BZX84C6V2(Hottech 合科泰)—— 6.2V 350mW SOT-23 稳压二极管产品概述

一、产品概况

BZX84C6V2 为 Hottech(合科泰)系列小功率稳压二极管,标称稳压值 6.2V,封装为 SOT-23,单个独立二极管结构,适合对电压有简单截断或稳压要求的小型电子设备。器件在反向击穿区工作,在稳压区能保持近似恒定电压,以保护或提供参考电压源。

二、主要电气参数

  • 标称稳压值(Vz):6.2V(允许范围 5.8V ~ 6.6V)
  • 最大耗散功率(Pd):350mW(结温及环境需按厂商建议进行降额使用)
  • 反向电流(Ir):3 µA(在规定的反向电压条件下)
  • 稳压阻抗:Zzt = 20 Ω(动态阻抗)
  • 膝部阻抗:Zzk = 150 Ω(在击穿曲线膝部区域)
  • 工作结温范围:-65 ℃ ~ +150 ℃
    这些参数决定了器件在不同偏流、温度与电压条件下的稳压精度、噪声及热性能。

三、性能与特点

  • 小封装、体积小、适合高密度 PCB 布局(SOT-23)
  • 中等精度稳压:6.2V 标称值,在指定范围内波动(5.8–6.6V)
  • 低静态反向电流:3 µA,适合低泄漏要求的电路
  • 中等动态阻抗(20 Ω),在中等工作电流下具有较好的电压保持能力
  • 允许的耗散功率 350mW,适合小功率稳压或过压保护应用

四、设计应用与使用注意

  • 常见应用:电压钳位/过压保护、小电流基准、低功耗测控电路、接口保护等。
  • 电源电路设计:通常通过串联限流电阻将多余电压由二极管耗散。稳压二极管功率为 Pd = Vz × Iz(在稳压状态下),因此最大稳压电流 Iz(max) ≈ 350mW / 6.2V ≈ 56 mA(理论值,应考虑温度降额和安全裕量)。建议在实际设计中采用远低于此值的工作电流并留有裕量。
  • 热管理:SOT-23 包装散热能力有限,实际功耗受 PCB 铜箔面积和环境影响较大。建议在高功率或连续稳压场合增加散热铜箔并进行功耗降额。
  • 噪声与精密要求:小功率 Zener 噪声和温漂相对较大,如需高精度低漂移电压基准,应采用专用参考源芯片。

五、封装与安装建议

  • SOT-23 封装有利于表面贴装自动化生产与体积优化。布线时尽量在二极管附近增加散热铜箔或过孔以提高热传导。
  • 引脚说明与焊接工艺请参照厂商封装图纸,控制回流温度曲线以避免对结温造成损伤。

六、可靠性与存储

  • 工作温度范围宽(-65 ℃ 至 +150 ℃),适应工业级温度要求,但长期可靠性取决于结温及功耗管理。
  • 存储和贴片前请保持干燥包装或遵循厂商的防潮储存规范,避免吸湿导致回流焊时封装缺陷。

七、选型与采购建议

  • 若需要与 BZX84 系列其它稳压值互换,注意稳压偏差和动态阻抗差异。
  • 采购时确认厂商型号与批次,必要时索取完整数据手册以核实测试条件(测试电流、测量条件等),并按实际应用对器件进行热仿真与实验验证。

总之,BZX84C6V2(Hottech 合科泰)为一款适合小功率稳压与过压保护的 SOT-23 封装稳压二极管。在电流与功率设计、散热布局和对稳压精度要求的权衡下,可在消费电子、工业接口保护及低功耗电路中发挥良好作用。

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.
