一、产品基本属性

该晶体管核心属性清晰,定位明确:

  • 晶体管类型:NPN双极结型晶体管(BJT)
  • 品牌与型号:PANJIT(强茂)BC846A_R1_00001
  • 封装形式:SOT-23-3(3引脚表面贴装封装)
  • 应用定位:小信号放大、低速开关控制、信号调理、小型驱动

二、核心电气参数详解

参数针对小信号场景优化,关键指标如下:

  1. 功率与电流容量:
    • 最大集电极电流(Ic):100mA(满足小负载驱动需求)
    • 最大耗散功率(Pd):330mW(封装散热匹配小功率应用)
  2. 耐压特性:
    • 集射极击穿电压(Vceo):65V(高于普通小信号管,支持中高压小信号电路)
    • 射基极击穿电压(Vebo):6V(防止基极-发射极反向过压损坏)
  3. 直流性能:
    • 直流电流增益(hFE):110(典型值,测试条件:Ic=2mA、Vce=5V)——小信号工作点增益稳定,放大失真小
    • 集射极饱和电压(VCE(sat)):600mV(典型值,测试条件:Ic=10mA、Ib=0.5mA)——开关状态损耗低
    • 集电极截止电流(Icbo):15nA(典型值,测试条件:Vcb=30V)——截止状态漏电流极小,信号干扰少

三、封装与物理特性

采用SOT-23-3封装,是小型化设计的主流选择,特点显著:

  • 体积紧凑:引脚间距小,适配高密度PCB布局(如智能穿戴、小型家电)
  • 表面贴装:支持自动化焊接,提升生产效率
  • 引脚定义(标准SOT-23):1脚(基极B)、2脚(发射极E)、3脚(集电极C),便于电路设计与焊接

四、工作温度与环境适应性

支持宽温度范围工作:-55℃至+150℃,覆盖工业级与部分高温场景需求,可应用于:

  • 户外电子设备(如智能传感器、小型监控)
  • 工业控制现场(如PLC输入输出模块)
  • 高温环境消费电子(如小型家电内部)

五、典型应用场景

因参数平衡,广泛用于以下场景:

  1. 小信号放大:音频前置放大、传感器信号调理(温度/压力传感器输出放大)
  2. 低速开关:小型继电器驱动、LED指示灯控制、逻辑电平转换
  3. 消费电子:手机充电管理辅助电路、智能音箱信号处理
  4. 工业辅助:PLC输入信号放大、小功率电机驱动

六、关键性能优势

  1. 增益稳定:小信号工作点hFE典型值110,放大电路失真小;
  2. 开关损耗低:VCE(sat)=600mV,开关状态功耗低,适合长时间工作;
  3. 漏电流极小:Icbo=15nA,截止状态信号干扰少,适配精密电路;
  4. 耐压范围宽:Vceo=65V,替代低耐压管,减少设计冗余;
  5. 宽温适配:-55~150℃,无需额外散热/补偿,降低设计成本。

总结:BC846A_R1_00001是一款性价比高的通用NPN小信号三极管,平衡了耐压、电流、增益与体积,适配多种小型化、小功率电子电路设计。

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
