LM3Z33VT1G 稳压二极管产品概述

LM3Z33VT1G是乐山无线电股份有限公司(LRC)推出的独立式稳压二极管,针对小功率电路的电压基准、过压保护及低功耗稳压场景优化设计,核心参数兼顾宽温适应性、低漏电流与稳定阻抗特性,适合高密度表面贴装应用。

一、核心参数与性能解析

该器件的关键参数明确了其应用边界与性能优势:

  • 稳压特性:标称稳压值33V,工作范围31V~35V,覆盖不同应用对稳压精度的差异化需求;动态阻抗Zzt=80Ω(典型测试条件下),Zzk=300Ω,低阻抗意味着输出电压波动极小,稳压性能稳定可靠;
  • 低功耗设计:反向漏电流仅50nA(@23.2V反向电压),静态功耗可忽略,适合电池供电等低功耗场景;最大耗散功率200mW,配合限流电阻可满足小电流(如≤6mA)电路的稳压需求;
  • 宽温适应性:工作结温范围-65℃+150℃,覆盖工业级(-40℃+85℃)及扩展温区,可稳定工作于户外、工业控制等严苛环境。

二、封装与可靠性设计

LM3Z33VT1G采用SOD-323封装(尺寸约1.6mm×0.8mm×0.6mm),属于超小型表面贴装封装,具有以下优势:

  • 高密度PCB适配:封装尺寸紧凑,可显著节省电路板空间,适合智能手机、智能穿戴、工业传感器等小型化产品;
  • 自动化生产兼容:表面贴装工艺与常规SMT设备兼容,便于批量生产,降低组装成本;
  • 可靠性保障:LRC成熟的封装工艺确保器件耐温、耐湿性能,宽结温范围进一步提升了极端环境下的使用寿命。

三、典型应用场景

结合参数特性,LM3Z33VT1G可广泛应用于以下场景:

  1. 电压基准源:为运算放大器、ADC/DAC、比较器等电路提供稳定的33V参考电压,低漏电流不影响电路整体功耗,确保信号精度;
  2. 过压保护电路:并联于电源输出端,当电压超过稳压范围上限(35V)时,器件击穿并钳位电压,保护后级敏感器件(如MCU、传感器)免受过压损坏;
  3. 小功率稳压电路:配合1kΩ左右限流电阻,可将输入电压(如40V)稳压至33V,为低功耗模块(如无线通信模块、传感器节点)提供稳定供电;
  4. 宽温环境应用:工业现场的温度传感器、车载辅助电路(如仪表盘背光控制)等,可在-65℃~+150℃范围内稳定工作,无需额外温补偿。

四、品牌与品质保障

乐山无线电(LRC)是国内分立器件领域的龙头企业,LM3Z33VT1G属于其稳压管系列的成熟产品,具有以下品质优势:

  • 参数一致性:批量产品的稳压值离散性控制在±1V内(符合31V~35V范围),确保电路性能稳定;
  • 环保合规:符合RoHS、REACH等国际环保标准,无铅封装满足绿色制造需求;
  • 供货稳定:LRC具备完善的产能体系,可满足中小批量及大规模生产的供货需求。

总结而言,LM3Z33VT1G以低漏电流、宽温范围、紧凑封装为核心优势,是小功率稳压、过压保护场景的高性价比选择,适用于消费电子、工业控制、智能传感等多个领域。

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
