BZT52C3V3S稳压二极管产品概述

一、产品基本信息

FUXINSEMI(富芯森美)推出的BZT52C3V3S是一款独立式稳压二极管,采用SOD-323(封装代码SC-90) 表面贴装封装,专为低功耗、小型化电子设备的电压稳压与过压保护场景设计。该型号属于BZT52系列中的3.3V低压稳压规格,核心参数明确,适配消费电子、工业控制、汽车电子等多领域通用电路需求。

二、核心电气参数详解

BZT52C3V3S的关键参数聚焦低压稳压的稳定性与可靠性,具体如下:

  1. 稳压性能:标称稳压值为3.3V,稳压范围覆盖3.1V~3.5V,满足常见低压电路的基准电压或稳压需求;动态阻抗(Zzt)为95Ω,反映稳压管在工作电流变化时的电压波动——较低的动态阻抗意味着输出电压稳定性更好,减少对后续电路的干扰。
  2. 功耗与电流:最大耗散功率(Pd)为200mW,支持小功率电路的稳压需求;反向漏电流(Ir)为5uA(测试条件:反向电压1V),低漏电流设计可降低静态功耗,尤其适合电池供电设备。
  3. 温度特性:工作结温范围为**-55℃~+150℃**,覆盖工业级与部分汽车电子的温度需求,能在极端环境下保持稳定工作,无需额外温度补偿电路。

三、关键特性与优势

  1. 宽温适应性:-55℃至150℃的结温范围,可满足户外设备、工业控制等恶劣环境下的稳定运行,避免因温度变化导致的稳压值漂移。
  2. 小封装高密度:SOD-323封装尺寸小巧(典型尺寸1.6mm×0.8mm×0.6mm),适合智能手机、可穿戴设备等小型化产品的高密度PCB布局,节省空间的同时提升电路集成度。
  3. 稳定稳压性能:标称3.3V的稳压值与明确的3.1V~3.5V范围,便于电路设计时的选型与参数匹配;95Ω的动态阻抗确保负载电流小幅变化时,输出电压保持稳定。
  4. 低功耗设计:5uA的反向漏电流与200mW的最大耗散功率,适配IoT设备、智能传感器等低功耗场景,延长电池续航时间。

四、典型应用场景

  1. 消费电子稳压:智能手机、平板电脑、蓝牙耳机等设备的辅助电源稳压,为传感器、无线模块提供稳定的3.3V工作电压。
  2. 信号电路保护:作为过压钳位元件,用于音频、射频信号电路,防止静电或瞬态过压损坏IC芯片,提升电路可靠性。
  3. 工业控制基准源:工业PLC、传感器模块中的基准电压源,提供稳定的3.3V参考,确保测量与控制精度。
  4. 汽车电子辅助稳压:车载小功率电路(如仪表盘背光、传感器供电)的稳压,适配汽车环境的宽温需求(-40℃~125℃)。
  5. 电池供电设备:智能手环、智能门锁等低功耗设备的电压调节,平衡稳压需求与电池续航。

五、封装与可靠性说明

SOD-323封装采用表面贴装工艺,焊接兼容性好,可通过回流焊、波峰焊实现高效生产;封装材料耐温性强,配合宽结温范围,能承受多次温度循环而不失效。此外,该型号参数一致性较好,批量应用时可减少电路调试难度,提升产品良率。

BZT52C3V3S凭借其低压稳压、小封装、宽温适应性等特点,成为低功耗电子设备中稳压与保护的高性价比选择,适配多领域通用电路需求。

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
