ZMY20 稳压二极管(DIOTEC)

一、产品概述

ZMY20 是 DIOTEC(德欧泰克)出品的一款独立式稳压二极管,设计用于中低功率的稳压与参考场合。稳压值在 18.8V ~ 21.2V 范围内,典型应用包括电源辅助稳压、基准电压源、低功耗保护电路及各种电子测量与控制模块。器件采用 DO-213AB 封装,结构紧凑,适合工业级环境使用。

主要电气与热特性(典型/额定值):

  • 稳压范围:18.8V ~ 21.2V
  • 反向电流 Ir:1 μA @ 10 V
  • 耗散功率 Pd:1.3 W
  • 动态阻抗 Zzt:15 Ω(典型)
  • 工作结温范围:-50 ℃ ~ +150 ℃
  • 封装:DO-213AB
  • 品牌:DIOTEC(德欧泰克)

二、主要特点与优势

  • 高稳定性:稳压电压在 18.8V~21.2V 范围内,适合需要 20V 级参考/稳压的场合。
  • 低漏电流:1 μA@10V 的低反向电流有利于降低静态功耗并提高精度,适合计量与仪表应用。
  • 中等功耗能力:1.3W 的耗散功率满足多数低功耗稳压设计,常配合限流电阻使用。
  • 宽温度范围:-50℃ 至 +150℃ 的结温范围适合恶劣环境和工业级应用。
  • 可靠封装:DO-213AB 封装方便 PCB 安装与散热控制,便于量产装配。

三、典型应用场景

  • 简单的线性并联稳压(分流稳压)电路,为小型电子设备提供 20V 左右的参考电压。
  • 传感器供电与基准电压源——低漏电特性提高测量稳定性。
  • 过压保护与浪涌吸收电路(在合适的限流条件下)。
  • 工业控制、通信设备和便携测量仪器中的辅助电源模块。

四、设计与使用建议

  • 稳压器工作为并联(分流)类型时,需用串联限流电阻 Rs 来设定稳压电流 Iz:R = (Vin - Vz) / Iz。
    例:若 Vz ≈ 20V,输入 Vin = 30V,期望稳定电流 Iz = 10 mA,则 R = (30-20)/0.01 = 1 kΩ。
    同时需保证 Pd = Vz × Iz ≤ 1.3 W(上例 Pd = 0.2 W,安全)。
  • 允许的最大稳流 Iz_max 可由 Pd / Vz 估算(Iz_max ≈ 1.3W / ~20V ≈ 65 mA),但实际设计应留有余量并考虑结温与散热状况。
  • 动态阻抗 Zzt = 15 Ω 表征了在工作点附近电压随电流变化的敏感度,若对输出电压精度要求高,应在稳压点维持足够的分流电流以降低等效误差。
  • 高温下漏电流会增加,应在高温工况做温漂校核,必要时采用温度补偿或选用更低温漂的方案。

五、封装与可靠性注意事项

  • 封装:DO-213AB。具体外形尺寸、引脚标识与焊接要求请参见厂方数据手册。
  • 焊接与热处理:遵循制造商推荐的回流/波峰焊工艺与温度曲线,避免超过器件允许的最高结温。
  • 存储与静电防护:建议在干燥、防静电环境中存放,装配时采取 ESD 防护措施,避免静电损坏。

六、选型与采购提示

  • 在确定器件之前,请核对目标应用的最大反向电压、工作电流以及允许功耗,优先参考芯片完整数据手册中的典型曲线与耐受极限。
  • 如需更高精度或更大功率,请与厂方或代理商咨询相近系列产品或封装方案。

ZMY20 以其稳定的 20V 级稳压特性、低漏电和工业级的工作温度范围,适合对成本、可靠性与环境适应性有要求的中低功率稳压应用。欲获取更详细的电气特性曲线、热阻与机械尺寸图,请查阅 DIOTEC 官方数据手册或联系供应商技术支持。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
