BZT52C15 产品概述

一、简介

BZT52C15 是 BORN(伯恩半导体)推出的一款独立式稳压二极管,封装为 SOD-123。该器件以 15V 标称稳压值为设计目标,适合用于小功率电压基准、过压钳位和噪声抑制等场合。结构紧凑、响应快速,适合表面贴装工艺,方便在空间受限的电路板上实现稳压或限压功能。

二、主要参数

  • 稳压值(标称):15V
  • 稳压值范围:13.8V ~ 15.6V
  • 最大耗散功率 Pd:500 mW(环境与散热条件影响最大额定功率)
  • 反向电流 Ir:100 nA @ 10.5V(低偏压下漏电流小)
  • 阻抗(Zzk):200 Ω
  • 阻抗(Zzt):30 Ω
  • 封装:SOD-123(表面贴装)

三、特性与优势

  • 精准稳压:15V 标称,公差范围控制在 13.8V~15.6V,适合一般 15V 参考与钳位需求。
  • 低漏电流:在 10.5V 时反向电流仅 100nA,适合对静态功耗敏感的电路。
  • 快速响应:作为二极管结构,可实现快速电压钳位与瞬态抑制。
  • 小体积封装:SOD-123 占板面积小,利于高密度 PCB 布局与自动贴装生产。
  • 适用面广:独立式设计便于单点稳压、保护电路或与电阻配合构成简单的分流稳压器。

四、典型应用

  • 线性稳压与参考电压源的简易实现(限于小功率负载)。
  • 电源过压保护与输入端钳位,防止后级电路承受瞬态或异常升压。
  • 信号电路中的电平钳位、偏置网络与参考基准。
  • 工业控制、通信模块、小型家电以及便携式设备中的局部稳压。

五、选用与设计建议

  • 考虑耗散功率:器件最大耗散功率为 500 mW,实际设计时应计算稳压二极管的功耗 Pd = (Vin - Vz) × Iz 并留有余量;若环境温度较高或散热受限,应适当降低工作电流或选择更大功率器件。
  • 串联限流电阻计算:R = (Vin - Vz) / (Iz + IL),其中 Iz 为稳压管工作电流,IL 为负载电流。确保在最大输入电压情况下 Pd 不超过额定值。
  • 动态阻抗影响稳压精度:Zzt(30 Ω)与 Zzk(200 Ω)表明在测试电流与低电流区稳压性能不同,选择工作电流时需兼顾稳压稳定性与功耗。
  • 漏电流注意:低偏压下 Ir 在 10.5V 即为 100 nA,适合低泄漏场景,但在高温下漏电会上升,应在高温工况验证。

六、封装与可靠性

SOD-123 小型封装适合自动化表贴生产,焊接时注意控制回流温度曲线以保证可靠性。由于功率较小,器件周边应留出散热路径,避免在铜箔较少的区域长期承载高耗散。长期可靠性与温度漂移需参考整机工作环境并做必要的老化与温度循环测试。

七、检验与注意事项

  • 采购时确认规格书和批次一致,检验稳压值范围和泄漏电流指标。
  • 设计仿真与样机测试中,应在最坏工况(最高 Vin、最高环境温度)下验证稳压精度与功耗。
  • 储存与贴装按常规 SMD 器件注意防潮、防静电处理。

总结:BZT52C15(BORN,SOD-123)是一款面向小功率稳压和钳位应用的 15V 稳压二极管,低漏电、封装小巧,适合用于对精度与体积有平衡需求的电子产品。

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
