BZX584B15稳压二极管产品概述

一、产品核心定位与应用场景

BZX584B15是江苏长电(CJ)推出的独立式表面贴装稳压二极管,专为小功率电子设备的电压稳定、过压保护需求设计。其采用超小型SOD-523封装,适配高密度PCB布局,广泛应用于以下领域:

  • 消费电子:智能手机、智能穿戴、便携式音频设备的电源稳压模块;
  • 工业控制:小型传感器节点、PLC辅助电路的基准电压源;
  • 通信设备:无线模块、光纤收发器的过压钳位与电压稳定;
  • 宽温场景:户外监测设备、车载辅助电路(非动力系统)的极端温度稳压。

二、关键电气参数解析

BZX584B15的电气性能围绕“低功耗、高精度、宽温稳定”设计,核心参数如下:

1. 稳压与漏电流特性

  • 标称稳压值15V,稳压范围14.7V~15.3V(偏差±2%),满足多数小功率电路的基准精度要求;
  • 反向漏电流仅100nA(@10.5V反向电压):远低于稳压值(15V),非工作状态下功耗极低,可延长电池续航(适配便携式设备)。

2. 功率与阻抗性能

  • 最大耗散功率150mW:适配小功率电路的电压稳定需求,无需额外散热设计;
  • 动态阻抗:典型工作点阻抗Zzt=30Ω(稳压值下),转折区阻抗Zzk=200Ω,阻抗特性稳定,能有效抑制电压波动对输出的影响。

3. 温度适应性

工作结温范围覆盖**-55℃~+150℃**,可在工业高温、低温户外等极端环境下稳定工作,无需额外温度补偿电路,降低设计复杂度。

三、封装与可靠性设计

1. 封装特点

采用SOD-523封装,尺寸紧凑(约1.6mm×0.8mm×0.6mm),具备以下优势:

  • 适配高密度PCB布局,满足小型电子设备的空间限制;
  • 支持自动化贴装,提升生产效率;
  • 引脚焊接可靠性高,兼容回流焊工艺。

2. 品牌与可靠性

由江苏长电(国内半导体行业龙头企业)生产,产品符合RoHS环保标准,经过严格可靠性测试(温度循环、湿度老化、机械振动),确保长期使用性能稳定,故障率低。

四、典型应用电路示例

1. 基准电压源电路

将BZX584B15并联在直流电源输出端(串联1kΩ~10kΩ限流电阻),为MCU、ADC等提供稳定15V基准电压,配合10μF滤波电容可进一步抑制纹波。

2. 过压保护电路

并联在敏感电路(如传感器、通信模块)输入端,当输入电压超过15V时,稳压管击穿导通,将电压钳位在15V左右,保护后级电路免受过压损坏。

3. 开关电源滤波辅助

在开关电源输出端并联稳压管与0.1μF陶瓷电容,利用稳压管低阻抗特性,辅助电容抑制高频电压波动,提升输出稳定性。

五、选型优势总结

相较于同参数其他品牌稳压管,BZX584B15具备以下核心优势:

  • 宽温覆盖:-55℃~+150℃工作结温,适配工业/汽车级辅助电路;
  • 低静态功耗:100nA反向漏电流,适合电池供电设备;
  • 高性价比:长电品牌可靠性与亲民价格平衡性能与成本;
  • 小型化适配:SOD-523封装满足高密度设计需求。

该产品可作为小功率电路的稳压基准、过压保护元件,是消费电子、工业控制等领域的高性价比选择。

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
