BZT52C8V2(8.2V)稳压二极管产品概述

一、产品简介

BZT52C8V2 为单只独立式稳压二极管,标称稳压值 8.2V,由扬杰(YANGJIE/扬杰)提供,封装为 SOD-123。该器件适用于小功率稳压、参考电压源、浪涌/过压钳位以及一般的电压保护应用,体积小、成本低,适合表面贴装自动化生产。

二、主要参数

  • 稳压值(标称):8.2V
  • 稳压值范围:7.7V ~ 8.7V
  • 反向漏电流 Ir:700 nA @ 5V
  • 耗散功率 Pd:500 mW(最大)
  • 稳态阻抗 Zzt:15 Ω
  • 膝部阻抗 Zzk:80 Ω
  • 工作结温:-55 ℃ ~ +150 ℃
  • 封装:SOD-123(单只、贴片)

三、电性能解析

  • 稳压精度:标称 8.2V,器件存在制造公差,典型批次落在 7.7–8.7V 范围内,设计时应考虑该范围对系统容差的影响。
  • 漏电流:在较低反向电压下漏电流仅数百纳安,适合对静态功耗或偏置电流敏感的电路。
  • 动态阻抗:Zzt = 15 Ω 表明在测定电流下的稳压动态响应较好,负载变化时稳压能力受限于此阻抗;Zzk = 80 Ω 表示在膝部电流附近对电压突变较敏感,应避免在该区域长期工作。
  • 功率限制:器件最大耗散功率为 500 mW,最大允许稳流 Iz_max ≈ Pd / Vz = 0.5 W / 8.2 V ≈ 61 mA(理论极限,不建议长期工作于此点)。

四、使用与设计建议

  • 串联限流电阻计算(齐纳稳压器常用):R = (Vin_min − Vz) / (IL + Iz),其中 IL 为负载电流,Iz 为保持稳压所需的齐纳电流。
  • 功率余量:为保证可靠性及温升控制,建议实际工作耗散不超过最大 Pd 的 60–70%(即建议 ≤ 300–350 mW);相应地限制 Iz。
  • 热管理:SOD-123 体积小,热阻相对较高,布局时应增大铜箔散热面积并避免把热源集中在封装周围。
  • 并联/串联:不建议直接并联多只以提高功率,因参数差异会导致电流分配不均;需要并联时应加阻抗均衡元件。

五、封装与可靠性

SOD-123 适合自动贴装与回流焊工艺,器件在 -55 ℃ 至 +150 ℃ 结温范围内可长期工作。焊接、回流温度应遵循供应商的焊接曲线与湿敏等级(MSL),存储与搬运注意防潮与静电防护。

六、典型应用场景

  • 嵌入式电源旁路与参考电压源
  • 小功率线性稳压/基准电路
  • 信号线或数据线的过压钳位保护
  • 便携设备、电池管理中的简单电压限制

七、选型与注意事项

  • 若系统对稳压精度或噪声有更高要求,请考虑具有更低动态阻抗和更窄容差的齐纳或参考源器件。
  • 在高温或连续较大电流环境下,应选择更高功率封装(如 DO-214 或 SOD-123F 等)或采用并联散热设计并参考厂商完整数据手册。
  • 采购时确认标称与极限参数(Pd、Ir、温度范围)与批次一致,必要时索取样片与完整规格书做评估。

如需样例电路计算(给定 Vin、负载电流 IL、所需稳压裕量)或推荐同系列不同功率/精度的备选型号,我可以根据具体工况提供详细设计计算与选型建议。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
