L2SC1623QLT1G 产品概述

一、产品核心身份识别

L2SC1623QLT1G是乐山无线电(LRC) 推出的一款NPN型双极结型晶体管(BJT),属于小功率通用三极管范畴。作为单管封装器件,它采用SOT-23小型表面贴装封装,适配对体积、功耗有严格要求的电子电路设计,是原型开发、小型设备量产的常用基础器件之一。

二、关键电性能参数详解

该器件的核心参数围绕“小功率、高频响应、宽温稳定”设计,具体特性如下:

1. 功率与电流承载

  • 最大耗散功率Pd=225mW:属于典型小功率器件,能稳定工作在低功耗场景(如便携式设备待机模式);
  • 集电极最大连续电流Ic=150mA:可直接驱动小型负载(如小功率LED、微型继电器、低功耗电机);
  • 集射极饱和电压VCE(sat)=1V:开关应用中导通损耗低,提升电路效率(如LED闪烁电路的驱动损耗可控制在150mW以内)。

2. 电压耐受与安全裕量

  • 集射极击穿电压Vceo=50V:远高于多数小信号电路的工作电压(5V~24V),提供充足安全裕量,避免电压波动损坏器件;
  • 射基极击穿电压Vebo=7V:防止基极-发射极反向偏置时击穿,保障电路长期稳定。

3. 增益与频率响应

  • 直流电流增益hFE=120:小信号放大场景中信号放大能力稳定(如音频前置放大、传感器输出信号调理);
  • 特征频率fT=250MHz:高频下仍保持有效放大特性,可用于100MHz以下的射频辅助电路、高速开关(如信号切换模块)。

4. 截止与漏电流特性

  • 集电极截止电流Icbo=100nA(典型值):漏电流极小,静态功耗低,适配对功耗敏感的便携式设备(如蓝牙耳机、智能手环的辅助控制)。

三、封装形式与典型应用场景

1. 封装特点

采用SOT-23表面贴装封装,尺寸紧凑(2.9mm×1.6mm×1.1mm),占用PCB面积小,适配高密度电路设计(如智能手机主板、IoT设备模块);引脚布局清晰,焊接工艺成熟,兼容自动化生产流程。

2. 典型应用场景

  • 小信号放大:音频前置放大、压力/温度传感器的输出信号调理;
  • 高速开关控制:LED闪烁电路、微型电机驱动(低功率)、小型继电器驱动;
  • 便携式设备辅助电路:蓝牙耳机电源控制、智能手表信号切换模块;
  • 电源管理反馈:低功率DC-DC转换器过流保护、线性稳压器辅助控制。

四、可靠性与环境适应性

该器件的工作温度范围覆盖**-55℃~+150℃**,宽温特性使其能在极端环境下稳定工作(如工业控制设备低温启动、高温环境持续运行);结合低漏电流、高击穿电压设计,长期可靠性突出,适配车载周边电路、工业传感器模块等对稳定性要求高的场景。

五、品牌与质量保障

由乐山无线电(LRC)生产,LRC作为国内半导体老牌厂商,拥有成熟的设计制造工艺,产品符合RoHS环保标准,单管封装一致性好,满足批量生产质量要求;该型号为通用型器件,市场供应稳定,替代型号易获取,降低供应链风险。

综上,L2SC1623QLT1G是一款性价比高、适配性强的小功率NPN三极管,适合各类小型电子设备的信号放大与开关控制需求。

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
