BZT52C15S 稳压二极管产品概述

一、产品简介

BZT52C15S 是创基(CBI)推出的一款独立式(离散)稳压二极管,封装为 SOD-323 表面贴装封装。该器件标称稳压值为 15V,稳压值范围为 13.8V ~ 15.6V,针对低功耗、小体积的基准电压、稳压保护和电压钳位等应用场景进行了优化设计。器件具有极小的反向漏电流和较低的工作功耗,适合对体积和成本有严格要求的电子产品。

二、电气特性要点

  • 标称稳压:15V(稳压值范围 13.8V ~ 15.6V)
  • 反向漏电流 Ir:100 nA(在 10.5V 条件下测得,表示在低电压/高阻抗电路中漏电极小)
  • 耗散功率 Pd:200 mW(器件在良好散热条件下的最大持续耗散功率)
  • 阻抗 Zzk:200 Ω(表示稳压二极管在低电流或“拐点”区域的等效阻抗)
  • 阻抗 Zzt:30 Ω(表示在测试电流下的动态稳压阻抗,稳压性能更佳)
  • 封装:SOD-323(小型表贴,适合高密度 PCB 布局)

以上参数适用于典型工作条件;实际设计时请参考厂家完整数据手册以获取测试电流、温度系数、极限参数等详细信息。

三、主要特点与优势

  • 小体积封装:SOD-323 适合微型化、空间受限的电路板设计,利于自动化贴装与回流焊工艺。
  • 低漏电流:100 nA 的反向漏电特性使其适用于高阻抗信号链、偏置电源和精密基准场合。
  • 合理的稳压精度范围:13.8V ~ 15.6V 的范围在多数 12V/15V 系统、保护电路中能够提供稳定的钳位与基准。
  • 可靠的稳压阻抗特性:在规定测试电流下 30 Ω 的动态阻抗能保证较稳定的输出电压变化控制。

四、典型应用场景

  • 低功耗电源轨的电压基准与微小负载稳压(例如小型传感器电路、便携设备的参考源)。
  • 过压钳位与浪涌保护,用于保护后端电路免受短时电压尖峰影响(适用于 12V 系统的局部保护)。
  • 信号钳位与波形整形:用于限制输入/输出信号幅值,保护敏感元件。
  • 偏置与参考电路:为放大器、比较器等提供稳定的偏置点(在允许的功率范围内)。

五、设计与使用建议

  • 功率与电流限值:根据耗散功率 Pd 计算最大允许稳流 Iz_max = Pd / Vz = 0.2 W / 15 V ≈ 13.3 mA。实际应用中建议留有余量,常用稳流范围选择在 0.5 mA ~ 5 mA 区间以延长器件寿命并降低温升。
  • 限流电阻:在作为稳压元件时,应在上游电源与二极管之间串接限流电阻 Rs = (Vin - Vz) / Iz。示例:若 Vin = 24V、Vz = 15V、Iz = 5 mA,则 Rs = 9 V / 5 mA = 1.8 kΩ;二极管耗散功率 Pd_diode = Vz * Iz = 75 mW,限流电阻耗散为 (Vin - Vz) * Iz = 45 mW。
  • 热管理:SOD-323 封装散热能力有限,长期大电流工作或高环境温度下需考虑降额使用和PCB散热(扩大铜箔面积、接地平面等)。
  • 过冲与浪涌保护:避免承受超出瞬态极限的浪涌电流,必要时与瞬态抑制器(TVS)或串联元件配合使用。
  • 工艺兼容:兼容主流回流焊工艺,贴片、回流参数请参照厂家推荐的工艺文件以避免过热损伤。

六、选型与采购信息

  • 型号:BZT52C15S
  • 品牌:CBI(创基)
  • 封装:SOD-323 在批量采购或用于关键产品前,建议向供应商索取并审核最新数据手册、可靠性报告及包装信息,确认环境温度、回流焊曲线和湿敏等级(若有)等要求。

若需更详细的电气曲线(击穿曲线、温度系数、测试电流条件)、外形尺寸或替代型号对比,我可以根据具体应用场景提供进一步的选型与电路设计建议。

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
