LUDZS12BT1G 稳压二极管产品概述

一、产品基本定位

LUDZS12BT1G是乐山无线电(LRC) 推出的独立式稳压二极管,属于小型化表面贴装器件。该产品专为低功率、高密度电路设计,核心功能是提供稳定的12V电压基准,适配消费电子、通信设备、便携式产品等多类场景,兼具低功耗、高可靠性与小型化优势。

二、核心电气参数解析

该产品的关键参数直接决定了其应用场景与性能表现,具体解析如下:

1. 稳压值与精度

标称稳压值为12V,工作范围覆盖11.74V~12.24V,误差约2%(12V基准下波动±0.26V)。此精度满足大多数常规稳压需求,无需额外复杂的稳压电路设计,可直接作为电压基准使用。

2. 反向漏电流

反向漏电流仅100nA(@9V反向偏置),是该产品的核心优势之一。漏电流极低意味着:在反向电压未达稳压值时(非稳压工作状态),几乎不消耗额外电能,非常适合对功耗敏感的便携式设备(如智能手环、蓝牙耳机),能有效延长电池续航。

3. 耗散功率

最大耗散功率为200mW,虽属于小功率范畴,但覆盖了多数低功率电路的稳压需求(如单片机、传感器的供电稳压),适配场景广泛。

4. 动态阻抗

动态阻抗(Zzt)为30Ω。动态阻抗越低,稳压管在负载电流变化时的电压波动越小——比如当负载电流有微小波动时,输出电压仍能保持稳定,稳压特性可靠。

5. 封装

采用SOD-323 表面贴装无引脚封装,典型尺寸为长1.6mm×宽0.8mm×高0.5mm,体积紧凑,适配高密度PCB布局,适合批量自动化贴装生产。

三、封装与物理特性

SOD-323封装具有以下实用特性:

  • 无引脚设计:直接贴装于PCB表面,无需钻孔,生产效率高;
  • 耐热性:可承受常规回流焊工艺(峰值温度约260℃,持续时间≤10秒),适配自动化生产;
  • 机械强度:封装材料抗轻微振动,能适应运输与使用中的环境变化,可靠性较高。

四、典型应用场景

该产品凭借低功耗、小型化等特点,广泛应用于以下场景:

1. 消费电子领域

智能手机、平板电脑、智能手表等便携式设备的辅助稳压电路——利用低漏电流特性降低待机功耗,延长电池续航;

2. 通信设备

路由器、交换机、无线AP等设备中的低功率模块稳压(如指示灯电路、控制芯片供电);

3. 小型电源产品

USB充电器、移动电源的输出辅助稳压,确保输出电压稳定在12V附近;

4. 工业控制

小型传感器节点、PLC的辅助稳压电路,适配高密度PCB设计;

5. 车载电子(部分低功率场景)

车载蓝牙、USB充电口等低功率模块的稳压(需结合具体汽车级认证要求)。

五、性能优势总结

LUDZS12BT1G的核心竞争力体现在:

  1. 低功耗:100nA反向漏电流,显著降低待机损耗,适合电池供电产品;
  2. 稳定可靠:2%稳压精度+30Ω低动态阻抗,负载/温度变化时电压波动小;
  3. 小型化:SOD-323封装节省PCB空间,适配电子设备轻薄化趋势;
  4. 生产友好:表面贴装设计适合自动化生产,降低制造成本;
  5. 品牌保障:LRC作为国内知名半导体厂商,产品质量稳定,供货可靠。

综上,LUDZS12BT1G是一款高性价比的小型稳压二极管,可满足多类低功率稳压场景的需求,是消费电子、通信等领域的理想选择。

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
