BZV55B3V3 产品概述
一、概述
BZV55B3V3 是一款独立式稳压二极管，标称稳压值 3.3V（规定范围 3.23V–3.37V），由 LGE(鲁光) 提供，常见封装为 LL-34 / SOD-80。器件适用于小功率定点稳压和参考电路，具有低反向漏电和较宽的工作结温范围（-65℃ 至 +200℃）。
二、主要特性
- 稳压值（标称）：3.3V；允许范围：3.23V ~ 3.37V
- 反向电流：Ir = 2μA @ 1.0V（应按实际应用的反向电压和温度重新确认）
- 最大耗散功率：Pd = 500mW（散热受封装和 PCB 条件影响）
- 阻抗：Zzt = 85Ω（在测试工作点下的动态阻抗）；Zzk = 600Ω（击穿区低电流时的阻抗或膝点阻抗）
- 工作结温：-65℃ ~ +200℃
- 封装：LL-34 / SOD-80，适合分立元件布板
三、电气参数要点说明
稳压二极管的稳压值随电流和环境温度变化，给出的 3.23–3.37V 是在指定测试电流下的典型范围。Zzt（动态阻抗）反映在工作电流附近电压随电流变化的敏感度，值越小稳压性能越好；Zzk 指示在接近击穿区低电流时的阻抗特性，对低电流参考源设计有参考价值。Pd 为器件在良好散热条件下的最大耗散功率，实际电流应保证在 Pd 限值和器件温升许可范围内运行，必要时采用热沉或改善 PCB 散热。
四、典型应用
- 精密基准电压源与稳压点（低功耗电路）
- 参考电路、ADC/DAC 的基准或基线校正
- 过压保护与限压电路（需配合串联电阻）
- 便携式与电池供电设备中的局部稳压
五、封装与安装建议
LL-34 / SOD-80 为小型封装，应保证焊点热容量足以散热并避免过热。布板时缩短热阻路径、增大焊盘面积并靠近散热层放置，可提高可用功率。焊接推荐遵循元器件焊接温度曲线，避免长时间高温暴露影响结温极限。
六、选型与使用注意
在设计前请参照完整规格书确认测试电流点（Izt/Izk）、温度系数、稳压与阻抗的具体测试条件。实际电路中常在稳压二极管前串联限流电阻以控制工作电流，防止瞬态和过流损坏。对于对噪声和温漂敏感的参考应用，建议进行实际温度与负载扫描以验证稳定性与误差范围。

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.
