ZMY68 产品概述 — DIOTEC 稳压二极管(DO-213AB)

一、产品简介

ZMY68 为 DIOTEC(德欧泰克)出品的一款独立式稳压二极管,稳压值范围为 64V~72V(典型值 68V),适用于要求中高压、稳定电压参考或钳位保护的应用场景。器件为单体配置(独立式),小型封装 DO-213AB,设计用于在宽温度范围内可靠工作,适合工业级电路设计。

二、关键参数(概要)

  • 稳压值范围:64V ~ 72V(型号名 ZMY68 对应典型稳压点 68V)
  • 反向电流 Ir:1 μA @ 34V(低漏电特性,有利于高阻电路的稳定性)
  • 耗散功率 Pd:1.3 W(在推荐散热条件下的最大耗散)
  • 阻抗 Zzt:80 Ω(小信号阻抗,影响动态调节与噪声)
  • 工作结温范围:-50 ℃ ~ +150 ℃
  • 封装:DO-213AB(小型塑封,便于电路板安装与焊接)
  • 配置:独立式(二极管单体)

三、主要特性与优势

  • 高电压稳压:64–72V 范围满足高压参考与吸收场合需求;
  • 低反向漏电:在 34V 条件下 Ir 仅 1 μA,有利于低功耗系统与高阻抗测量;
  • 宽温度范围:-50 ℃ 至 +150 ℃,适合严苛环境与工业级应用;
  • 合理功耗与封装:1.3W 耗散在 DO-213AB 小封装下实现,适配一般 PCB 散热设计;
  • 明确的小信号阻抗(Zzt=80Ω),便于在噪声与动态响应设计中评估性能。

四、典型应用场景

  • 高压参考源:作为基准稳压元件提供稳定电压参考;
  • 过压钳位与保护:用于电子电源或输入端的过压吸收与保护电路;
  • 稳压子电路:结合限流电阻构成简单稳压模块,为后级电路提供保护与偏置;
  • 工业及汽车电子:在高温、宽频环境下提供可靠性能(需留意环境与封装散热)。

五、使用建议与注意事项

  • 电流限制:使用时应通过串联限流电阻或恒流源限定工作电流,避免超过 Pd 导致过热;
  • 散热处理:1.3W 为器件在参考散热条件下的额定耗散,实际应用需通过 PCB 铜箔、散热垫或足够焊盘面积进行热管理;
  • 动态性能:Zzt=80Ω 表明在快速电流变化时稳压点存在一定动态阻抗,若需低噪音、低阻抗源,应考虑并联低阻抗滤波或选择更低 Zzt 的型号;
  • 环境与寿命:在高温或频繁温度循环场合应适当降额使用(例如降低工作电流或增加散热),以延长可靠性;
  • 引脚与安装:DO-213AB 封装便于焊接,但应避免过热回流时间过长,遵循制造商焊接曲线。

六、典型接法(概要)

常见用法为二极管反向工作,在输入电压高于稳压值时通过串联电阻限制电流,使二极管在稳压区工作,为后端电路提供稳定参考或完成钳位保护。示意:Vin — R限流 —|<— Vout(稳压二极管反向并联至地)。

七、选型与替代

选择 ZMY68 时,重点核对稳压电压范围、最大耗散、温度等级与封装适配性。若需要更低阻抗或更高功率,应考虑功率更大或 Zzt 更低的稳压管;若需更精确的稳压点,可选择具有更窄容差的参考源。

八、包装与采购

品牌:DIOTEC(德欧泰克);封装:DO-213AB;常见按卷装或单件包装供应,采购时请确认最小订购量与包装形式,并参考供应商提供的器件数据手册以获取完整电气和机械规范。

如需我根据具体电路(工作电压、工作电流、环境温度及 PCB 散热条件)给出限流电阻计算、功耗评估与布局建议,可提供参数,我将给出详细设计建议。

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.

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
