LBC847AWT1G NPN型双极晶体管产品概述

一、产品基本定位与核心属性

LBC847AWT1G是乐山无线电(LRC)推出的通用型NPN双极型晶体管(BJT),采用超小型SC-70表面贴装封装,主打低功耗中小信号放大与小负载开关应用,适配便携电子、工业控制等多场景需求,是中小信号电路设计的常用选型之一。

二、关键电气参数解析

1. 耐压与电流能力

  • 集射极击穿电压(Vceo):45V,可支撑中等电压环境下的电路设计(如24V工业控制、12V消费电子);
  • 射基极击穿电压(Vebo):6V,有效防止反向偏置时的过压损坏,保护晶体管及周边电路;
  • 最大集电极电流(Ic):100mA,满足小负载驱动(如LED、微型继电器)需求;
  • 集电极截止电流(Icbo):仅5μA,漏电流控制优异,降低静态功耗与信号干扰,提升电路稳定性。

2. 功率与增益特性

  • 最大耗散功率(Pd):150mW,适配低功耗电路设计(如电池供电的便携设备);
  • 直流电流增益(hFE):在2.0mA、5.0V条件下稳定于110,线性放大区性能可靠,适合音频小信号、传感器信号放大;
  • 特征频率(fT):100MHz,支持中等频率信号处理(如10MHz以下的射频辅助电路、高速开关信号),兼顾低频放大与高频开关能力。

3. 饱和开关性能

  • 集射极饱和电压(VCE(sat)):100mA集电极电流、5mA基极电流下仅600mV,饱和压降低,开关过程中损耗小、响应速度快,适合小负载开关应用(如LED驱动、信号通道切换)。

三、工作环境与可靠性

1. 宽温适应能力

工作温度范围覆盖**-55℃+150℃**,可稳定运行于工业控制(-40℃+85℃)、户外电子(低温环境)等恶劣场景,无需额外散热设计即可满足多数应用需求。

2. 超小型封装优势

采用SC-70表面贴装封装,典型尺寸约1.6mm×1.0mm×0.8mm,体积超小,适配高密度PCB布局,完美契合便携设备(如智能穿戴、蓝牙耳机)的小型化趋势,且表面贴装工艺便于自动化生产,降低制造成本。

四、典型应用场景

  1. 便携电子设备:手机、智能手环、蓝牙耳机等产品的信号放大(如音频前置放大)、电源开关控制(如电池供电切换);
  2. 工业控制模块:传感器信号放大(如温度、压力传感器)、小负载继电器驱动、工业仪表的信号处理电路;
  3. 消费电子:小型音频设备(如耳机放大器)、LED指示灯驱动、遥控器信号放大、玩具电子电路;
  4. 汽车辅助电子:车载小信号处理(如仪表盘指示灯驱动、传感器信号转换),宽温特性适配车载环境(需确认汽车级认证,参数已满足基础要求)。

五、品牌与市场优势

乐山无线电(LRC)作为国内老牌半导体厂商,拥有数十年晶体管研发制造经验,产品一致性好、品质可靠,符合RoHS等环保标准;LBC847AWT1G参数均衡,兼顾放大与开关性能,性价比高,适合量产应用,是替代进口同类产品(如2N3904)的优选方案之一。

该产品以其均衡的参数、可靠的性能及超小型封装,成为中小信号电路设计中“低成本、高适配”的核心选型。

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
