BZT52-B30_R1_00001 产品概述
一、产品简介
BZT52-B30_R1_00001 为 PANJIT（强茂）出品的小功率稳压二极管，封装为 SOD-123，属于独立式稳压二极管系列。标称稳压值为 30V，公差范围 29.4V～30.6V（约 ±2%），适用于对中高电压点的稳压、基准与钳位场合。
二、关键电气参数
- 稳压值（标称）：30V（范围 29.4V～30.6V）
- 反向电流 Ir：100nA @ 22.5V（低漏电流，有利于高阻抗电路）
- 耗散功率 Pd：410mW（典型工况下器件允许耗散功率）
- 动态阻抗 Zzt：80Ω；Zzk：300Ω（较低的 Zzt 有利于负载变化时维持稳定电压）
- 工作结温范围：-55℃ ～ +150℃
三、主要特点与优势
- 精度好：标称 30V、±2% 公差适合对稳压精度有一定要求的应用。
- 低漏电流：100nA 的反向电流使其在高阻电路和待机功耗敏感场景表现优良。
- 小封装、高密度：SOD-123 表面贴装，利于自动化贴装与板上空间优化。
- 宽温度性能：适应 -55℃ ～ +150℃ 的工业级温度要求。
四、典型应用
- 30V 基准与局部稳压电源（配串联限流电阻使用）
- 信号线/电压钳位与过压保护
- 仪表与传感器接口电路中的参考源
- 工业控制、通信设备和消费电子中需稳定电压的子模块
五、使用建议与注意事项
- 功率与散热：410mW 为器件最大耗散能力，实际应用中应考虑环境温度与印制板散热，必要时降低通过器件的电流或增加散热面积。
- 限流电阻配置：使用时常配串联电阻以限制电流，计算时以最大功耗和最高工作电压为依据。
- 布局：稳压二极管应尽量靠近被保护或被稳压节点放置，配合并联去耦电容可抑制瞬态噪声。
- 焊接与封装：SOD-123 适用回流焊工艺，请遵循厂商推荐的焊接曲线和温度限制，避免反复高温应力。
六、可靠性与选型提示
在设计选型时，除考量标称稳压和公差外，应关注动态阻抗（Zzt/Zzk）对负载瞬变的影响及漏电流对系统静态功耗的贡献。若电路对稳压噪声和瞬态响应要求更高，可选用阻抗更低或功耗更大的器件；若空间与成本受限，BZT52-B30 在小功率稳压场合为稳妥的平衡选择。

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.
