S-LBC807-40LT1G PNP型三极管产品概述

一、产品定位与核心属性

S-LBC807-40LT1G是乐山无线电(LRC)推出的小信号中等功率PNP型双极型晶体管(BJT),采用紧凑的SOT-23表面贴装封装,专为兼顾小体积、中功率负载及宽温适应性的场景设计。其核心基础参数明确了产品的应用边界:

  • 功率能力:最大耗散功率(Pd)225mW,可承载中等强度的小信号功率;
  • 电流能力:连续集电极电流(Ic)500mA,满足多数小功率负载驱动需求;
  • 电压能力:集射极击穿电压(Vceo)45V,射基极击穿电压(Vebo)5V,覆盖常见信号电压范围。

二、关键电性能参数深度解析

该器件的电性能参数针对信号放大与中小负载开关场景优化,核心参数的设计逻辑清晰:

1. 增益与频率特性

  • 直流电流增益(hFE):250@Ic=500mA、Vce=1.0V——大电流下仍保持较高增益,意味着在驱动中等负载时无需过多级联放大,简化电路设计;
  • 特征频率(fT):100MHz——可稳定工作于中高频信号场景(如几十MHz以内的音频、射频辅助放大),避免信号失真。

2. 开关与饱和特性

  • 集射极饱和电压(VCE(sat)):700mV——饱和压降适中,开关状态下的功耗低,适合LED驱动、继电器线圈控制等开关类应用;
  • 集电极截止电流(Icbo):100nA——截止状态漏电流极小,有效降低静态功耗,适配低功耗电路(如电池供电设备)。

3. 电压与温度适应性

  • 击穿电压:Vceo=45V(集射极反向击穿)、Vebo=5V(射基极反向击穿)——避免电路过压损坏,提升系统可靠性;
  • 工作温度范围:-55℃~+150℃——覆盖工业级宽温需求,可应用于户外、车载或高温环境的设备。

三、封装与可靠性设计

S-LBC807-40LT1G采用标准SOT-23封装,具备以下优势:

  • 体积紧凑:封装尺寸约1.6mm×2.9mm×1.1mm,大幅节省PCB空间,适配便携式电子设备(如智能手机、智能穿戴);
  • 引脚定义清晰:符合行业通用PNP引脚配置(通常1脚为基极、2脚为发射极、3脚为集电极),便于电路设计与焊接;
  • 可靠性验证:LRC对该器件进行了严格的环境与电应力测试,满足RoHS无铅要求,可长期稳定工作于工业与消费电子场景。

四、典型应用场景

结合参数特性,该器件的核心应用场景集中于小信号放大与中小负载开关,具体包括:

1. 信号放大电路

  • 音频前置放大:适配便携式音箱、耳机放大器的微弱音频信号放大;
  • 传感器信号调理:用于压力、温度、湿度传感器的输出信号放大(高增益hFE可有效提升微弱信号幅度);
  • 射频辅助放大:中高频(<100MHz)信号的缓冲放大,如蓝牙、WiFi模块的辅助链路。

2. 中小负载开关

  • LED驱动:小功率LED(如指示灯、背光)的驱动,500mA电流能力满足多数小LED的驱动需求;
  • 继电器控制:低功耗继电器线圈的驱动(饱和压降低,减少开关损耗);
  • 电源电路辅助:线性稳压电源的调整管、电池充电电路的开关控制。

3. 消费与工业电子

  • 消费电子:智能手机、平板的电源管理辅助电路、按键开关信号处理;
  • 工业控制:工业传感器模块、PLC辅助电路(宽温范围适配户外环境)。

五、品牌与品质保障

乐山无线电(LRC)是国内老牌半导体制造企业,拥有超过50年的晶体管研发与生产经验,产品广泛应用于家电、通信、汽车电子等领域。S-LBC807-40LT1G通过了严格的质量管控,符合IEC、JEDEC等行业标准,具备供货稳定、性价比高的特点,适合批量应用于各类中小型电子设备。

综上,S-LBC807-40LT1G是一款兼顾小体积、中功率、宽温适应性的PNP三极管,可有效满足信号放大与中小负载开关的多样化需求,是消费电子、工业控制等领域的高性价比选择。

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.
