TZMB13-GS08 产品概述

一、产品简介

TZMB13-GS08 是 VISHAY(威世)出品的 13V 齐纳稳压二极管,采用 MiniMELF(SOD-80)表面贴装封装,额定耗散功率 500 mW,稳压值公差 ±2%。该器件为独立式齐纳配置,适用于小功率基准、稳压和过压保护等场合。MiniMELF 外形在狭小空间提供良好热路径和机械强度,适合自动化贴装与回流焊工艺。

二、主要参数

  • 名称:TZMB13-GS08
  • 品牌:VISHAY(威世)
  • 型号:13 V 齐纳二极管(标称)
  • 稳压值(标称):13 V
  • 稳压值(范围):12.74 V ~ 13.26 V(±2%)
  • 最大耗散功率 Pd:500 mW
  • 反向漏电流 Ir:100 nA(典型测试条件下)
  • 小信号阻抗 Zzt:26 Ω
  • 低电流阻抗 Zzk:110 Ω
  • 封装:MiniMELF(SOD-80),表面贴装

三、性能特点

  • 稳压精度高:标称 13 V,公差 ±2%,便于在需要固定基准电压的场合直接使用。
  • 低漏电流:反向电流小,适合高阻抗电路或低功耗应用。
  • 小信号阻抗低:在正常工作电流下 Zzt=26 Ω,电压随电流变化较小,稳压性能较好;在接近击穿膝点的低电流区阻抗较高(Zzk=110 Ω),应注意工作点选择。
  • 小型且结实:MiniMELF 封装提供良好热散和抗机械冲击性能,适合受限空间和可靠性要求较高的设计。
  • 易于批量贴装:兼容常见 SMD 流程和自动化元件装配。

四、典型应用

  • 低功率基准稳压(如为小信号放大器、传感器供参考电压)。
  • 过压/瞬态电保护(与限流元件配合使用)。
  • 电平移位、信号夹位和参考电压源。
  • 便携式和电池供电设备中的局部稳压或参考点。

五、使用建议与计算示例

  • 最大允许电流(短时间或持续)由 Pd 决定:Imax = Pd / Vz ≈ 500 mW / 13 V ≈ 38.5 mA。长期工作时应留有余量,避免接近极限功耗。
  • 在作为并联(分流)稳压器使用时,需用串联限流电阻 R 来分配电流:
    R = (Vin - Vz) / (Iz + Il)
    其中 Iz 为流过齐纳二极管的稳压电流,Il 为负载电流。
    示例:若 Vin = 18 V,目标稳压 13 V,负载电流 Il = 2 mA,选择 Iz = 5 mA(安全工作点),则 R = (18 - 13) / (5 mA + 2 mA) ≈ 714 Ω(常用取值 750 Ω)。
  • 为避免过热和不稳定,推荐工作电流远小于 Imax(例如 < 10~20 mA),并考虑环境温度与散热条件的影响。
  • 注意齐纳的阻抗随着电流变化而变化,低电流区域(接近击穿膝点)电压会有较大漂移,关键参考点应在 Zzt 指定的测试点附近工作以保证精度。

六、封装与安装注意事项

  • MiniMELF(SOD-80)为圆柱形小型 SMD 封装,良好热路径有利散热,但与平面封装相比需注意座位与焊盘匹配。
  • 推荐使用符合器件和PCB工艺的回流焊曲线进行焊接,具体焊接温度曲线请参照 VISHAY 官方资料或工艺规范。
  • 贴装方向通常无极性安装限制,但应按电路原理图正确识别各引脚与极性。
  • 储存与搬运要防潮、防静电,并避免机械冲击导致外壳损伤。

七、可靠性与采购建议

  • 在选型与批量采购前,应参考 VISHAY 原厂数据表以获取完整的绝对最大额定值、典型电气测试条件、温度特性和可靠性数据。
  • 对关键应用建议做实际样机测试,验证在目标电流、温度和负载变化下的电压稳定性与热性能。
  • 采购时确认包装形式(卷带/散装)、批次和合规性文件(如需要 RoHS/REACH 证明)以满足生产与合规需求。

八、结论

TZMB13-GS08 是一款适用于小功率稳压与保护用途的 13 V 齐纳二极管,具有±2% 稳压精度、低漏电流与 MiniMELF 封装的热机械优点。合理选择工作点并严格控制通过器件的电流与热耗散,可以在多种便携与工业电子场景中提供稳定可靠的基准电压或过压保护。购买与设计应用前建议查阅 VISHAY 官方完整数据手册以确认所有细节参数与工艺要求。

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.
