BZT52C11S 稳压二极管产品概述

一、产品基本属性

BZT52C11S是MDD品牌推出的独立式稳压二极管,核心定位为小功率电子设备的电压稳定、基准电压提供及简易过压保护。产品采用SOD-323小型表面贴装封装,体积紧凑,适配高密度PCB布局需求,是便携电子、低功耗模块等场景的常用基础器件。

二、核心电气参数

该型号稳压二极管的关键参数明确,覆盖多数常规稳压应用:

  • 稳压值:标称值11V,实际工作范围10.4V~11.6V(±5%精度),满足普通电路的电压稳定需求;
  • 反向漏电流(Ir):反向电压8V时仅100nA,漏电流极低,可有效降低待机功耗,适配电池供电设备;
  • 耗散功率(Pd):最大200mW,无需额外散热设计,适配小功率电路;
  • 动态阻抗(Zzt):30Ω,稳压性能稳定,输出电压波动小,抗负载变化能力较强。

三、封装与物理特性

SOD-323封装是该产品的核心物理优势:

  • 尺寸规格:约1.6mm(长)×0.8mm(宽)×0.6mm(厚),无引脚设计,节省PCB空间;
  • 贴装兼容性:支持自动贴装(回流焊、波峰焊),生产效率高,适合批量制造;
  • 机械强度:封装结构紧凑,抗振动、抗冲击性能较好,适配移动电子设备的复杂使用环境。

四、典型应用场景

基于参数与封装特点,BZT52C11S适用于以下场景:

  1. 便携电子设备:如智能手机、蓝牙耳机、智能手环等的辅助稳压电路,为传感器、小模块提供稳定11V基准;
  2. 小型电源模块:5V/12V电源的局部稳压,避免电压波动影响后级电路;
  3. 传感器电路:作为压力、温度传感器的基准电压源,保证信号采集精度;
  4. 低功耗电子:如遥控器、电子手表的电压调节,低漏电流特性降低待机功耗;
  5. 过压保护:串联限流电阻后,可作为简易过压保护器件,防止后级元件因电压过高损坏。

五、性能优势

对比同类小功率稳压二极管,BZT52C11S具备以下优势:

  • 低功耗特性:100nA反向漏电流,待机时几乎无额外损耗,适配电池供电设备;
  • 宽温稳定:常规工作温度范围-55℃~150℃(符合工业级标准),可在极端环境下稳定工作;
  • 成本效益:封装体积小、价格适中,适合批量应用,降低系统总成本;
  • 可靠性高:经过温度循环、振动测试等常规可靠性验证,长期工作稳定性好。

六、使用注意事项

为保证产品性能与寿命,需注意以下要点:

  1. 极性安装:稳压二极管需反向接入电路(阴极接电源正极,阳极接负极),正向接入无法实现稳压功能;
  2. 限流电阻:必须串联合适的限流电阻,避免过流损坏。计算方法:( R=(V_{in}-V_z)/I_{max} ),其中( V_z=11V ),( I_{max}≈18mA )(( Pd=200mW ));
  3. 焊接规范:回流焊峰值温度不超过260℃,回流时间不超过30秒,避免高温损坏封装;
  4. 环境温度:若应用环境温度超过100℃,需适当降低耗散功率(每升高1℃,Pd降低约1.3mW);
  5. 选型匹配:确认系统所需稳压值、功耗与该型号参数匹配,避免选型错误。

该产品凭借紧凑封装、稳定性能及低功耗特性,成为消费电子、工业控制等领域小功率稳压场景的可靠选择。

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.

Replenishment inquiry Typical RFQ workflow
