S-LBTN180Z4TZHG 产品概述

一、产品简介

S-LBTN180Z4TZHG 是乐山无线电(LRC)生产的一款通用型 NPN 双极晶体管,采用 SOT-223 封装,面向小功率开关与放大场合。器件额定集电极电流为 1A,集-射击穿电压 80V,适合中等电压等级的开关与线性应用。器件规格均衡,适用于对成本与体积有要求的应用场景。

二、主要电气参数

  • 晶体管类型:NPN
  • 最大集电极电流 Ic:1 A
  • 集-射击穿电压 Vceo:80 V
  • 最大耗散功率 Pd:833 mW(典型指标,实际请参见详细资料并考虑散热条件)
  • 直流电流增益 hFE:63(测试条件 Ic=5 mA、Vce=2 V)
  • 特征频率 fT:180 MHz(适合中高频小信号放大)
  • 集电极截止电流 Icbo:10 μA(典型)
  • 集-射极饱和电压 VCE(sat):典型 ≤500 mV(标注条件 500 mA、50 mA)
  • 射-基击穿电压 Vebo:5 V
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:SOT-223(数量:1 只/件)

三、性能特点

  • 电压耐受良好:Vceo 80 V,可在较高电压工况下可靠工作,适合通用开关应用;
  • 中等至高频特性:fT 180 MHz,适用于小信号放大(如射频前级、驱动级)与快速开关;
  • 较低饱和压:在指定条件下 VCE(sat) 约 500 mV,有助于降低开关损耗;
  • 宽温域可靠性:-55 ℃ 至 +150 ℃ 的工作温度范围,适合工业级环境;
  • SOT-223 封装便于 PCB 安装并有利于散热改进。

四、典型应用场景

  • 开关电源与稳压器的次级开关或驱动器;
  • 继电器、步进电机驱动与功率开关(低至中等电流);
  • 音频前级放大与小信号放大电路;
  • 接口电平移位、缓冲驱动与通用开关场合;
  • 通信设备的中频/低端射频放大(视具体工作频率与增益要求)。

五、使用建议与注意事项

  • 开关时的基极驱动:若器件用于饱和开关状态,建议采用合适的基极余量(一般按强迫 βf ≈ 10~20 估算),例如在 500 mA 集电极电流下,基极驱动电流应在几十 mA 量级(需结合驱动器能力和热耗考虑);
  • 功率与散热:标称 Pd 为 833 mW,实际耗散能力与 PCB 散热条件、环境温度有关。建议在高电流或持续功耗场合配合大面积铜箔或外部散热片,并做降额设计;
  • 极限参数遵循:避免超过 Vceo=80 V、Vebo=5 V 等极限值,击穿会造成不可逆损伤;
  • 泄漏与噪声:Icbo 典型为 10 μA,低漏电流利于高阻电路,但在高温下漏电可能上升,注意热稳定性设计;
  • 引脚与封装:SOT-223 对比 SOT-23 有更好的散热通道,但不同厂家的引脚排列可能有所差异,安装前请参阅官方数据手册确认引脚定义与焊接建议。

六、封装与采购建议

SOT-223 封装兼顾小型化与散热性能,适合表贴工艺。选型时若需更大功耗处理能力或更高电流能力,可考虑 TO-220、DPAK 等更大封装。购买时请确认原厂型号、批次和完整的数据手册,必要时索取样品验证电气与热性能,避免直接替换而不做验证。

总结:S-LBTN180Z4TZHG 是一款参数均衡、适用于中低功率开关与小信号放大的 NPN 晶体管。若用于持续大电流或高功耗场合,应重视散热设计与基极驱动匹配,以保证器件在额定范围内稳定工作。若需更详细的电气特性曲线、封装引脚图及热阻参数,请参考厂商完整数据手册。

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
