S-LBC846BLT1G 通用NPN双极型晶体管产品概述

一、产品基本属性

S-LBC846BLT1G是乐山无线电(LRC)推出的通用NPN型双极型晶体管(BJT),属于小功率通用三极管范畴,核心定位为中小信号放大与低速开关应用。该器件采用SOT23表面贴装封装,体积紧凑,适配高密度PCB设计需求,是消费电子、工业控制、车载电子等领域的常用基础器件。

二、核心电气参数解析

该器件的电气参数经过优化,兼顾耐压、电流、增益与功耗平衡,关键参数如下:

  1. 耐压性能:集射极击穿电压(VCEO)达65V,射基极击穿电压(VEBO)为6V,可满足中等电压等级的电路设计需求,避免反向过压损坏;
  2. 电流与功率:最大集电极电流(IC)为100mA,最大耗散功率(Pd)为225mW,适合小功率负载驱动;
  3. 放大特性:直流电流增益(hFE)在2.0mA集电极电流、5.0V集射极电压下稳定在200,增益一致性较好;特征频率(fT)达100MHz,可支持中等频率的信号处理;
  4. 饱和与截止特性:集射极饱和电压(VCE(sat))仅250mV,开关损耗低,适合开关应用;集电极截止电流(ICBO)为15nA,漏电流小,低功耗场景下表现优异;
  5. 温度适应性:工作温度范围覆盖-55℃至+150℃,宽温特性使其可在工业级、车载级等恶劣环境下稳定工作。

三、封装与物理特性

S-LBC846BLT1G采用SOT23表面贴装封装,这是一种小型化封装形式,典型尺寸约为2.9mm(长)×1.6mm(宽)×1.1mm(高),引脚数为3(基极B、发射极E、集电极C,引脚顺序通常为1=B、2=E、3=C)。封装材料为环氧树脂,具备良好的耐温、耐湿性能,且符合RoHS环保要求(无铅无卤),适配现代电子产品的环保标准。小体积设计使其可在高密度PCB上实现紧凑布局,降低电路整体尺寸。

四、典型应用场景

基于其电气参数与封装特性,S-LBC846BLT1G的典型应用包括:

  1. 小信号放大:音频前置放大电路、传感器微弱信号放大(如温度传感器、压力传感器的信号调理);
  2. 低速开关控制:小功率LED驱动(100mA电流满足普通LED的驱动需求)、继电器线圈驱动(需预留功率余量)、数字逻辑电路的辅助开关;
  3. 工业与车载电子:工业仪表的信号处理单元、车载电子的辅助控制电路(宽温特性适配车载环境的温度波动);
  4. 消费电子:手机、平板等便携设备的电源辅助电路、按键检测电路、指示灯驱动等。

五、品牌与可靠性保障

S-LBC846BLT1G由乐山无线电(LRC)生产,该厂商是国内半导体行业的知名企业,具备成熟的晶体管生产工艺与质量控制体系。产品经过严格的参数一致性测试与可靠性验证(包括宽温老化、电应力测试等),确保批量应用中的性能稳定。此外,LRC的产品符合JEDEC、IEC等国际标准,可满足不同行业的认证要求,是替代进口通用三极管的可靠选择。

该器件以平衡的性能、紧凑的封装和宽温适应性,成为中小功率电子电路的高性价比基础器件。

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
