BZT52C3V3稳压二极管产品概述

一、核心参数总览

BZT52C3V3是一款独立式稳压二极管,核心参数围绕3.3V稳压需求设计,关键指标如下:

  • 稳压特性:标称稳压值3.3V,工作范围内稳压值保持3.1V~3.5V的窄波动范围,避免电压偏差影响电路稳定性;
  • 功耗与电流:最大耗散功率500mW,反向漏电流仅5μA(测试条件:1V反向电压),低功耗适配小功率电路;
  • 动态性能:动态阻抗Zzt为85Ω,稳压响应快速,可有效抑制瞬时电压波动;
  • 温度适应性:工作结温范围覆盖-65℃~+150℃,满足极端环境下的稳定工作;
  • 封装形式:采用SOD-123表面贴装封装,体积紧凑(典型尺寸2.4×1.6mm),适配小型化电路设计。

二、关键性能特点

  1. 稳压精度可控:标称3.3V的波动范围(3.1V~3.5V)较窄,避免因电压偏差导致后端敏感元件(如MCU、传感器)工作异常,适合对电压稳定性要求高的模块;
  2. 低功耗低漏电流:反向漏电流仅5μA(1V测试),待机或低负载状态下功率损耗极低,可延长设备续航时间;
  3. 高功率密度封装:SOD-123小封装承载500mW耗散功率,实现“小体积大能量”,适配高密度电路板(如智能穿戴、蓝牙设备);
  4. 宽温环境兼容:-65℃+150℃的结温范围,覆盖工业级(-40℃+85℃)、汽车级(-40℃~+125℃)等极端场景,无需额外散热或温度补偿;
  5. 响应速度快:85Ω动态阻抗确保稳压响应迅速,可抑制电路中的瞬时电压尖峰,保护后端元件不受损坏。

三、封装与可靠性设计

SOD-123封装是BZT52C3V3的核心设计亮点:

  • 自动化贴装适配:表面贴装工艺支持高速自动化生产,降低人工成本,适合大规模批量应用;
  • 机械可靠性:封装引脚与芯片连接牢固,抗振动、抗冲击性能优异,可应对车载、工业控制等振动环境;
  • 热管理优化:封装结构优化热传导路径,即使在150℃高温下仍能稳定散热,避免结温过高导致器件失效。

四、典型应用场景

BZT52C3V3因参数适配性强,广泛应用于以下领域:

  1. 消费电子:智能穿戴(手表、手环)、蓝牙音箱、小型家电的电源稳压模块,满足低功耗、小体积需求;
  2. 工业控制:传感器节点、PLC模块的辅助供电稳压,适配工业环境温度范围;
  3. 汽车电子:车载辅助电路(仪表盘背光、胎压传感器供电),兼容汽车级温度与振动要求;
  4. 通信设备:小型路由器、无线AP的电源滤波稳压,确保信号传输稳定。

五、品牌与品质保障

该器件由FOSAN(富信)半导体生产,富信作为国内专注于半导体分立器件的厂商,产品具备以下优势:

  • 环保合规:符合RoHS、REACH等国际环保标准,无铅、无有害物质;
  • 参数一致性:批量生产中稳压值、漏电流等参数偏差小,适合大规模工业应用;
  • 技术支持:提供完善的 datasheet、应用手册与售后支持,解决客户设计中的问题。

BZT52C3V3凭借“稳定、高效、紧凑”的特性,成为3.3V稳压场景的高性价比选择,覆盖消费电子、工业、汽车等多领域应用。

Sourcing availability signal

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
