BZT52C4V7稳压二极管产品概述

一、产品基本定位与核心身份

BZT52C4V7是Hottech(合科泰) 推出的一款独立式表面贴装稳压二极管,属于中低压稳压系列,主要面向对体积、功耗有严格要求的电子电路设计场景。该型号以4.7V标称稳压值为核心,兼顾宽温适应性与小电流稳压性能,是消费电子、工业控制等领域的常规选型器件。

二、核心电气参数详解

该型号的电气参数精准匹配中低功率稳压需求,关键参数如下:

  1. 稳压值特性:标称稳压值为4.7V,实际工作范围覆盖4.4V~5.0V,满足多数电路对中等精度稳压的要求;
  2. 反向漏电流:反向电压2V时,漏电流仅3μA,远低于常规稳压管的漏电流指标,有效降低静态功耗;
  3. 功耗限制:最大耗散功率为350mW,需结合电路工作电流(Izm≈350mW/4.7V≈74mA)控制使用条件;
  4. 动态阻抗:测试电流下动态阻抗(Zzt)为80Ω,最大工作电流下动态阻抗(Zzk)为500Ω,小电流场景下稳压稳定性优异;
  5. 温度适应性:工作结温范围覆盖**-65℃~+150℃**,支持极端环境下的长期稳定运行。

三、封装与物理特性

BZT52C4V7采用SOD-123 表面贴装封装,具备以下优势:

  • 小体积设计:封装尺寸紧凑(典型值1.6mm×0.8mm×0.8mm),适配高密度PCB布局,尤其适合便携式设备;
  • 贴装兼容性:引脚间距符合自动化贴装标准,可兼容回流焊、波峰焊等工艺,降低生产难度;
  • 散热适配:虽为小封装,但350mW功耗在SOD-123封装的散热能力范围内,满足常规小功率应用需求。

四、典型应用场景

结合参数与封装特性,BZT52C4V7主要应用于以下场景:

  1. 小电流稳压电路:如MCU电源参考电压、传感器偏置电压、低功耗模块供电稳压;
  2. 电压基准源:作为精度要求中等的基准(如ADC参考电压),替代成本较高的精密基准;
  3. 工业控制电路:宽温范围适配户外/车载等高低温环境,用于信号调理电路稳压;
  4. 便携式电子设备:手机、智能穿戴、蓝牙耳机等小体积产品的电源辅助稳压;
  5. 过压保护辅助:利用反向击穿特性,辅助保护低压敏感器件(需配合限流电阻)。

五、品牌与可靠性说明

Hottech(合科泰)作为国内半导体行业的成熟厂商,BZT52C4V7具备以下可靠性保障:

  • 环保合规:符合RoHS 2.0、REACH等国际环保标准,无铅无卤;
  • 可靠性测试:通过高低温循环(-65℃~+150℃,1000次)、湿度老化(85℃/85%RH,1000h)等可靠性试验;
  • 批量一致性:采用自动化生产工艺,参数一致性控制在±0.3V稳压范围,适合量产应用。

六、选型与替换参考

若需替换BZT52C4V7,需注意以下要点:

  • 参数匹配:优先选择稳压值4.4V~5V、Pd≥350mW、SOD-123封装的器件,如部分厂商的1N4731(需注意封装差异) 或同系列ZXMM5.1V(需确认稳压范围);
  • 应用场景适配:若为极端宽温场景,需确认替换器件的结温范围是否覆盖-65℃~+150℃;
  • 功耗限制:替换器件的Pd需不低于350mW,避免功率过载。

该型号凭借平衡的性能与成本优势,成为中低端稳压电路的高性价比选择,广泛应用于各类电子终端产品。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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
