LUDZS30BT1G稳压二极管产品概述

LUDZS30BT1G是乐山无线电(LRC)推出的一款独立式稳压二极管,核心聚焦30V稳压应用场景,凭借精准的电压控制、低功耗特性及宽温适应性,成为工业控制、消费电子、汽车电子等领域的可靠稳压解决方案。作为国内老牌半导体厂商的成熟产品,其参数一致性与可靠性经过市场验证,适配高密度PCB设计需求。

一、核心身份与品牌背景

LUDZS30BT1G隶属于LRC稳压二极管系列,型号命名中“30”直接对应标称稳压值30V,“BT1G”标注封装及参数规格(SOD-323封装)。乐山无线电(LRC)作为国内半导体行业的标杆企业,拥有数十年分立器件研发制造经验,产品覆盖二极管、三极管、MOS管等全品类,其稳压二极管以高一致性、宽温可靠性著称,广泛应用于国内外电子整机领域。

二、关键电气参数深度解析

该产品的电气参数针对稳压性能做了针对性优化,核心参数如下:

  • 稳压精度与范围:标称稳压值30V,实际工作范围为29.19V~30.69V,覆盖±3%公差区间,满足多数常规稳压需求;
  • 低反向漏电流:在23V反向偏置下,漏电流仅100nA,大幅降低静态功耗,适合低功耗场景(如便携式设备待机状态);
  • 功耗与电流容量:最大耗散功率200mW,结合稳压值可计算最大工作电流约6.67mA((I_{zm}=P_d/V_z)),适配小功率负载;
  • 动态阻抗稳定性:测试电流下阻抗((Z_{zt}))与拐点电流下阻抗((Z_{zk}))均为200Ω,稳压输出受负载波动影响小,电压稳定性优异;
  • 宽温工作范围:结温范围覆盖-55℃~+150℃,可适应工业级低温(如户外设备)、车载级高温(如发动机舱周边)等严苛环境。

三、封装与物理特性

LUDZS30BT1G采用SOD-323小型表面贴装封装,尺寸紧凑(典型值1.6mm×0.8mm×0.6mm),适配高密度PCB布局,有效节省板级空间。封装符合RoHS无铅环保标准,引脚为镀锡工艺,焊接兼容性强,支持自动化贴装(SMT),提升生产效率。

四、性能优势与可靠性

  1. 低功耗适配:100nA的反向漏电流在低负载时几乎可忽略,延长电池供电设备的续航时间;
  2. 宽温稳定性:-55℃~+150℃的结温范围,确保极端温度下稳压性能无明显衰减;
  3. 电压一致性:±3%的稳压公差范围,批量应用时参数一致性好,减少电路调试成本;
  4. 抗干扰能力:稳定的动态阻抗可抑制负载变化或输入电压波动带来的输出电压波动,提升电路可靠性。

五、典型应用领域

该产品因参数特性,广泛应用于以下场景:

  • 消费电子:便携式设备(蓝牙耳机、智能手环)的电源稳压、传感器参考电压;
  • 工业控制:PLC模块、工业传感器的稳压电路,适应车间宽温环境;
  • 汽车电子:车载仪表盘背光、胎压监测传感器的辅助稳压,满足车规级温度要求;
  • 通信设备:小型基站、路由器的DC-DC输出稳压,适配高密度PCB设计;
  • 电源模块:低功率电源的输出电压钳位、基准电压源。

六、总结

LUDZS30BT1G作为LRC推出的30V独立式稳压二极管,以精准稳压、低漏电流、宽温范围为核心优势,结合SOD-323小封装的灵活性,覆盖消费、工业、汽车等多领域应用。其参数设计兼顾性能与成本,是中小功率稳压场景的高性价比选择,适合批量应用于各类电子整机产品。

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
