BZT52C33S 产品概述
一、产品简介
BZT52C33S 是扬杰（YANGJIE）生产的一款小功率稳压二极管，标称稳压值 33V，封装为 SOD-323 贴片形式，适合体积受限的表面贴装电路中作为电压参考、浪涌钳位或偏置稳压元件使用。器件设计面向低功耗和小信号应用，兼顾温度稳定性与长期可靠性。
二、主要电气参数
- 标称稳压值（Vz）：33V（典型）
- 稳压值允许范围：31V ～ 35V
- 反向电流（Ir）：100nA @ 23.1V
- 耗散功率（Pd）：200mW（在推荐散热条件下）
- 动态阻抗 Zzt：80Ω（测试条件下）
- 膝部阻抗 Zzk：325Ω
- 工作结温范围：-55℃ ～ +150℃
三、性能特点与优势
- 低反向漏电，适合高阻抗电路作为精密参考或基准电压。
- 小封装（SOD-323），便于高密度 PCB 布局和自动贴装生产。
- 宽温度范围，适应工业及严苛环境。
- 中等动态阻抗，在滤波和稳压回路中能提供较稳定的电压钳位效果。
四、典型应用场景
- 电源保护：浪涌、过压钳位与瞬态吸收。
- 电压参考/偏置：在放大器、比较器输入等需要固定偏置的电路中。
- 便携式与电池供电设备：尺寸和功耗受限的稳压需求。
- 混合信号电路中的过压保护与电平限制。
五、选型与使用建议
- 耗散功率仅 200mW，使用时应注意热量分配与 PCB 散热设计，必要时留足铜箔热回流区并限制稳压二极管的工作电流。
- 稳压值有 31V～35V 的范围，需根据系统允许的最大/最小电压容差选择合适批次或进行实际测量校正。
- 对于需要低噪声或更高精度基准的场合，建议在稳压二极管后加入合适滤波或使用精密基准源。
- 注意器件的极性和 ESD 保护，贴装及回流焊工艺遵循厂商推荐。
六、包装与可靠性
SOD-323 小封装利于自动化装配，适配常规 SMT 生产线。器件工作结温范围宽，符合一般工业级可靠性要求。购买与设计时建议参考扬杰官方 datasheet 获取详细特性曲线、测试条件与焊接工艺参数，以确保在目标应用中的长期稳定性。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
