LMBT5087LT1G PNP型三极管产品概述

LMBT5087LT1G是乐山无线电(LRC)推出的一款PNP型小信号双极型晶体管(BJT),采用SOT-23表面贴装封装,专为低功耗、高频放大及低速开关场景设计,兼具宽温适应性与高增益特性,适用于工业控制、便携式电子等多种应用领域。

一、产品基本定位与核心属性

作为LRC旗下的通用型PNP三极管,LMBT5087LT1G的核心定位是小信号高频放大/开关器件,具备以下关键属性:

  • 类型:PNP型双极晶体管;
  • 封装:SOT-23(表面贴装,尺寸紧凑,适合高密度PCB布局);
  • 功率等级:低功耗(最大耗散功率300mW);
  • 频率特性:高频响应(特征频率40MHz)。

二、关键电气参数深度解析

LMBT5087LT1G的电气参数经过优化,平衡了放大能力、开关性能与可靠性,核心参数如下:

1. 耐压与电流承载能力

  • 集射极击穿电压(VCEO):50V(集电极-发射极反向击穿电压,保证直流工作电压≤50V时器件安全);
  • 最大集电极电流(IC):50mA(持续工作时集电极电流不超过50mA,适合小信号电路的电流驱动需求);
  • 射基极击穿电压(VEBO):3V(发射极-基极反向击穿电压,设计偏置电路时需注意发射极电压不得超基极3V,避免击穿)。

2. 放大与频率特性

  • 直流电流增益(hFE):[email protected]、5.0V(在集电极电流1mA、集射极电压5V的典型工作点下,电流增益达250,放大能力较强,适合小信号放大);
  • 特征频率(fT):40MHz(晶体管电流增益带宽积,即电流增益降为1时的频率,表明器件可稳定工作在40MHz以下的高频信号场景)。

3. 开关与截止性能

  • 集射极饱和电压(VCE(sat)):300mV(饱和状态下集射极压降仅0.3V,开关损耗低,适合低速开关应用);
  • 集电极截止电流(ICBO):10μA(反向截止时集电极漏电流≤10μA,漏电流小,保证低功耗与信号稳定性,尤其适合电池供电设备)。

4. 功率耗散与温度范围

  • 最大耗散功率(Pd):300mW(环境温度25℃时的最大允许功耗,小功耗设计无需额外散热措施);
  • 工作温度范围:-55℃~+150℃(宽温特性,可适应工业级环境、汽车电子(部分场景)及极端温度条件)。

三、封装形式与典型应用场景

LMBT5087LT1G采用SOT-23封装(尺寸约2.9×1.6×1.1mm),属于小型表面贴装封装,具有以下优势:

  • 体积小,节省PCB空间,适合便携式设备(如智能手机、可穿戴设备)的高密度布局;
  • 焊接工艺成熟,易实现自动化贴装,降低生产难度与成本。

其典型应用场景包括:

  1. 小信号放大电路:如音频前置放大、传感器信号放大(压力、温度传感器等);
  2. 高频振荡/混频电路:40MHz以下的射频振荡、混频模块;
  3. 低速开关电路:LED指示灯驱动、逻辑电平转换(如3.3V转5V)、小型继电器控制;
  4. 工业控制模块:PLC输入输出接口、传感器信号调理电路;
  5. 便携式电子设备:蓝牙耳机、智能手环等低功耗设备的信号处理单元。

四、可靠性与环境适应性

LMBT5087LT1G的设计兼顾可靠性与环境适应性:

  • 宽温工作:-55℃~+150℃的温度范围,可覆盖大部分工业、汽车及户外应用场景;
  • 低漏电流:ICBO≤10μA,减少静态功耗,延长电池设备续航;
  • 高参数一致性:LRC的生产工艺保证批次间参数波动小,适合批量应用;
  • 抗击穿能力:VCEO50V、VEBO3V的耐压设计,可承受一定的过压冲击。

五、品牌背景与产品优势

乐山无线电(LRC)是国内知名的半导体器件制造商,拥有多年分立器件生产经验,LMBT5087LT1G的核心优势包括:

  • 性价比高:国产器件替代进口,成本可控,适合大规模应用;
  • 质量可靠:符合工业级标准,通过多项可靠性测试(如温度循环、湿度测试);
  • 供货稳定:LRC具备完善的产能体系,可满足长期批量需求;
  • 兼容性强:参数与国际同类产品(如MMBT5087)兼容,可直接替换。

综上,LMBT5087LT1G是一款性能均衡的PNP小信号三极管,适合对尺寸、功耗、高频性能有要求的多种电子应用场景,是工业控制、便携式设备等领域的理想选择。

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.
