BZT52C11稳压二极管产品概述

一、基本身份与封装信息

BZT52C11是伯恩半导体(BORN) 推出的一款表面贴装稳压二极管,型号命名遵循行业通用逻辑:“BZT52”为系列标识,“C11”明确标称稳压值为11V。

其采用SOD-123封装,这是一种小型化表面贴装形式,尺寸约为2.5mm×1.2mm×1mm,体积仅为常规插件稳压管的1/5左右,重量不足0.1g。该封装适配高密度PCB布局,可有效节省电路空间,尤其适合便携化、模块化的电子设备设计。

二、核心电参数特性详解

BZT52C11的参数针对常规稳压场景优化,关键特性如下:

1. 稳压值与精度

标称稳压值为11V,实际工作范围为10.4V~11.6V(精度约±5.5%),该范围在典型测试电流(如5mA)下测得,可满足大多数对稳压精度要求不苛刻的电路需求(如辅助电源稳压、简单参考电压生成)。

2. 反向漏电流(Ir)

最大反向漏电流仅为100nA,远低于同类器件常见的μA级水平。低漏电流意味着反向截止状态下几乎无额外功耗,特别适合电池供电的便携设备,可有效延长待机时间。

3. 耗散功率(Pd)

最大耗散功率为500mW(0.5W),是器件允许的最大功率损耗。设计电路时需结合实际工作电流与电压差计算余量(如工作电流10mA时,允许电压差≤50V),确保安全运行。

4. 动态阻抗

包含两个关键参数:

  • Zzt(测试电流下动态阻抗):20Ω → 电流变化1mA时,稳压值波动仅约20mV,稳压性能稳定;
  • Zzk(拐点电流下动态阻抗):150Ω → 反向击穿拐点处的阻抗表现优异,可快速进入稳压状态。

三、典型应用场景

BZT52C11凭借小体积、低功耗、稳定稳压的特性,广泛应用于以下场景:

1. 小型电源稳压

如12V直流电源的辅助稳压环节:当输入电压波动(如11V~13V)时,可将输出稳定在11V左右,保护后级MCU、传感器等敏感电路。

2. 便携式电子设备

智能手机、蓝牙耳机、智能手环等产品的低功耗电路中,SOD-123封装适配紧凑PCB空间,100nA漏电流减少电池待机损耗,保障续航。

3. 传感器参考电压

工业温湿度传感器、环境监测模块中,作为简单参考电压源稳定11V输出,为信号采集提供可靠基准(满足一般精度需求)。

4. 简单过压保护

利用反向击穿特性,当电路电压超过11V时反向导通,钳位电压至11V左右,避免后级电路过压损坏(适用于成本敏感的简单保护场景)。

四、产品应用优势

相较于同类器件,BZT52C11具有以下优势:

1. 小体积适配高密度设计

SOD-123封装可在有限空间内实现稳压功能,适合智能穿戴、小型家电等紧凑产品。

2. 低功耗延长续航

100nA漏电流显著降低待机功耗,在电池供电设备中可提升续航10%~15%(对比部分μA级漏电流器件)。

3. 稳压性能稳定可靠

20Ω动态阻抗减少电流波动对电压的影响,电路设计无需额外补偿电路,简化开发流程。

4. 成本效益突出

作为伯恩半导体常规产品,供货稳定、成本合理,适合批量应用于消费电子、工业控制等领域的低成本电路。

BZT52C11是一款性能均衡的稳压二极管,核心参数覆盖常规稳压与保护需求,是便携设备、小型电源等场景的实用选择。

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.
