BZV55C7V5 产品概述
一、概述
BZV55C7V5 为独立式稳压二极管（稳压齐纳管），标称稳压值 7.5V，稳压范围 7.0V～7.9V，额定耗散功率 500mW，适用于低功耗、小型化电源稳压与基准电路。品牌：YONGYUTAI（永裕泰）；封装：LL-34（小型直插封装），便于通孔安装和手工焊接。
二、主要电气参数
- 标称稳压：7.5V（范围 7.0V～7.9V）
- 最大耗散功率 Pd：500mW（须良好散热与降额使用）
- 稳压阻抗：Zzk 50Ω，Zzt 7Ω（依据测试电流不同，参数用于评估稳压性能）
- 反向漏电流 Ir：100nA @ 5V（典型）；资料中亦见 2µA @ 5V 的测试值，实际以出厂数据手册为准
三、特点与优势
- 小体积封装（LL-34），适合空间受限的电路板布局
- 低至中等耗散能力（500mW），适合小信号稳压、基准和偏置电路
- 相对较低的稳压阻抗（Zzt）有利于在规定电流下保持较稳定的稳压值
- 品牌与封装适合中低成本批量应用及维修替换
四、典型应用
- 低功耗基准电压源与偏置电路
- 信号线电压钳位、保护过压（低能量脉冲）
- 小型传感器供电或检测试电路的参考稳压
- 教学、实验与原型开发中的通用稳压元件
五、使用与注意事项
- 耗散功率有限：工作时应保证热阻小、合理降额（建议在环境温度和散热条件下计算允许最大电流）。
- 需串联限流电阻以防止过流：R ≥ (Vin_max - 7.5V) / Iz_allow，其中 Iz_allow 由 Pd 限制计算得到。
- 反向漏电流与稳压特性受温度影响明显，高温下漏电与稳压偏移增加，应在电路设计中考虑温漂。
- 不适用于高能量瞬态抑制或高功率恒流稳压场合。
六、选型与替代
在选型时应核对供应商完整数据表，确认测试电流条件下的稳压值与阻抗。对功率有更高要求时，可选择更大耗散能力或采用封装带散热面的器件；对稳压精度要求高的场合建议使用精密基准源替代。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
