BZV55C6V2 产品概述

一、产品简介

BZV55C6V2 是一款小功率独立式稳压二极管(Zener),由品牌 YONGYUTAI(永裕泰) 提供,封装为 LL-34。器件在反向工作时呈现稳压特性,可作为基准电压源或过压箝位元件使用。标称稳压值为 6.2V,实际稳压范围为 5.8V~6.6V,适用于对电压精度要求中等、功耗较低的电路场合。

二、主要电气参数

  • 稳压值(标称):6.2V
  • 稳压值(范围):5.8V ~ 6.6V
  • 最大耗散功率 Pd:500 mW(环境温度和散热条件允许下)
  • 反向电流 Ir:2 μA @ 2V
  • 阻抗 Zzk:200 Ω(低电流或拐点区动态阻抗较大)
  • 阻抗 Zzt:10 Ω(在规定测试电流下的稳态动态阻抗)
  • 二极管配置:独立式(单个器件)
  • 封装:LL-34(SOD/DO-35 类似的小直插/贴片形式)

备注:在满载耗散功率下的连续最大反向电流可由 Pd / Vz 粗略估算,约为 80 mA;但实际使用应考虑散热与安全裕度并作降额处理。

三、典型应用场景

  • 低功耗基准电压源:为模拟前端或电平检测电路提供 6.2V 基准,配合限流电阻可构成简单稳压源。
  • 过压保护与钳位:保护对 6V 附近敏感的输入端、接口或参考节点,抑制瞬态过高电压。
  • 电源监控与参考:在电池、便携设备或单片机外围电路中用于参考/比较电压源。
  • 测试与教育电路:因封装小巧、易于焊接,常用于实验或样机验证。

四、使用注意事项与设计建议

  • 热管理:500 mW 为器件在良好散热条件下的最大耗散。若在封闭空间或高环境温度下使用,应适当降低工作电流或增加 PCB 铜箔作为散热片。
  • 电流选配:为获得稳定稳压及较低噪声,常建议工作电流选在毫安级(如 1–20 mA)范围;避免长期在最大耗散电流附近工作。
  • 动态阻抗影响:Zzk=200Ω 表明在低电流区电压随电流变化较敏感,若需要更精确电压,建议提高工作电流至使动态阻抗接近 Zzt(10Ω)对应的测试点。
  • 反向泄漏:Ir=2 μA @2V 指示在低电压偏置下漏电较小,但在高温下漏电会增加,需在高温设计中预留裕度。
  • 并联/串联:不建议直接并联多个稳压二极管以提高功率,若必须并联需确保各支路电流均衡。

五、封装与机械信息

LL-34 封装体积小,适合通过孔安装或小面积贴装。安装时注意焊接温度与时间,避免过热影响器件可靠性。机械尺寸及引脚标识以厂商出货说明为准。

六、选型与质量建议

  • 若需要更高精度或更低动态阻抗,可考虑选择更高功率或有先验测试电流下标注低 Zzt 的型号。
  • 采购时确认批次一致性,建议向供应商索取详细原厂规格书(Datasheet)及可靠性报告以便在关键应用中验证。

总结:BZV55C6V2 提供了体积小、用于 6.2V 级别的经济型稳压解决方案,适合一般的基准、保护与监控用途。在设计时应关注散热与工作电流分配,以保证长期稳定与可靠性。

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
