ZMY30 稳压二极管产品概述
一、产品简介
ZMY30 是 DIOTEC（德欧泰克）推出的一款30V标称稳压二极管，封装为 DO-213AB。该器件设计用于作稳压基准和稳压保护，具有低反向漏电、高稳压精度以及良好的热稳定性，适合多种电源管理与保护场景。
二、主要电气参数
- 稳压值（标称）：30V，允许范围28V～32V，可满足中高压稳压需求。
- 反向电流 Ir：1 μA @ 14V，漏电流极小，有利于提高静态功耗性能和系统精度。
- 阻抗 Zzt：8 Ω（动态阻抗），代表在规定测试电流下的等效交流阻抗，阻抗较低，负载变化时稳压性能良好。
- 耗散功率 Pd：1.3W，为器件最大允许耗散功率，须结合热设计进行使用。
三、热性能与可靠性
工作结温范围为 -50 ℃ 至 +150 ℃，能够在宽温度范围内保持性能稳定。需要注意的是 1.3W 的耗散功率通常基于理想散热条件给出，实际电路中应考虑散热路径与环境温度，对功耗进行适当降额。例如在不良散热情况下应限制流经二极管的电流，以避免结温超过允许范围影响寿命。
四、使用与计算建议
作为并联稳压元件时，可用公式 Imax ≈ Pd / Vz 估算理论最大电流：1.3W / 30V ≈ 43 mA。但实际应用中建议留有余量（典型建议 50%～75% 降额），并配合限流电阻或恒流源使用，保证长期可靠性。动态阻抗 8 Ω 表明当负载电流发生变化时，伏特变动量约为 ΔV ≈ Zzt × ΔI，应据此评估输出纹波与稳压精度。
五、封装与装配
DO-213AB 为轴向引线封装，适合通孔焊接和波峰/手工焊接工艺。在焊接时建议控制焊接温度与时间，避免对器件本体造成过热；存储和装配过程中应注意防潮防静电，保证焊点机械与电气连接可靠。
六、典型应用场景
- 基准稳压：为模拟与数字电路提供稳定参考电压。
- 过压/浪涌保护：在电源瞬态情况下作为钳位元件，保护后级电路。
- 通用电源模块：用于小功率电源的二级稳压或分压补偿。
七、选型与注意事项
选择 ZMY30 时应核实系统最大允许电流、环境温度及散热条件；若负载电流较大或环境温度高，建议选用功耗更高或带散热片的替代型号。使用中需关注工作电压是否长期处于稳压二极管的高应力区，并留意反向漏电对低功耗电路的影响。
如需更详细的电气特性曲线、测试条件或封装图纸，可参考厂商数据手册以完成最终设计确认。

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.
