SMZ100 稳压二极管 产品概述

一、主要参数

  • 型号:SMZ100(DIOTEC/德欧泰克)
  • 二极管配置:独立式稳压二极管(单只器件)
  • 稳压值(范围):94V ~ 106V(标称约100V,容差 ±5%)
  • 反向电流 Ir:1 μA @ 50V(注:反向漏电流随电压和温度升高而增加)
  • 阻抗 Zzt:200 Ω(在规定测试条件下的小信号动态阻抗)
  • 耗散功率 Pd:2 W(器件在规定环境与散热条件下的最大耗散功率)
  • 封装:DO-213AB

二、产品特点

  • 高电压定位:面向约100V级别的电压基准与保护场合,适合需要稳定高压参考或限压的电路。
  • 低漏电:在50V条件下反向漏电仅1 μA,可在一些对漏电敏感的高压应用中降低误差与能耗。
  • 良好稳压能力:Zzt = 200 Ω 表示在小幅电流变化下仍能维持较稳定的稳压输出,配合合适工作电流可获得满意的电压精度。
  • 工业封装:DO-213AB 提供便于安装和较好机械强度的封装形式,适合手工或自动化焊接工艺。

三、电气与热特性说明

  • 最大稳压电流(近似):在理想散热条件下,最大恒定电流可由 Iz_max ≈ Pd / Vz 估算。以 Vz ≈ 100V、Pd = 2W 计算,Iz_max ≈ 20 mA。实际应用中应考虑环境温度、散热条件及安全裕量,通常采用远低于该值的工作电流以延长寿命并保证温升。
  • 动态响应:稳压电压随电流变化大约 ΔV ≈ Zzt × ΔI。Zzt = 200 Ω 意味着电流每变化1 mA,稳压电压约变化0.2 V。设计时需将此项纳入误差预算。
  • 漏电与温度:给出的 Ir 测试点为 50V,器件在接近其稳压电压和高温条件下的漏电会显著增大,影响微安级电流电路的精度。

四、典型应用

  • 高压参考源:作为模拟电路、高压采样电路中的参考电压或偏置源。
  • 高压限幅/保护:用于防止电压超过约100V 的浪涌或过压,保护下游器件(需配合限流元件)。
  • 试验/测量系统:高压测试设备中的稳定点供电或参考基准。
  • 电子负载与偏置:在需要恒定高压偏置的小电流场合使用。

五、使用建议与注意事项

  • 严格限制功耗:设计时应确保器件耗散功率不超过 Pd,并预留温升裕量;在较高环境温度或通风不良的条件下应降低工作电流或增加散热措施。
  • 选择工作电流:为兼顾稳压精度与热裕量,建议工作电流在几毫安到十毫安量级,示例:Iz = 10 mA 时,P ≈ 100V × 10 mA = 1 W(仍需考虑封装散热能力)。
  • 保护电路:在有浪涌或脉冲高压的场合,需加入限流电阻、热熔保险或瞬态抑制元件以防止短时峰值损坏。
  • 考虑容差与温漂:±5% 的稳压容差及随温度变化的特性需在系统误差预算中体现;必要时可采用温度补偿或外部误差放大电路。
  • 测试与选型:在最终产品中请基于实际工作电压、电流和温度对样品做可靠性与稳压性能测试,确认满足系统需求。

以上为 SMZ100 的产品概述。若需电路示例、详细热阻数据或特定工作点下的伏安特性曲线,可进一步提供应用场景与工作条件,我将据此给出针对性的设计建议。

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
