LBC807-40WT1G 产品概述

概要

LBC807-40WT1G 是一款由乐山无线电(LRC)生产的高性能三极管(BJT),属于PNP类型。该器件以其小尺寸、低功耗和高性能特性,广泛应用于各种电子设备中,包括音频放大器、切换电路、信号处理和功率管理等领域。

基础参数

  • 功率(Pd): 200 mW
    • 这表明该三极管在正常工作条件下可以承受的最大功率,确保在设计时不会超过此阈值,避免过热和损坏。
  • 商品分类: 三极管(BJT)
    • 作为一种基本的电子器件,三极管广泛用于放大和切换应用。
  • 工作温度: -55℃ ~ +150℃
    • 宽泛的工作温度范围使得LBC807-40WT1G适用于各种环境条件下的应用,从极寒到高温环境。
  • 晶体管类型: PNP
    • PNP三极管在电路设计中常用于负载开关和信号放大。

电气特性

  • 特征频率(fT): 100 MHz
    • 高特征频率表明该三极管能够处理高频信号,适合用于通信、射频和其他高频应用。
  • 直流电流增益(hFE@Ic,Vce): 250 @ 100 mA, 1.0 V
    • 直流电流增益是衡量三极管放大能力的一个关键参数。该值表示在集电极电流为100 mA、集电极-发射极电压为1.0 V时,基极输入电流与集电极输出电流的比值。
  • 集射极击穿电压(Vceo): 45 V
    • 集射极击穿电压是指在基极无输入信号情况下,集电极与发射极之间允许的最大电压。超过此值可能导致器件损坏。
  • 集电极-发射极饱和电压(VCE(sat)@Ic,Ib): 700 mV @ 500 mA, 50 mA
    • 饱和电压表示当三极管完全导通时,集电极与发射极之间的最小电压差。低饱和电压意味着更低的能耗和更高的效率。

其他重要参数

  • 集电极截止电流(Icbo): 5 uA
    • 集电极截止电流是指在基极无输入信号情况下,集电极通过的极小电流。这一参数对于确保器件在静态状态下的低功耗非常重要。
  • 集电极电流(Ic): 500 mA
    • 最大允许的集电极电流,超过此值可能导致过热或损坏。

封装和品牌信息

  • 封装: SC-70
    • SC-70封装是一种小型化封装形式,适合于空间有限但要求高性能的应用场景。
  • 品牌: 乐山无线电(LRC)
    • 乐山无线电是一家具有丰富经验和良好声誉的电子元器件制造商,提供高质量和可靠性的产品。

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
