑温漂与稳压范围，需在系统容忍的偏差内使用；对精度要求高的场合建议配合后端误差修正或采用精密基准源。
- 对于极低电流或超小封装热限制的应用，推荐优先评估稳压器或带参考输出的集成解决方案。
总结：BZX584C13 适合体积受限、低功耗场合的 13V 稳压与电平保护应用，具有低漏电和较高的工作温度范围。使用时重点关注最大耗散功率与封装热限制，通过合适的串联限流与布线设计可获得稳定、可靠的性能。

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.
