BZT52C10S稳压二极管产品概述

一、产品定位与核心价值

BZT52C10S是DOWO(东沃)品牌推出的小型表面贴装稳压二极管,属于标准稳压管系列中的10V规格产品。其核心价值在于:通过紧凑封装实现稳定电压输出,兼顾低功耗、高可靠性,适配各类小型化电子设备的电压调节需求,是低功率稳压场景的高性价比选择。

二、关键电气参数详解

该器件的电气参数经过严格测试,核心参数直接决定应用范围,具体解析如下:

2.1 稳压特性参数

  • 标称稳压值(Vz):10V(典型值),是器件反向击穿后稳定输出的电压基准;
  • 稳压值范围:9.4V~10.6V(公差±6%),覆盖批量生产中的器件偏差,满足一般精度需求;
  • 动态阻抗(Zzt):20Ω(测试条件:Iz=5mA),表示稳压状态下输出电压随电流变化的敏感程度——阻抗越小,电压稳定性越好;
  • 测试阻抗(Zzk):150Ω(测试条件:Iz=1mA),反映低电流下的稳压特性,适用于轻负载场景参考。

2.2 功耗与电流特性

  • 最大耗散功率(Pd):200mW,是器件允许的最大总热功耗,决定最大工作电流上限:
    最大稳压电流Izmax≈Pd/Vz=200mW/10V=20mA(实际建议不超过15mA,留安全余量);
  • 反向漏电流(Ir):200nA(测试条件:Vr=5V,远低于稳压值),反向截止时漏电流极小,有效降低静态功耗,适合电池供电设备。

三、封装与物理特性

BZT52C10S采用SOD-323封装(小型表面贴装),符合行业标准:

  • 尺寸规格:长1.6mm±0.1mm、宽0.8mm±0.1mm、高0.7mm±0.1mm,引脚间距0.65mm±0.1mm;
  • 封装优势:体积紧凑,适配高密度PCB布局(如智能手机、智能穿戴的微型电路);
  • 环保特性:无铅工艺,符合RoHS 2.0、REACH标准,满足出口及高端设备要求。

四、典型应用场景

结合参数特性,BZT52C10S适用于以下低功率稳压场景:

  1. 便携式电子设备:蓝牙耳机、智能手环的传感器偏置电压(10V稳定参考)、低功率电源模块稳压;
  2. 小型电源电路:DC-DC降压模块的输出辅助稳压(如12V转10V)、线性稳压器的前置稳压;
  3. 传感器与测量电路:为温度/压力传感器提供稳定偏置电压,确保测量精度;
  4. 消费电子辅助电路:LED指示灯驱动的电压钳位、遥控器电路的电压稳定。

五、选型与使用注意事项

为确保可靠工作,需注意以下要点:

  1. 电流范围控制:工作电流介于Izmin(≈1mA)与Izmax(≤20mA)之间,避免过流过热;
  2. 反向偏置要求:必须工作在反向击穿状态(正向无稳压功能),电路需保证反向电压高于稳压值;
  3. 散热设计:Pd=200mW较小,无需额外散热片,但PCB引脚需可靠焊接,避免虚焊过热;
  4. ESD防护:SOD-323封装对静电敏感,操作时需佩戴防静电手环、使用防静电工具;
  5. 精度匹配:若需更高精度(如±1%),可从9.4V~10.6V范围中筛选符合需求的器件。

六、总结

BZT52C10S稳压二极管凭借紧凑封装、低功耗、稳定稳压的特点,成为小型化电子设备中低功率稳压场景的优选器件。其参数覆盖常规应用需求,性价比突出,适用于消费电子、便携式设备、传感器电路等领域,是工程师选型时的可靠选择。

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.
