2N3904 三极管产品概述

概要

2N3904 是一种广泛使用的NPN双极结晶体管(BJT),由多家制造商生产,包括杰盛微(JSMSEMI)等。它属于TO-92-3封装类型,适用于各种电子设备中的低至中功率应用。

基础参数

以下是2N3904三极管的一些关键参数:

  • 功率(Pd): 625 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。
  • 商品分类: 三极管(BJT)

    • 双极结晶体管是一种基本的电子开关和放大器元件。
  • 工作温度: -55℃ ~ +150℃

    • 这个温度范围表明了该三极管在极端环境下的可靠性和耐用性。
  • 晶体管类型: NPN

    • NPN型三极管在基极上施加正电压时会打开,允许集电极和发射极之间流动电流。
  • 直流电流增益(hFE@Ic,Vce): 10 @ 10 mA, 1 V

    • 这个参数表示基极输入电流与集电极输出电流之间的倍增关系,在特定条件下(Ic = 10 mA,Vce = 1 V)。
  • 集射极击穿电压(Vceo): 40 V

    • 当没有基极输入时,集电极和发射极之间可以承受的最大电压。
  • 集电极-发射极饱和电压(VCE(sat)@Ic,Ib): 300 mV

    • 在饱和状态下(即三极管完全打开),集电极和发射极之间的电压降。
  • 集电极截止电流(Icbo): 100 nA

    • 当基极和发射极短接时,集电极和发射极之间的漏电流。
  • 集电极电流(Ic): 200 mA

    • 这是该三极管可以承受的最大连续集电极电流。

应用场景

2N3904 三极管由于其良好的性能和经济性,广泛应用于以下几个领域:

  1. 放大器和开关电路

    • 由于其较高的直流电流增益和较低的饱和电压,2N3904 适合用于小信号放大、音频放大以及数字逻辑门电路中的开关应用。
  2. 驱动器和接口电路

    • 可用于驱动小型电机、继电器、LED灯等负载,也可以作为接口电路中的缓冲器或驱动器。
  3. 测量和检测电路

    • 在一些测量和检测应用中,2N3904 可以作为信号放大器或比较器。
  4. 消费电子产品

    • 出现在各种消费电子产品中,如音响设备、电视机、计算机外围设备等。
  5. 工业控制系统

    • 在工业控制系统中,2N3904 可以用于传感器信号处理、控制逻辑门等。

封装和安装

2N3904 采用 TO-92-3 封装,这是一种小型、经济且易于安装的封装形式。这种封装适合于手工焊接或自动化生产线上的安装。

使用注意事项

  • 热管理: 尽管2N3904具有较高的工作温度范围,但在高功率应用中仍需要注意散热问题,以避免过热导致的性能下降或损坏。

  • 电压限制: 确保操作电压不超过指定的集射极击穿电压(Vceo),以防止三极管损坏。

  • 静电保护: 在处理和安装过程中,应采取适当的静电保护措施,以防止静电放电对元件造成损害。

总结

2N3904 是一种功能强大、成本低廉且广泛应用的NPN三极管。其优异的性能参数和广泛的应用场景使其成为电子工程师和设计师的首选元件之一。通过了解其基础参数和使用注意事项,可以更好地利用这一元件来设计和构建高效、可靠的电子系统。

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
