BZT52C36S 产品概述
一、产品简介
BZT52C36S 是 CJ（江苏长电/长晶）出品的一款独立式稳压二极管，标称稳压值 36V，工作范围 34V～38V，常用于小功率电压基准、瞬态钳位和信号保护场合。器件采用 SOD-323 表面贴装封装，体积小、便于自动化贴装。
二、主要技术参数
- 稳压值（标称）：36V
- 稳压值（范围）：34V～38V
- 阻抗 Zzk：350Ω（特征阻抗）
- 阻抗 Zzt：90Ω（在指定测试条件下的阻抗）
- 反向电流 Ir：100nA @ 25.2V
- 最大耗散功率 Pd：200mW
- 封装：SOD-323（贴片）
- 器件配置：独立式（二极管形式）
三、特性与优势
- 小尺寸、低功耗：SOD-323 封装配合 200mW 耗散，适合空间受限、功耗要求低的应用。
- 稳压值适中：36V 稳压用于中等电压基准或作为系统高压侧的保护管。
- 低反向漏流：在 25.2V 情况下 Ir 为 100nA，适合对漏电流敏感的电路。
- 可靠性高、成本低：适用于批量生产的保护与偏置用途。
四、典型应用
- 过压保护与钳位（输入保护、接口保护）
- 电路偏置与参考（非高精度电压基准）
- 浪涌吸收与稳压辅助（与限流电阻配合）
- 小功率开关电源、监控电路、工业控制板等
五、使用与焊接建议
- 热耗散管理：Pd 为 200mW，SOD-323 热阻较大，长期工作时应注意降低结温，可通过 PCB 铜箔散热或限流降低管上耗散。
- 测试与偏置：在实际电路中测量稳压值应在厂家指定测试电流下进行，并关注动态阻抗随电流的变化。
- 温度影响：反向电流和稳压值会随温度上升而变化，设计时预留余量。
- 焊接工艺：推荐使用回流焊，遵循厂家温度曲线，避免长时间过高温度。
六、选型与替代
本型号适合对稳压精度要求不苛刻、注重体积与成本的场合。如需更低阻抗或更高功率，应考虑更大封装或功率型稳压管；如需更高稳压精度，可选择分选等级或精密参考源。
七、注意事项
在设计时应综合考虑最大耗散、工作电流、环境温度与热路径，避免长时间在接近额定 Pd 下工作；对关键参考点建议做实验验证稳压特性及漏电随温度的变化。购买时确认 CJ（江苏长电/长晶）原装渠道与规格书最新版本以确保参数一致。

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.
