MMBT4403 产品概述

概要

MMBT4403 是由台湾迪嘉(TWGMC)制造的一款高性能三极管(BJT),属于PNP类型。该器件以其优秀的电气特性和广泛的应用场景而受到广泛关注,特别是在需要高频率和高电流驱动的电子系统中。

基础参数

  • 功率(Pd): 300 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放大器和开关元件,三极管广泛应用于各种电子设备。
  • 工作温度: -55℃ ~ +150℃
    • 这个宽泛的工作温度范围使得MMBT4403适用于多种环境下的应用,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信号放大、开关控制等场景。

电气特性

  • 特征频率(fT): 200 MHz
    • 高特征频率表明该三极管能够处理高频信号,这使得它非常适合用于通信设备、射频放大器和其他高频应用。
  • 直流电流增益(hFE@Ic,Vce): 100 @ 150 mA, 2 V
    • 直流电流增益是衡量三极管放大能力的一个重要指标。MMBT4403在150 mA的集电极电流和2 V的集电极-发射极电压下具有100的增益,这意味着它可以有效地放大基极输入信号。
  • 集射极击穿电压(Vceo): 40 V
    • 集射极击穿电压是指在基极开路条件下,集电极与发射极之间允许的最大电压。MMBT4403的40 V击穿电压提供了足够的安全余量,防止因过压而导致损坏。
  • 集电极-发射极饱和电压(VCE(sat)@Ic,Ib): 400 mV @ 150 mA, 15 mA
    • 在饱和状态下,MMBT4403的集电极-发射极电压仅为400 mV,这意味着在开关应用中能耗较低,效率较高。
  • 集电极截止电流(Icbo): 100 nA
    • 当基极开路时,集电极截止电流非常小(100 nA),这表明在静态状态下能耗非常低。
  • 集电极电流(Ic): 600 mA
    • 最大允许的集电极电流为600 mA,这使得MMBT4403能够驱动较大的负载或提供较高的输出电流。

封装

  • 封装类型: SOT-23
    • SOT-23封装是一种小型化封装,适合于空间有限但需要高性能的应用场景。这种封装方式不仅节省空间,还能提高散热效率。

应用场景

信号放大

由于其高特征频率和良好的直流电流增益,MMBT4403非常适合用于音频和视频信号放大器、通信设备中的前端放大阶段,以及其他需要高频信号处理的场景。

开关应用

在开关应用中,MMBT4403的低饱和电压和高集电极电流能力使其成为理想选择。它可以用于驱动继电器、LED灯、电机等负载,并且能提供快速的开关速度和低能耗。

传感器和检测器

MMBT4403也可以用于传感器和检测器的前端放大阶段,因为其高增益和低噪声特性能够有效地放大微弱信号。

总结

MMBT4403是一款功能强大、性能优异的PNP三极管,适用于各种需要高频率、高电流驱动和低能耗的电子系统。其宽泛的工作温度范围、低饱和电压以及高特征频率,使其成为多种应用场景中的首选器件。无论是在信号放大、开关控制还是传感器检测等领域,MMBT4403都能提供出色的性能和可靠性。因此,如果您正在寻找一款高性能、三极管来满足您的设计需求,MMBT4403绝对值得考虑。

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
