LBTN560Y3T1G(NPN型双极晶体管)产品概述

一、产品核心定位与基础身份

LBTN560Y3T1G是乐山无线电(LRC) 推出的普通NPN型双极结型晶体管(BJT),属于中功率通用晶体管范畴——既具备中等电流承载能力,又兼顾耐压与高频性能,适用于开关控制、信号放大等多场景,是工业控制、消费电子、汽车电子领域的常用分立器件。

二、关键电气参数深度解析

核心参数明确了产品的应用边界,各参数的实际意义如下:

  1. 集电极连续电流(Ic):5A
    最大连续集电极电流为5A,可稳定驱动3-5A的中等功率负载(如小型直流电机、继电器线圈);脉冲电流峰值可提升至10-15A(需结合散热条件验证),满足瞬时大电流需求。
  2. 集射极击穿电压(Vceo):60V
    基极开路时,集电极与发射极的最大耐压为60V,完全覆盖12V、24V、48V主流低压系统(汽车电子、工业PLC),可抵御电路浪涌电压,降低击穿风险。
  3. 特征频率(fT):130MHz
    电流增益带宽积为130MHz,即β=1时的工作频率——说明在音频(20Hz-20kHz)、中频(几十kHz)甚至部分高频(如FM广播100MHz)电路中仍能有效放大,兼顾中功率与高频性能。
  4. 补充常规参数
    直流电流增益β通常在100-300(LRC中功率管典型范围),饱和压降Vce(sat)约0.2-0.5V(开关状态低损耗),满足开关效率与放大线性需求。

三、封装与物理特性

采用SOT-89表面贴装封装,具备以下特点:

  • 尺寸紧凑:典型尺寸2.9mm×2.8mm×1.5mm,适合小型化PCB设计(如便携式设备、小型控制模块);
  • 引脚布局:3引脚结构(官方标注:1脚=基极B、2脚=发射极E、3脚=集电极C),便于自动化贴装;
  • 散热注意:SOT-89散热能力有限,若连续工作电流≥3A,需通过PCB铜箔扩展(集电极引脚区域增加铜箔面积)或小型散热片辅助散热,避免结温过高。

四、典型应用场景梳理

结合参数特性,主要应用场景包括:

  1. 低压中功率开关:小型直流电机(12V/24V)驱动、继电器线圈(5A以内)控制、LED大电流阵列开关;
  2. 音频放大:10W以内桌面功放的末级推动、耳机放大器输出级;
  3. 工业控制:PLC数字输出级、传感器信号放大(中等电流负载)、小型电磁阀驱动;
  4. 消费电子:充电器辅助控制、小型家电(电风扇、豆浆机)功率调节;
  5. 汽车电子(小型部件):车载USB电流控制、日间行车灯驱动(12V系统适配)。

五、品牌与可靠性背书

由乐山无线电(LRC) 生产,该厂商是国内分立器件头部企业,产品符合RoHS、REACH环保标准,经多年市场验证,可靠性与供货稳定性突出,适合批量生产项目。

六、选型注意事项

  1. 散热评估:连续电流≥3A时,需优化PCB散热;
  2. 电压匹配:电源及浪涌电压不得超过60V;
  3. 引脚确认:安装前需参考官方datasheet确认引脚顺序;
  4. 替代参考:同参数替代型号包括LRC APN560(同封装)、NXP BCP56(Ic4A/Vceo80V,SOT-89封装)。

该产品以平衡的性能、紧凑的封装,成为中功率电路的高性价比选择。

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
