MMBT8550D 产品概述

概要

MMBT8550D 是一种由先科(ST)生产的PNP型双极晶体管(BJT),属于小信号三极管家族。它以其高性能、低噪声和广泛的应用场景而闻名,特别适用于各种电子设备中的信号放大和开关应用。

基础参数

  • 功率(Pd): 350 mW
    • 这表明该三极管在正常操作条件下可以承受的最大功率,确保其在各种应用中保持稳定运行。
  • 商品分类: 三极管(BJT)
    • 作为一种基本的电子元器件,三极管广泛用于信号放大、开关和其他电子电路中。
  • 晶体管类型: PNP
    • PNP型三极管与NPN型相比,具有不同的极性和工作方式,但功能相似。PNP型通常用于需要负电压控制的场景。
  • 特征频率(fT): 100 MHz
    • 特征频率是指在给定条件下,三极管的电流增益下降到1时的频率。高特征频率意味着该三极管适合高频应用。
  • 直流电流增益(hFE@Ic,Vce): 160 @ 100 mA, 1 V
    • 直流电流增益是指基极电流与集电极电流之间的比值。在这里,hFE为160,表示基极电流为100 mA时,集电极电流可以达到160倍。这是一个重要的参数,用于评估三极管的放大能力。
  • 集射极击穿电压(Vceo): 25 V
    • 这是指在没有基极电流输入的情况下,集电极与发射极之间可以承受的最大电压。超过这个值可能导致三极管损坏。
  • 集电极-发射极饱和电压(VCE(sat)@Ic,Ib): 500 mV @ 500 mA, 50 mA
    • 饱和电压是指当三极管完全导通时,集电极与发射极之间的最小电压。在这里,500 mA的集电极电流和50 mA的基极电流下,饱和电压为500 mV。这是一个重要的参数,用于评估三极管在开关模式下的性能。
  • 集电极截止电流(Icbo): 100 nA
    • 这是指在没有基极电流输入的情况下,集电极与发射极之间的漏电流。低漏电流意味着更好的隔离性和更低的静态功耗。
  • 集电极电流(Ic): 600 mA
    • 这是指该三极管可以承受的最大连续集电极电流,确保其在高电流应用中保持稳定。

封装和品牌

  • 封装: TO-236-3
    • TO-236是一种小型SMD封装,适合于现代电子产品中的空间有限场景。
  • 品牌: 先科(ST)
    • 作为全球领先的半导体制造商,先科提供高质量、可靠性的电子元器件。

MMBT8550D 适用于各种需要高频信号放大和开关控制的电子系统,例如:

  • 音频设备: 由于其高频特性和低噪声性能,MMBT8550D 可以用于音频放大器、音频处理器等设备。
  • 通信设备: 在无线通信、有线通信等领域,MMBT8550D 可以作为信号放大器或开关元件。
  • 工业控制系统: 在工业自动化中,MMBT8550D 可以用于控制和监测各种设备。
  • 汽车电子: 由于其高可靠性和耐用性,MMBT8550D 也可以应用于汽车电子系统,如传感器、控制单元等。

优势

  • 高频性能: 100 MHz 的特征频率使其适合高频信号处理。
  • 低噪声: 低饱和电压和低漏电流确保了低噪声操作。
  • 高可靠性: 由先科生产,保证了高质量和可靠性。
  • 小型化封装: TO-236-3 封装适合现代电子产品中的空间有限场景。

使用注意事项

  • 过热保护: 确保在使用过程中不超过最大功率(350 mW)以避免过热。
  • 电压限制: 不要超过集射极击穿电压(25 V)以防止损坏。
  • 静态防护: 在处理时应注意静态电荷防护,以避免静电损伤。

总之,MMBT8550D 是一种功能强大、性能优异的小信号PNP型三极管,广泛适用于各种需要高频信号放大和开关控制的电子系统。其高频特性、低噪声性能和小型化封装使其成为许多工程师和设计师的首选元件。

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
