BZT52C2V4(BORN 伯恩)产品概述

一、产品简介

BZT52C2V4 是 BORN(伯恩半导体)推出的一款低功耗独立式稳压二极管,采用 SOD-123 塑料封装。标称稳压值为 2.4V,产品以小尺寸、低成本和良好的温度稳定性为特点,适用于对稳压精度和功耗要求不高的便携、消费类及工业低功耗电路中作为基准电压或简单稳压元件使用。

二、主要电气参数(关键规格)

  • 稳压值(标称):2.4V
  • 稳压值范围:2.2V ~ 2.6V
  • 反向电流 Ir:50 μA(最大)
  • 耗散功率 Pd:500 mW(最大)
  • 动态阻抗 Zzt:100 Ω
  • 膝部阻抗 Zzk:600 Ω
  • 二极管数量:1(独立式)

这些参数体现了器件在反向(稳压)工作区的基本性能:较低的标称电压、有限的功耗能力以及中等的动态阻抗,适合低电流、低功耗场合。

三、封装与物理特性

  • 封装形式:SOD-123 塑料封装(小型表面贴装)
  • 外壳材料:模压塑料,环氧树脂等级 UL 94V-0(阻燃)
  • 极性标识:包装上以色带标记阴极(便于正确贴装)

SOD-123 具有体积小、易于自动贴片和回流焊接的优点,适合空间受限的电路板应用。

四、典型应用场景

  • 低功耗参考电压源与简单稳压电路
  • 便携仪器的基准或偏置电路
  • 电平移位、小信号钳位与过压保护(低能量瞬态)
  • 传感器前端与信号调理中的稳定偏置
  • 电池监测电路中的低压参考

该器件不适合替代大电流或高精度参考源的场合。

五、设计与使用注意事项

  • 功耗与电流限制:理论上 Iz_max ≈ Pd / Vz ≈ 500 mW / 2.4 V ≈ 208 mA,但实际可允许的持续电流需考虑封装散热与环境温度,建议在稳态设计中采用远低于该理论值的工作电流以保证可靠性。
  • 动态阻抗影响稳压精度:Zzt 为 100 Ω,表明在负载或电流变化时输出电压有明显摆幅,若要求高精度稳压需加并联运算放大器或使用更低阻抗的参考源。
  • 反向泄漏:Ir 最大 50 μA,设计时应考虑在高阻抗、微安级信号路径上可能引入的误差。
  • 布局与散热:尽量使用完整的铜面或散热通孔来提高封装散热性能;保持靠近器件的地铜面连续以帮助散热。
  • 焊接与存储:SOD-123 支持常规回流焊接流程,封装环氧树脂符合 UL94V-0,长期存储应避免潮湿以及极端温度,贴片后注意焊接温度窗与制造厂提供的工艺规范。
  • 极性识别:安装时注意色带为阴极标识,错误极性会导致不能稳压或损坏器件。

六、选型建议与替代

若电路要求更低的动态阻抗、更高的功耗或更精确的稳压,请选择额定功率更高(Pd 更大)或用低阻抗、高精度参考源(如带隙参考、精密基准IC)。在空间受限且电流较低的场合,BZT52C2V4 是经济有效的选择;若系统存在较大温度或电流波动,需重新评估稳压元件规格。

总结:BZT52C2V4(BORN)以紧凑的 SOD-123 封装、2.4V 的标称稳压以及 500 mW 的功耗能力为特色,适合低功耗、低成本的参考和稳压应用。合理评估实际工作电流、散热条件和稳压精度要求后,可在多种便携和工业电子产品中可靠使用。

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.
