ZMD13 产品概述

一、产品简介

ZMD13 是 DIOTEC(德欧泰克)推出的一款独立式稳压二极管,面向要求稳定电压基准与过压钳位的小功率应用场景。该器件在 DO-213AA 封装中提供可靠的稳压特性,工作结温范围宽 (-50 ℃ 至 +175 ℃),适应恶劣环境和工业级温度要求。产品常被用于低功耗电子设备、传感器前端、通信终端与汽车电子的辅助稳压与浪涌保护电路中。

二、主要电气参数

  • 稳压范围:12.4 V ~ 14.1 V(工作/稳压电压区间)
  • 反向电流 Ir:500 nA @ 9 V(低漏电流,有利于高阻电路)
  • 耗散功率 Pd:1 W(器件最大耗散功率,需在使用时考虑散热)
  • 阻抗 Zzt:25 Ω(动态阻抗,反映稳压精度与纹波抑制能力)
  • 二极管配置:独立式(单体稳压二极管)
  • 工作结温范围:-50 ℃ ~ +175 ℃
  • 品牌/封装:DIOTEC(德欧泰克),DO-213AA 封装
    这些参数共同决定了 ZMD13 在中低功率稳压与钳位场合的表现:稳压电压适中、漏电流极小、动态阻抗适合一般模拟与供电滤波需求。

三、典型应用场景

  • 参考电压源与基准:向 A/D、比较器等提供稳定基准电压(配合阻容滤波以降低噪声)。
  • 保护电路:作为过压钳位元件保护下游电路免受瞬态过压影响。
  • 电源辅助稳压:在低功耗模块或次级电源中作为简易稳压手段(需配串联限流元件)。
  • 工业与汽车电子:宽温特性使其适用于工业控制器、传感器节点与车载电子的局部稳压或浪涌吸收。

四、热与可靠性考虑

ZMD13 的最大耗散功率为 1 W。近似计算器件在稳压电压附近的最大持续电流:

  • Iz_max ≈ Pd / Vz ≈ 1 W / 13 V ≈ 77 mA(理论上限),实际使用应考虑散热与安全裕量。
    建议长期工作电流按 Pd 的 40%60% 进行降额设计(即持续电流建议控制在 3045 mA 范围内),并保证良好散热路径与合适的 PCB 散热面积以避免结温超过额定值。结温管理直接影响漏电流、稳压精度与器件寿命。

五、封装与安装

DO-213AA 封装尺寸小巧,便于在空间受限的设计中使用。器件为独立式元件,建议按制造商给出的封装图及推荐焊盘布局进行 PCB 布局。焊接时注意温度曲线以保护器件性能,并在可能的高温或振动环境中采取机械固定措施。

六、选型与使用建议

  • 如果系统对静态功耗敏感,ZMD13 的低反向漏电(500 nA @9 V)是重要优势。
  • 计算串联限流电阻 R:R = (Vin - Vz) / Iz ;实际选择 Iz 时应考虑稳态与瞬态条件以及器件阻抗(Zzt ≈ 25 Ω)对稳压的影响。
  • 对于纹波较大或负载变化显著的场合,需增大滤波电容或选用动态阻抗更低的稳压源以提高稳压精度。
  • 在高温或高功率条件下,应进行热仿真或测试以验证结温,必要时采用降额或增加散热措施。

七、结论

ZMD13 是一款性能均衡、适用于多种工业与民用场合的 12.4 V~14.1 V 稳压二极管。凭借 1 W 的功耗能力、25 Ω 的动态阻抗、极低的漏电流及宽温范围,它在局部稳压、基准源与过压保护方面表现可靠。选择时应结合系统输入电压、负载电流、允许温升与散热条件进行合理匹配,以确保长期稳定运行。型号:ZMD13,品牌:DIOTEC(德欧泰克),封装:DO-213AA。

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.
