BZT52C3V0 产品概述
一、产品简介
BZT52C3V0 是 GOODWORK（固得沃克）出品的一款独立式稳压二极管，标称稳压值 3.0V（实际公差范围 2.8V ~ 3.2V），采用 SOD-123 小型贴片封装。器件面向低功耗、小尺寸电路的基准和稳压、浪涌吸收及电压钳位等应用。
二、主要电气参数
- 标称稳压：3.0V（范围 2.8V ~ 3.2V）
- 反向漏电流 Ir：10 μA @ 1.0V
- 耗散功率 Pd：500 mW（封装与散热条件相关，需参照实际 PCB 散热设计）
- 小信号阻抗：Zzk = 600 Ω（低电流区特性）
- 稳态动态阻抗：Zzt = 95 Ω（工作点附近的小信号阻抗）
三、产品特性与优势
- 体积小、易于自动贴装，适合空间受限的便携设备。
- 低至微安级反向漏电，适合待机与低功耗电路。
- 合理的稳压精度（2.8V~3.2V）满足多数小信号基准需要。
- SOD-123 封装兼顾机械强度与热散能力，适合中等功率工作点。
四、典型应用场景
- 低功耗供电轨稳压（作为并联稳压元件）
- 电平钳位、信号保护和过压防护
- 偏置源和参考电压（模拟前端、传感器接口）
- 电池供电器件的保护与简易稳压
五、使用与选型建议
- 在作为并联稳压器使用时需串联限流电阻 R = (Vin − Vz) / Iz，以限制二极管电流。计算时同时验证二极管耗散 Pd = (Vin − Vz) × Iz，不超过 500 mW 并留有安全裕度。
- Zzk 与 Zzt 指示在不同电流区的阻抗差异，低电流时阻抗较大（600 Ω），稳态工作点阻抗较小（95 Ω），设计时注意负载变动对稳压精度的影响。
- 对温漂与精度敏感的场合，请结合完整数据表核对 Vz 随电流与温度的变化（Izt、TVC 等）。
- PCB 布局应提供充分散热铜面积和短回流路径，SOD-123 封装在高功率或高环境温度时需降额使用。
六、封装与可靠性
SOD-123 封装适合回流焊工艺，适用于自动化量产。长期可靠性依赖于热管理与工作点选择，建议在实际环境（温度、封装周围铜箔面积）下做过温与功耗验证。
总结：BZT52C3V0（GOODWORK）为小型、适用面广的 3V 稳压二极管，适合低功耗和空间受限的电子设计。选型时应关注实际工作电流、功耗与热散条件，并参照完整技术资料确认关键参数。

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.
