LBC847CWT1G 三极管产品概述

一、产品核心身份与基本定位

LBC847CWT1G是乐山无线电(LRC) 推出的一款NPN型双极结型晶体管(BJT),属于小信号功率三极管范畴。其采用超小型贴片封装SC-70,体积紧凑、功耗低,核心面向需要高频性能、高增益及宽温适应性的电子电路设计,是便携设备、工业控制及射频前端等场景的常用器件。

二、关键电性能参数解析

该器件的电性能参数经过严格设计与测试,核心指标覆盖安全工作边界、放大开关特性及温度适应性,具体如下:

(1)安全工作边界参数

  • 集射极击穿电压(Vceo):45V:基极开路时,集电极与发射极之间能承受的最大电压,确保电路在高压环境下无击穿风险;
  • 射基极击穿电压(Vebo):6V:基极开路时,发射极与基极之间的最大耐压,避免反向偏置时的击穿损坏;
  • 最大集电极电流(Ic):100mA:连续工作时集电极允许的最大电流,限定了器件的负载能力;
  • 最大耗散功率(Pd):150mW:常温(25℃)下器件能持续耗散的最大功率,超出需降额使用。

(2)放大与开关特性

  • 直流电流增益(hFE):420@100mA、5.0V:典型工作点(集电极电流100mA、集射极电压5V)下的电流放大倍数,高增益特性可有效提升小信号强度;
  • 集射极饱和电压(VCE(sat)):600mV:开关状态下的压降,低饱和压降显著降低开关损耗,提升电路效率;
  • 特征频率(fT):100MHz:反映高频工作能力,fT越高,高频信号下的放大性能越稳定,适合射频前端、振荡电路;
  • 集电极截止电流(Icbo):5μA:发射极开路时的漏电流,低漏电流减少静态功耗,提升电路信噪比。

(3)温度适应性

工作温度范围为**-55℃~+150℃**,覆盖工业级宽温要求,可在极端环境(如高温工业现场、低温户外设备)中稳定工作,无需额外温度补偿。

三、封装与典型应用场景

(1)SC-70封装特点

采用超小型表面贴装封装(又称SOT-323),尺寸仅约2.0mm×1.25mm×0.8mm,具备三大优势:

  • 小型化适配:适合高密度PCB布局,满足便携设备的小型化需求;
  • 贴装便捷:与自动化贴装设备兼容,提升量产效率;
  • 散热可控:配合合理PCB设计,可满足150mW功耗的散热要求。

(2)典型应用领域

基于电性能与封装特点,该器件广泛用于:

  • 小信号放大:音频前置放大、传感器信号调理(温度/压力传感器);
  • 低功耗开关:LED驱动、小型继电器控制、电源切换;
  • 高频电路:射频前端信号放大、局部振荡电路(fT=100MHz支撑);
  • 工业与车载:PLC输入输出接口、车载仪表盘信号处理(宽温适配);
  • 便携电子:智能手机、智能穿戴的电源管理、按键控制(SC-70封装适配)。

四、品牌与可靠性保障

LBC847CWT1G由国内知名半导体厂商乐山无线电(LRC) 生产,产品具备三大可靠性优势:

  • 参数一致性:批量产品的hFE、VCE(sat)等关键参数离散性小,便于电路设计与量产;
  • 可靠性测试:经过高温存储、温度循环、湿度老化等测试,满足5年以上长期工作需求;
  • 环保与供货:符合RoHS标准,产能稳定,可保障下游客户量产供货。

该器件以高性价比、宽温适应性及高频性能,成为中小功率电子电路设计的常用选择。

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
