稳压二极管 BZT52C9V1S 产品概述

一、产品基本定位

BZT52C9V1S是一款小功率表面贴装稳压二极管,主打9.1V标称稳压值,属于常用低压稳压范畴。其设计兼顾小型化与基础稳压性能,适配便携式设备、小型电子模块等对空间敏感的应用场景,是为MCU、传感器等敏感元件提供稳定电压基准或低压稳压的经济高效选择。

二、核心电性能参数详解

该器件的关键参数直接决定其应用适配性,具体如下:

2.1 稳压值与精度

  • 标称稳压值:9.1V(稳压管核心参数,指反向击穿后稳定输出的电压);
  • 精度范围:±5%,对应实际稳压值区间为8.5V~9.6V(满足一般电路对电压稳定度的需求,无需额外高精度校准);
  • 测试条件:行业通用测试电流(如BZT52系列典型Izk=5mA,虽未明确标注但为常规稳压管测试标准)。

2.2 反向漏电流(Ir)

  • 参数值:500nA(反向偏置6V时的漏电流);
  • 意义:漏电流极小,说明反向截止特性优异,低功耗场景下几乎无额外损耗,适合电池供电的便携式设备。

2.3 最大耗散功率(Pd)

  • 参数值:200mW;
  • 计算参考:最大允许工作电流Izm≈Pd/Vz=200mW/9.1V≈21.9mA(实际应用中需控制工作电流在此范围内,避免过热损坏)。

2.4 动态阻抗(Zzt)

  • 参数值:30Ω;
  • 意义:稳压区的动态阻抗(电压变化与电流变化的比值),值越小稳压性能越稳定。30Ω属于小功率稳压管的常规水平,可满足大多数基础稳压需求。

三、封装与典型应用场景

3.1 封装规格

该器件采用SOD-323封装(极小表面贴装封装),尺寸约为1.6mm×0.8mm×0.6mm,适配自动化贴片生产,同时大幅节省电路板空间,适合高密度集成设计。

3.2 典型应用

  1. MCU/ADC基准电压源:为微控制器的模拟数字转换(ADC)模块提供稳定的9V级基准电压,提升采样精度;
  2. 小型电源稳压:针对输入电压略高于9.1V的场景(如12V电源降压),稳压输出稳定电压,保护后级敏感元件;
  3. 传感器模块供电:为温湿度、光电等低功耗传感器提供稳定工作电压,避免电压波动影响测量准确性;
  4. 低功耗电路过压保护:作为电压钳位元件,防止电路中瞬间过压损坏元件(如电池充放电时的电压尖峰)。

四、品牌与可靠性说明

4.1 品牌背景

该器件由MDD(国内知名半导体厂商)生产,专注于分立器件的研发与制造,产品覆盖稳压管、二极管、三极管等,广泛应用于消费电子、工业控制、汽车电子等领域。

4.2 可靠性特点

  • 符合RoHS环保标准,无铅无镉,适配绿色电子产品设计;
  • 反向漏电流长期稳定性好,经批量测试验证,可满足消费级/工业级常规可靠性要求(常规工作温度范围-55℃~150℃);
  • 封装抗机械应力性能优异,适合振动环境下的应用(如便携式设备)。

五、使用与选型注意事项

  1. 极性确认:必须反向接入电路(阴极接正电源,阳极接负电源),正向接入仅为普通二极管,无稳压作用;
  2. 电流限制:工作电流需控制在5mA~22mA(参考Izk与Izm)之间,低于5mA稳压性能不稳定,超过22mA易过热损坏;
  3. 焊接规范:SOD-323封装焊接时,回流焊温度不超过260℃(时间≤10秒),手工焊接温度≤350℃(时间≤3秒),避免损伤器件;
  4. 精度匹配:若需更精准稳压值,可根据8.5V~9.6V的范围筛选器件,适配特定电路需求。

该器件以其小体积、低功耗、稳定的稳压性能,成为小型电子系统中基础稳压与过压保护的高性价比选择。

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.
