BZT52C16 稳压二极管 产品概述

一、产品简介

BZT52C16 是一款独立式硅稳压二极管,标称稳压值为 16V,适用于低功率稳压与电压钳位场合。该型号由 Slkor(萨科微)提供,封装为 SOD-123,单只耗散功率为 500mW,结构紧凑,便于表面贴装和批量生产使用。

二、主要参数与特性

  • 稳压值(标称):16V
  • 稳压值范围:15.3V ~ 17.1V
  • 反向电流(Ir):100nA(典型小泄漏电流,有利于高阻电路)
  • 耗散功率(Pd):500mW(建议工作电流与功耗在安全余量内)
  • 阻抗(Zzt):40Ω(表示在规定测试电流下的动态阻抗)
  • 工作结温范围:-65℃ ~ +150℃
  • 封装:SOD-123,表面贴装小型封装,适合空间受限设计

注:提供信息中有一条“[email protected]”的描述与本型号 16V 的标称值存在不一致,建议在采购或设计前向供应商确认测量条件或是否为其他变体。

三、电气特性及设计注意事项

稳压二极管作为并联稳压元件使用时,需要与限流电阻配合计算工作电流与功耗。理论上最大稳压电流 Iz(max) ≈ Pd / Vz,即 0.5W / 16V ≈ 31mA,但实际应考虑温升与安全余量,常规设计中建议把直流工作电流控制在几毫安到十毫安量级(例如 5~15mA),以延长器件寿命并减少温度漂移。动态阻抗 Zzt=40Ω 表明在小信号变化下稳压能力有限,若要求精确参考电压,应考虑更低阻抗或配合后端放大电路。

反向电流 Ir=100nA 为静态泄漏,可在高阻输入或电池监测电路中带来极小误差,但在超低电流测量场合仍需注意。

四、典型应用场景

  • 低功耗电源的次级稳压或参考电压源
  • 信号线过压钳位、浪涌保护(需与限流元件配合)
  • 仪表、传感器接口的电压参考或保护元件
  • 通信设备、电池管理、电源模块等对空间和成本敏感的场合

五、封装与安装注意事项

SOD-123 为小型表贴封装,焊接时应注意:

  • 控制回流焊温度曲线,避免超过结温上限并减少热应力;
  • 焊盘设计参照厂商推荐,以确保良好热散与可靠焊接;
  • 对于长期高功耗工况,应保证良好散热或降低稳流电流以防过热。

六、可靠性与环境适应

工作结温范围宽 (-65℃ ~ +150℃),适应工业温度级别。为保证长期可靠性,建议在设计中为器件留有功率余量,避免长期在靠近 Pd 极限运行,并做好电压和浪涌保护。ESD 与浪涌耐受能力按器件规格执行,关键应用建议增加保护元件或滤波以提高系统可靠性。

七、选型建议与替代方案

在需要更低噪声、更小阻抗或更高精度参考时,可考虑专用基准源或低阻抗稳压二极管。若系统工作电流更大或需要更高功耗承受能力,应选择更高 Pd 的稳压二极管或使用稳压芯片。采购时请核对制造商数据表、测试条件与批次标识,确认“[email protected]”类不一致信息,以避免选型错误。

如需具体电路示例、限流电阻计算或热设计指导,可提供电源输入电压、期望稳压电流与工作环境温度,便于给出更精确的设计建议。

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
