ZPD5.1 稳压二极管产品概述
一、产品概述
ZPD5.1 为 DIOTEC（德欧泰克）出品的独立式稳压二极管，封装为 DO-35 轴向玻璃/树脂封装，稳压值范围为 4.8V～5.4V，额定耗散功率 500mW。该器件适合用作低功耗电路中的基准稳压、过压钳位与小信号保护，结构简单、易于安装，适用于通用电子设备与工业应用。
二、主要电气参数
- 稳压范围（Vz）：4.8V ～ 5.4V（典型型号 ZPD5.1 标称 5.1V）
- 最大耗散功率（Pd）：500mW（在规定散热条件下）
- 动态阻抗（Zzt）：60Ω（影响稳压精度与纹波抑制）
- 反向漏电流（Ir）：100nA @ 800mV（漏电极低，有利于高阻应用）
- 工作结温范围：-50℃ ～ +175℃
三、性能特点
- 稳压精度适中，适合一般精度的基准源与保护电路。
- 低漏电流保证在微安级偏流下仍具稳定特性，利于电池供电或高阻态电路。
- 较大的结温范围与 500mW 功率等级，满足恶劣环境和较高温度下的长期工作。
- DO-35 封装便于手工焊接与通孔 PCB 组装，适合原型与低成本量产。
四、典型应用
- 稳压参考源：与限流电阻配合，为模拟电路或微控制器提供简单稳定的参考电压。
- 过压/浪涌钳位：保护输入端或敏感节点免受瞬态过压损坏。
- 电源去耦与噪声抑制：在要求不高的稳压场合可替代线性参考。
- 仪表与传感器系统中的低功耗基准。
五、使用注意事项与电路设计要点
- 限流电阻计算：R = (Vin − Vz) / Iz，注意 Iz 不应超过 Pd / Vz（以避免过功耗）。以 Vz ≈5.1V、Pd=500mW 估算最大稳态 Iz ≈98mA，应在实际电路中留裕量。
- 动态阻抗 60Ω 对负载变化和输入纹波有显著影响，需根据负载电流选择合适偏置电流以降低输出电压漂移。
- 在高温或靠近额定功耗工作时，注意散热与布局，减小结温升高以延长寿命。
- 对于精密基准用途，建议采用温度补偿或更低阻抗的稳压方案。
六、封装与采购信息
- 品牌：DIOTEC（德欧泰克）
- 型号：ZPD5.1
- 封装：DO-35（轴向）
- 适合通孔焊接，常见订购单位为卷带或散装。
七、可靠性与环境适应
ZPD5.1 设计满足宽温工作区（-50℃～+175℃），适合工业级与耐温需求较高的应用。长期可靠性与稳定性依赖于合理的功耗管理与良好 PCB 散热设计。

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.
