BZV55C15 稳压二极管（15V，LL-34）产品概述
一、产品简介
BZV55C15 为 YONGYUTAI（永裕泰）生产的独立式稳压二极管，额定稳压值标称 15V，实际批次稳压范围 13.8V～15.6V。采用轴向玻璃封装 LL-34，单颗独立元件，适用于低功耗、小体积的参考电压与过压保护场合。器件耗散功率 Pd 为 500mW，适合做小电流分流稳压或基准源。
二、主要电气参数
- 标称稳压值：15V（规格范围 13.8V～15.6V）
- 反向漏电流 Ir：规格表标注 100 nA @ 11V（注：不同资料中对 11V 条件下漏电值有差异，另有测量值 2 µA@11V，应以出厂检验数据为准）
- 耗散功率 Pd：500 mW（室温、自由对流条件下）
- 低频阻抗 Zzt：30 Ω（在规定测试电流下）
- 拐点阻抗 Zzk：110 Ω（在拐点测试电流下）
- 封装：LL-34（轴向玻璃）
三、典型应用场景
- 小信号电路的稳定参考电压源
- 低功耗传感器和便携设备的分流稳压
- 信号钳位、波形剪裁与低能量浪涌抑制
- 精密模拟电路中的简单温度补偿与参考
四、设计与使用建议
- 功率与散热：器件最大耗散 500 mW，应在实际电路中留有安全余量。建议在长期工作时将最大耗散限制在额定值的 50% 左右以提高可靠性。
- 偏置电流选择：稳压二极管在不同偏流下稳压精度与动态阻抗不同。选用合适的偏置电流（例如参考值 1–10 mA，视电路要求）以保证稳压性能，同时计算二极管功耗 Pd ≈ Vz × Iz。
- 设计电阻示例：若 Vin=20V，目标 Vz≈15V，假定选择偏置 Iz=5 mA 并且负载电流 Il=2 mA，则串联限流电阻 R = (20−15)/(Iz+Il) ≈ 714 Ω；二极管耗散约 15V×5mA = 75 mW。
- 动态阻抗：Zzt=30 Ω 表明在测试电流下稳压源的交流阻抗较低；Zzk=110 Ω 表明在拐点附近伏安陡峭度下降，避免长期工作在拐点电流附近以免稳压不稳。
五、封装与可靠性
LL-34 为轴向玻璃封装，体积小、引脚耐焊性好，适用于通孔安装。焊接时请遵守厂家推荐的温度和时长，避免高温对封装与封装胶的损伤。储存与装配时注意防潮、防机械应力，防止引脚弯折或玻璃破裂影响性能。
六、选型与替代
BZV55C15 适合作为 15V 级别的小功率稳压/参考元件。若需更高功率或更低噪声、更精确稳压，请考虑功耗更大的稳压管或专用参考源。选型时应对照 Ir、Zzt、Zzk 及稳压范围等参数，优先参考厂商完整的规格书与出厂测试报告。
使用本器件时，请以 YONGYUTAI 提供的最新规格书为准，必要时做样品测试以验证在目标工作点下的稳压精度与长期稳定性。

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.
