2N4403 产品概述

一、主要参数

  • 晶体管类型:PNP
  • 集电极电流 Ic:600 mA(最大)
  • 集–射极击穿电压 Vceo:40 V
  • 功耗 Pd:625 mW(封装限制,环境温度相关)
  • 直流电流增益 hFE:约100(测试条件:Ic=150 mA,VCE=2 V)
  • 特征频率 fT:200 MHz(小信号放大带宽参考)
  • 集电极截止电流 Icbo:约50 nA(室温)
  • 集电极饱和电压 VCE(sat):约750 mV(条件示例:Ic=500 mA,IB=50 mA)
  • 射基极击穿电压 Vebo:5 V
  • 品牌:BLUE ROCKET,封装:TO-92-3,数量:1 件

二、产品特点

2N4403 为小信号 PNP 三极管,具备较高的极限集电极电流能力与较宽的高频响应(fT≈200 MHz),在中等电流范围内仍保持较好的直流增益(hFE≈100)。低的漏电流(Icbo≈50 nA)有利于高阻态下的静态性能。TO-92 通孔封装适合手工焊接与快速原型开发。

三、典型应用

  • 小信号放大器、高频放大电路(受限于功耗和偏置条件)
  • 高侧开关与驱动电路(在 PNP 型高侧配置时优先使用)
  • 推挽输出级或互补放大器的 PNP 对管
  • 通用开关与驱动负载(注意饱和压降与功耗限制)

四、使用建议与设计注意事项

  • 功耗控制:TO-92 封装的 Pd 限制较低(625 mW),实际使用时应确保 VCE×Ic 不超过安全范围,必要时采用散热或降低工作电流。
  • 饱和与开关:在开关应用中应保证足够的基极驱动电流(IB≈Ic/(实际hFE在饱和时显著下降)),以减小 VCE(sat)。规格中给出的 750 mV(Ic=500 mA)为参考,设计时应预留裕量。
  • 基极–射极反向:Vebo=5 V,切勿使基极对射极承受超过该值的反向电压,以免损坏结结构。
  • 高频性能:fT≈200 MHz 表明在小信号高频放大有良好潜力,但在高频应用中需注意寄生电容与布局,避免失真或自激振荡。
  • 偏置与温漂:hFE 随温度和电流变化明显,精密放大器需考虑温度补偿与负反馈稳定增益。
  • 引脚与封装:TO-92-3 适合通孔安装,具体引脚排列请参考厂商封装图纸并在电路板布局时考虑焊接和散热。

五、封装与机械信息

BLUE ROCKET 提供的 2N4403 为 TO-92-3 通孔塑封,体积小、便于手工焊接与点样测试。该封装适合低至中等功率应用的快速验证与小批量生产。批量装配时可考虑 SOT-23 等表贴替代型号以优化空间与散热。

六、采购与存储

本条目数量为 1 个 PNP 三极管,品牌 BLUE ROCKET。存储建议干燥、防潮、防静电并避免高温(通常应遵循厂商提供的储存条件),长期库存应注意防止引脚氧化。购买时请核对批号与封装图纸,以确保引脚排列和参数满足设计要求。

总结:2N4403(BLUE ROCKET,TO-92)是一款适用于中等电流、小信号放大与高侧开关的 PNP 三极管,具有良好的增益和高频特性,但在功耗和基极反向耐压方面需要在设计中予以留意。

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
