ZY7.5 稳压二极管产品概述
一、产品简介
ZY7.5 是 DIOTEC（德欧泰克）生产的独立式稳压二极管，典型稳压值位于 7.0V 至 7.9V 范围内。封装为常见的 DO‑41 直插玻璃／环氧封装，额定耗散功率 Pd=2W，适用于中低功率稳压与浪涌钳制场合。工作结温范围宽（-50℃ ～ +150℃），在工业级温度条件下仍能保持稳定性能。
二、主要电气参数
- 稳压范围：7.0V ～ 7.9V（标称 Zener 电压 7.5V）
- 反向电流 Ir：1 μA @ 2V（表示在较低反向电压下漏电小）
- 阻抗 Zzt：2 Ω（在指定测试电流下的小信号阻抗，代表稳压能力好）
- 最大耗散功率 Pd：2 W（需在良好散热条件下使用）
- 工作结温：-50℃ ～ +150℃
- 封装：DO‑41（轴向直插，便于手工与波峰/选择性回流焊接）
三、性能特点与优势
- 稳压精度高且阻抗低，适合需要较稳定基准电压或过压保护的应用。
- 低反向漏电在微功耗电路中尤为重要，可降低静态功耗。
- 宽温度范围与较高结温上限，适合工业/户外等恶劣环境。
- DO‑41 封装便于散热与机械安装，且适配传统 PCB 布局与插件工艺。
四、典型应用场景
- 参考电压源与基准电路（当要求 7.5V 左右稳压时）
- 电源防护与浪涌钳制（对瞬态过压进行限制）
- 工业控制器与仪表的局部稳压或保护电路
- 电池供电系统中的电压监测与防反接保护
五、使用与散热注意事项
- 耗散功率为 2W 为器件在理想散热条件下的最大值，实际使用时需计算功耗 Pd = Vr × Iz（Vr 为稳压电压偏差下的电压，Iz 为稳流电流）。当功耗接近最大值时应增加散热（例如加热 sink、使用散热良好的 PCB 区域或减少工作电流）。
- 在高环境温度与高电流情况下，结温容易升高，应确保结温不超过 +150℃ 的上限。
- 避免长期在极限额定条件下工作，以延长可靠性并减少参数漂移。
六、封装与焊接建议
- DO‑41 为轴向引线封装，适合插件焊接及自动插件装配。焊接时应控制回流/波峰温度与时间，避免超温导致封装老化或参数变化。
- 推荐在 PCB 上留有充足铜面积以利于散热，直插引脚处可增加铜箔或接地铜层作为散热路径。
七、可靠性与选型建议
- 若应用需要更高功率余量或更严格的温度稳定性，可选用功耗更高或封装带散热片的稳压器件；如需更精确的参考电压，建议采用专用基准源。
- 同一系列中可比较 Zy7.5 与邻近电压型号以确定最佳匹配；选型时同时考虑最大浪涌电流、测试条件下的 Zzt 与温度系数。

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.
