BZT52C5V6T 产品概述
一、产品简介
BZT52C5V6T 是 BORN（伯恩半导体）推出的一款小功率稳压二极管，标称稳压值为 5.6V，单只独立封装，适用于空间受限的表面贴装电路。该器件以其体积小、稳定性好、成本低的特点，常用于基准电压、浪涌/反向保护以及小电流稳压场合。
二、主要电气参数
- 稳压值（标称）：5.6V
- 稳压值范围：5.2V ～ 6.0V
- 耗散功率 Pd：200mW（器件最大功耗）
- 反向电流 Ir：1µA @ 2V（低电压下的反向漏泄）
- 阻抗 Zzt：40Ω（稳态动态阻抗）
- 阻抗 Zzk：400Ω（转折/低电流条件下的动态阻抗）
- 二极管数量：1 个（独立式）
三、性能特点
- 小体积、SMD 封装（SOD-523），适合高密度贴片应用。
- 低反向漏电流，适用于低功耗电路中的基准源和偏置电路。
- 在额定功耗范围内提供相对稳定的稳压性能；Zzt 与 Zzk 值提示在不同工作点下电压稳定性会有明显变化，适合低电流或信号级稳压应用。
四、封装与物理特性
封装：SOD-523，为超小型表面贴装封装，适合自动贴装与回流焊工艺。由于封装尺寸小，热阻较大，实际使用时需要关注热量集中与功耗限制。
五、典型应用
- 小电流基准电压源与参考电路。
- 信号链的过压钳位与浪涌保护。
- 微型电源的局部稳压与偏置电路。
- 低功耗或便携设备中作为低成本稳压元件。
六、设计与使用注意事项
- 功耗限制：器件最大耗散功率为 200mW，使用时必须保证通过稳压管的功率 Pd = Vz × Iz（并加上额外电压降功耗）不超过额定值。建议在实际工作点上留有安全余量并考虑环境温度的影响。
- 串联限流：稳压管需配合串联限流电阻使用，选择时按 R ≥ (Vin − Vz) / Iset 计算，并确保 (Vin − Vz)×Iset ≤ Pd。
- 热管理：SOD-523 封装热容小，长时间大电流工作会引起结温上升，应尽量缩短导线长度、在 PCB 上提供适当的铜箔散热或避免在高温环境下长期满载工作。
- 动态阻抗：Zzt（40Ω）和 Zzk（400Ω）表明在不同电流区间电压会有显著变化，若需要低噪声、低漂移的电压源，应考虑使用专用参考芯片或并联滤波/缓冲电路。
七、替代与选型建议
在需要更高功率、更低动态阻抗或更精确稳压的场合，可选用功率等级更高或精密基准源替代。若空间允许且要求更高稳压精度，优先选择功耗和阻抗指标更符合系统需求的器件。购买时确认 BORN 原厂/授权代理以保证质量与一致性。

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.
