S-LBZT52C6V8T1G 稳压二极管产品概述

S-LBZT52C6V8T1G是乐山无线电(LRC)推出的独立式小功率稳压二极管,专为对体积、功耗及环境适应性要求较高的电子电路设计,核心功能是提供稳定的6.8V电压基准,广泛应用于消费电子、工业控制、汽车电子等领域。

一、产品基本定位与核心参数

该产品属于LRC稳压二极管系列中的常规型号,针对小功率稳压场景优化:

  • 核心稳压值:标称6.8V,实际工作范围6.4V~7.2V(覆盖±5%精度),满足一般电路对电压精度的需求;
  • 封装形式:SOD-123(超小型表面贴装封装),尺寸紧凑,适配高密度PCB布局;
  • 类型与品牌:乐山无线电(LRC)生产的独立式稳压管,无并联/串联组合,结构简单可靠。

二、关键性能指标详解

  1. 稳压与阻抗特性
    标称稳压值6.8V,稳压范围6.4V~7.2V(±5%精度),可覆盖多数低/中精度电压需求;动态阻抗Zzt=15Ω(稳压工作点的阻抗特性),反向击穿前阻抗Zzk=80Ω,阻抗稳定,减少电压波动对后级电路的影响。

  2. 低反向漏电流
    在4V反向电压下,反向电流仅2uA,属于低漏电流设计,可降低静态功耗,避免对前级驱动电路造成负载干扰,尤其适合电池供电或低功耗电路。

  3. 功率与温度适应性
    最大耗散功率Pd=500mW,支持最大持续工作电流约73mA(计算:Pd/Vz≈500mW/6.8V);工作结温范围-55℃~+150℃,覆盖工业级宽温环境,可稳定工作于高温、低温或温度变化剧烈的场景。

三、封装与可靠性设计

SOD-123封装是该产品的核心优势:

  • 尺寸优势:封装尺寸约1.6mm×0.8mm×0.6mm,体积仅为传统插件二极管的1/10,大幅节省PCB空间,适合便携式设备、小型化模块;
  • 可靠性保障:采用耐高温环氧树脂封装,具备抗振动、抗冲击能力,结合宽温结温范围,满足汽车电子、工业控制等对可靠性要求较高的场景;
  • 工艺兼容性:支持回流焊、波峰焊等表面贴装工艺,与常规SMT生产线兼容,生产效率高。

四、典型应用场景

因体积小、功耗低、宽温稳定,适用于以下场景:

  1. 小功率电源稳压:为MCU、传感器、LED驱动等小功率负载提供6.8V稳定供电,替代复杂线性稳压芯片,简化电路;
  2. 电压基准源:作为简单基准电压,用于ADC参考、模拟电路偏置等,精度满足一般测试与控制需求;
  3. 过压保护:配合限流电阻,当输入电压超6.8V时反向击穿导通,箝位电压保护后级敏感电路;
  4. 信号箝位:在音频、视频等模拟电路中,将信号峰值箝位在6.8V,防止过冲损坏后端器件。

五、选型注意事项

  1. 功耗限制:实际工作电流需≤73mA(最大耗散功率以内),避免结温过高影响精度或损坏器件;
  2. 限流电阻计算:需根据输入电压与稳压值的差值计算限流电阻(R=(Vin-Vz)/Iz),确保工作在反向击穿区;
  3. 精度适配:若电路要求精度高于±5%,需结合温度系数补偿,或选用更高精度型号。

总结:S-LBZT52C6V8T1G凭借小体积、低功耗、宽温稳定及可靠性能,成为小功率稳压场景的高性价比选择,适合多数常规电子电路的稳压、基准及保护需求。

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
